When we sat for June Challenge 2014, we had no idea what is waiting for us at the other end. We were optimistic, like always, and were hoping for a good contest, with some smiling faces in the end. However, as soon as we learnt that the contest is starting with eight problems, the number of smiling faces that we were expecting reduced. Now, all we wanted was a good, fun filled ten days of healthy competitive programming. And thankfully, we got that, actually we got more than we wanted.
The June Challenge 2014 was set by the experienced problem setting panel comprising Dmytro Berezin, Gedi Zheng, Istvan Nagy, Lalit Kundu, Sergey Kulik, Sergey Nagin, Vitaliy Herasymiv, and Vivek Hamirwasia. The problems were tested contest-ready by Shiplu Hawlader, who ensured that the problem set is well balanced to everybody’s skill level. The explanatory editorials for the problems came from Praveen Dhinwa, and we are sure by now you would have tasted them all. The spices in the form of Mandarin & Russian translations came from Minako Kojima & Gedi Zheng, and Sergey Kulik respectively. When you have such decorated problem-setting panel, a dazzling contest becomes obvious. And we were expectant of that too.
The June challenge might have started with eight problems in the offering, and they all were greeted graciously. The initial bombardment of submission was on CHEFZOT, which became the first problem to have an AC by dream_71 in the sixth minute of the contest. And after that, the submissions just kept on coming. Everyone wanted a piece of Chef and Subarray, and almost everybody got that. While the participants were having fun with Guessing Game, Forgot Password, Chef and Digit Jumps, and Maxim and Progressions our problem setters were busy garnishing the ninth & tenth problems. And soon the Little Elephant and Blocks and DARTS501 were on the table, ready to be munched on.
With all the ten problems in the offering, the game was full on, with everybody firing all their cylinders to top the tables. While the major fight in the Indian table was between triveni, akash4983, and anudeep2011, the international table was all about the triangular battle between mugurelionut, sokian, & kevinsogo. The view at the top of the table in the final days of the contest was rather usual, with not many unexpected names. However, triveni was one surprise package in the contest, and certainly someone to look forward to in the near future. To know who stood where when the contest ended on 16th June 2014, let us take you through the rank tables.
We start with the non-Indian top 10:
The Indian top 20:
We now move on to our special achievers category, and we start with the users who had highest scores for challenge problem DARTS501:

That will be all folks.
See you at the contests.
With every LunchTime contest, we are seeing new names announcing their arrival at the big stage. Some of them have established themselves as a force to be reckoned with in the world-programming circle, while some others are in the process of paving their way to glory. Moreover, it gives us immense pleasure to have been a part of this wonderful journey that we all have embarked upon. There is still a long way to go, and we will come across many new names, many new champions along the way. And we will celebrate them all with the same joy & fervor. For now, it is time to relive the course of May LunchTime 2014.
The May LunchTime 2014 like all other LunchTime contests we have had started on a pleasing note, with not much rush. However, the urgency was there among the participants to emerge atop the rank list. And the fight was on right from the beginning. The first one to get the green tick of happiness was yutaka1999, Kaisei Junior High School and Senior High School, Japan who cracked the APPROX2 problem with his first submission in the seventh minute of the contest. However, after the initial bang, he had to wait for a good half an hour to see another of those green ticks.
Unlike yutaka1999, kaizero of Seoul Science High School, South Korea was not so lucky with his first submission and got his first accepted submission in the fifteenth minute on DIVSUBS. Now, he might have been a late bloomer in the contest, but after solving the first problem, kaizero never looked back and in next 30 minutes, he cracked the APPROX2 & BNGAME as well. With three problems in his kitty in the first hour of the contest, there were not many doubting kaizero as the winner for the May LunchTime. However, those on the rank tables had different thoughts.
Inside the first hour of the contest, we saw nihalpi1 of Late P.B. Jog Junior College, Pune closing up on kaizero and we got right behind him. Like we do for all our participants. Soon, yutaka1999 & zeulb overtook nihalpi1. Moreover, after the first hour of the contest it seemed as the final race to the top. However, kaizero did not made life easy for them in the fast lane and firmly held on to his position atop the rank table. Thus claimed his first ever LunchTime. Congratulations to him on his blistering performance. And to see where his counterparts stood on the rank tables, let us have a tour of the final rank list of our May LunchTime 2014.
We will start with the non-Indian top 10:
Now the Indian top 10:
Congratulations to all the winners.
Here are the final stats of the contest:
Both the rank tables, while had some familiar names, it was the new names that brought the real joy for us. kaizero, our winner was taking part only in his second LunchTime contest, and to have him sitting on top of the rank table will be an encouragement to many new comers. We are sure that the coming LunchTime contests will see many new names and many new winners.
With that, we put an end to the May LunchTime 2014 tale. We hope you all loved it, as much you loved and enjoyed the contest. However, if you still have any tales to tell or quarrels to quarrel, we would love to hear them all. So shoot them all at: email@example.com.
That will be all folks.
See you at the contests.
Bad days indeed! One more CookOff and one more letting you all down. This time we were prepared. We had learnt from our mistakes from the last CookOff and we knew what had to be done (or not done).
The contest started well. It was the contest, which bypassed all our expectations in terms of participation. Moreover, not only was the number of participants huge, it also brought in all the big names into it. And boy, it was a smooth start. In the first half an hour (which is our most testing time) into the contest we had equalled the previous best participation and without any glitch. We were living a dream.
Not for long! Suddenly the submission queue started going up after almost 45 minutes into the contest. And it never quite came down. We had to stop the contest and let the judge work in isolation. The ever robust and dependable SPOJ judge today gave in. We tried all that we could. Also added more servers, but the queue that had accumulated to 1300 pending submissions took close to 15 minutes to reduce.
It happened due to a couple of reasons.
1. The number of submissions were very very high.
2. More importantly, the number of test files for two problems were very high in number (close to 20). These problems had one test case per test file and that is a non optimal configuration for the SPOJ judge. Each test file spawns a new process for the judge and close to 20 test files for each submission in a short contest turned out to be a disaster.
There is also some unseen benefit at the end of the dark day. We have seen by far the highest participation (close to 2430 users making a submission versus 1774 being the previous highest in any contest). And the number of submissions being 11500 plus.
The final stats of the contest are here:
Total Users: 2437
Total Submissions: 11635
Number of distinct users with correct submissions: 2022
Total users from India: 2113
Total users not from India: 324
We are sad and we are sorry. How much cannot be expressed. But we are not giving up. We promise that the next CookOff will be without any glitch and will be a good one.
Cook-Offs are the real test of fortitude, of a programmer. This, because it does not give you long time to plan your move, and by the time you plan your move, your counterparts would have gone far beyond your reach. You need to be quick, and you need to be precise. This miraculous display of speed and accuracy is what makes them such a special occasion for the participants & for us. We have seen some thrilling Cook-Offs in the past, and the May Cook-Off 2014 certainly can be placed among them.
Before we proceed with the blog post & tell you how the contest was, let us thank the individuals responsible for it. The celebrated problem setting panel for the May Cook-Off 2014 featured names, which when you see them, you know an excellent contest is cooking up. The problem set came from the 2014 ACM ICPC world finalist Anudeep Nekkanti, which on its own was a highlight of the contest. Add to that, tester & Russian translator Gerald Agapov, in company with editorialist Praveen Dhinwa and you have the recipe of a contest of highest order. The Mandarin flavor of the problem set came from the pervasive Minako Kojima and Gedi Zheng. Thank you guys, for always being there for us all and delivering such splendid contests, one after another.
The May Cook-Off showed sparks of a great contest right from the first minute, as Gennady Korotkevich cracked ANUUND in his first attempt, in the first minute of the contest. This exemplary display of speed and accuracy, made it clear to all the participants that they have to be on their toes if they have to be any competition to him. This was a true test of talent and pedigree for many claimants of the throne. With the likes of Myongsu Cha, Andy Y.F. Huang, & Kazuhiro Hosaka on the rank tables, it certainly was never going to be a cakewalk for the Cook-Off-pro Gennady as well. Or so we thought. As it turns out, it actually was a cakewalk for Gennady, as it took him only six submissions to crack the five problems and seal the victory. Remember we talked about pace & precision, this exactly is what we were talking about.
While the other participants were busy piling up submissions on Ups and Downs, or trying hard to crack Build the Tree. Gennady was comfortably sitting atop the rank table, may be with a grin. Even the juggernauts like uwi, mugurelionut, ballon_ziq, Fdg, & many others had a tough time cracking all the problems. So, we were not surprised to see the low submission count and were pleased with the outcome on the rank tables.
While the non-Indian rank table had some familiar names going at each other, the Indian rank table was no different either. We had balajiganapath, the popular djdolls, smithinsu, xorfire & many others fighting it out for the top spot in the Indian table.
Let us take tour-de-rank-tables, to meet our winners and know who stood where when the clock struck 12.
We start with the non-Indian rank table:
Now the Indian rank table:
Congratulations to all the winners.
Now, here are the final stats of the contest:
That sums up the May Cook-Off 2014. The contest was a display of some fine artisanship from both, problem setting panel and participants. We hope you enjoyed every bit of it, as we did. To understand the best approach towards cracking those problems & many more to come, we suggest, you go through the editorials of the contest and try them once again in practice section.
With that we draw curtains on the May Cook-off 2014 and move towards yet another delayed blog post for May LunchTime 2014. It was our anniversary LunchTime, so we try and not to delay it any further and will come back soon with all the celebratory details.
Till next time, enjoy the beautiful monsoon around, and send us all your love, feedback, or your any monsoon trip you are planning at firstname.lastname@example.org. We would love to join you. You can also ring us at (022) – 30797709 (On weekdays from 11:00 am to 8:00 pm)
Long Challenges are special. They have always been like that. To us and we are sure to many of you. And we all have our own sweet reasons for that. If you are a beginner, you will cherish them for all the learning that you get out of them, while if you are a pro, it gives you enough time to polish, plan, and present your best move. Whichever side of spectrum you are in, we love seeing you all fight it out during the ten days of our Long Challenges.
With all that, our May Challenge 2014 was a special one for one more reason. It was the first instance when a premier institute in Indian had introduced CodeChef in their admission curriculum. Indraprastha Institute of Information Technology (IIIT-Delhi) in one of its kind move required the M. Tech applicants to take part in our May Challenge 2014. The entire details of the program can be read here. We thank the management of IIITD and hope the applicants had a great time participating in the contest.
Now, let us have a tour-de-May Challenge 2014. The post has already been delayed for quite a long time, so, without further adieu we will try to cover as many highlights of those ten days in as few words as possible.
The May Challenge started on a pleasing note with two accepted submissions inside the first five minutes of the contest. Both were on OJUMPS, which turned out to be the easiest problem and received around 4.5k submissions during the course of the competition. Newbies making their first submission in the contest enjoyed the easier problems in the first half of the contest, which is always a great sign. Problems that saw maximum submissions during the contest were Stone, Compilers and parsers, and Chef and Strange Matrix. We hope you enjoyed them too.
After the easy first half, the race to the top of the rank table got serious with avolchek and djdolls making it tough for their rivals to dethrone them. And after ruling the rank tables in the first half of the contest, this was expected of them. However, it was not a smooth sail even for them. They too had a tough time solving the mystery of Sereja and Subsegment Increasings. And to add to their woes there was The Malaysian Flight Search. And while djdolls successfully defended his rein atop the rank tables, avolchek fell over the precipice of aawisong & mugurelionut ending up at third place in the contest. However, in the end, it was beautiful last leg of the contest to watch. And to know who stood were in the rank tables. Let us take you through them.
We will start with the non-Indian top ten:
Now, the Indian top twenty:
We now move on to our special achievers category.
And we start with the top three Indians with highest scores in challenge problem:
The non-Indian top three:
Now let us meet our little geniuses from schools.
Firstly, the non-Indian top five:
And our Indian top five;
Congratulations to all you brilliant minds. We hope you enjoyed the contest.
All those names in the rank tables made their way through a thick galore of participants from all quarters of the globe. It is worth mentioning that the May Challenge 2014 saw the highest number of participation in any our Long Challenges. And to give you a clear perspective here are the final stats of the contest:
With that whooping figures and plenty of M. Tech aspirants starting their programming journey in the new academic session, the May Challenge 2014 concluded. And left behind so many fond memories to cherish for us all in the coming time. We hope you too have a story or two to share about the May Challenge, and we would love to hear them. So, if you want you can share them with us at email@example.com.
With that, let us bring curtains down on the May Challenge 2014. However, not before we take you to the editorials for the May Challenge 2014. Enjoy the knowledge-filled editorials and sharpen you programming skills for the coming contests.
That is all from CodeChef’s kitchen. Send us your queries & quarrels, while we prepare the next blog post, the May Cook-off 2014.
Till then, adios people.
See you at the contests.
We goofed up. It was avoidable.
This is not the first goof-up that we have faced in a short contest. We have been there and done that. Specially the starting load during a CookOff has been a long standing problem for us. Sometimes the DB was unable to handle our complicated queries while at other times we were syn attacked! The result each time used to be the same. Pissed-off contestants at the start of the contest got soothed by the end by a usually good problem set (which we have no credit to take for but for our awesome problem setters).
We had tried to replicate the load at the start and fix things in our dev environment, but something or the other got left out. There used to be a time, when we would findan issue in a Cook-Off, fix it and then wait for the next CookOff to find the next one. It happened for a while until we took control of things, changed our application architecture, and moved to a new infrastructure!
Just a few days ago a couple of interns had joined the team and I was narrating this whole chain of events to them about how we had to be extremely alert and almost pray to god each time for the first 15 minutes that nothing goes wrong. The ordered food used to get cold in an eternal wait before it could draw our attention on this Sunday night of every month.
And how things have changed since last 6 months where we just think about googling the best restaurants to order the finest food for the 6 of us. And how things have to go wrong this very CookOff!
Among the changes that we had made, now we run our servers on AWS infra. Over the last six months, for our CookOff, we have been running four c3.2xlarge web instances in front of a MySQL RDS instance to handle the ever-growing load.
The load has been keeping well below 1 on these 8 core machines and hence we thought why not test with reducing a couple of servers this time. This was out of sheer curiosity as we have mostly been unable to accurately replicate the load and the behaviour of what happens in the first 5 minutes of our CookOff. Things boomeranged and we all know what ensued. The load shot up to unmanageable proportions and balancing it on the two additional servers took a lot of time.
No, we do not take our production setup very casually as it may sound. And not that we are considering this very lightly. The contest has been extended and things are back on track. And we are left embarrassed. This foolhardy of ours have not only wasted the entire contestant’s time, it also undid the huge effort of our problem setters. We apologise. It was certainly an avoidable situation.
Welcome to yet another delayed blog post from chefs’ kitchen. We have tried earlier, and we have been trying consistently towards it, but somehow we have not been able to deliver our blog posts on time. Nevertheless, we will keep trying. Now that we are here let us have a look back at the April Lunchtime 2014 and all that happened around it. If you have been a constant visitor to our Lunchtime contests, you would have noticed that the competition for a place atop is getting fierce. We have seen several new names from across the globe bringing glory to their schools, and many others are trying hard.
The April Lunchtime is yet another beautiful tale of the fierce competition among the younger breed of programmers across the world. Our problem setter Piyush Kumar, who was making his debut as a CodeChef programmer drafted the battlefield. Welcome aboard Piyush. The problems were aptly tested by our young and vibrant tester Balajiganapathi(apologies for missing his name initially). The Lunchtime-veteran Sergey Kulik wrote editorials and Russian translations for them. With all his experience, he churned out some luscious editorials, and we are sure you enjoyed them thoroughly. Among the others who decked the problem-setting panel, there were Minako Kojima and Gedi Zheng who contributed the Mandarin translations of the problem. All the delicacies from our problem-setting panel kept the participants engrossed for the entire three-hour duration of the contest. Moreover, while some were going on with the contest with absolute ease, there were some perplexed faces as well. Amid those faces there were our winners somewhere working their way up the ladder.
The April Lunchtime 2014 was a bit on the slower side, as far as the correct submissions are concerned. And although we did received significant amount of submissions by the end of the contest, the number of correct submissions was a tad on the lower side when compared to some of the recent Lunchtimes we have had. However, that did not hamper the quality of contest and we saw some brilliant performances. Moreover, few stood above the others.
The performances that caught us and everybody else by surprise came from maicaifou, dzy493941464, shizhouxing, fancycoder, and zcc598066456. Hailing from China, these fabulous five were taking part in their first Lunchtime contest ever. Finishing the competition among the top five, dzy493941464, shizhouxing, zcc598066456, and fancycoder have been around on CodeChef and have participated in our monthly contests earlier. However, it was the debut for maicaifou. And a gleaming one, we must say. What made the competition among these five even more exciting was the fact that zcc598066456, maicaifou, and shizhouxing were from the same school – Zhenhai High School, China. Now, we do not know for sure, but it certainly would have sparked a slight inter-school rivalry. That is a good one to have.
We think you all must have such competitive rivalries going on in your schools; some might have it in sports, some in academics, and some in competitive programming. And, we would love to listen about all of them. Also, if you have toppled any of your schoolmates in this or any previous lunchtime, do share it with us. You can even share with us, the results of all the Lunchtime participants from your school. It is always good to be competitive in life, so, play hard, play fair. Now, let us have a look at the victors of our April Lunchtime 2014.
Firstly, the non-Indian top 10:
Now, our Indian Top 10:
Heartiest congratulations to all the stars of our rank tables.
Now, we look at the final stats for the contest:
The non-Indian rank table, while was dominated by students from China (7 out of 10), our Indian rank table had some popular names in meteora, akshatb42, nihalpi1, and many more. These names and many of their companions will be shining big around the Indian programming circle in coming days. So, keep a watch on them. You too can carve your name among the finest programmers around the world; all you need to do is take a start. And we believe our Lunchtime programming series can give you that.
We hope to see many of you taking part in our Lunchtime contests in coming days. And with that we will wind up this post of April Lunchtime, and move towards the May Lunchtime 2014.
For any feedback, queries, or suggestion you can always reach us at firstname.lastname@example.org
That is all from us, for now.
Set on the Easter Sunday, our April Cook-Off 2014 already had a festive tone set for it. With all the colorful Easter parties happening all around, we were delirious about our Cook-Off. By no means, it was less than a fun Easter party. There were loads of people working hard to come up with the best solution to the five problems in the two and half hour extent of the contest. The best thing about this revelry of ours was that we had guests from all over the globe. Therefore, putting our party hats on, we delved into the proceedings of the April Cook-Off 2014. And, with this post, we will relive all those fantastic moments once again.
After the big fat April Challenge 2014, we were high in spirits for our April Cook-Off as well. The Cook-Off was again received with great enthuse by the partakers, and as always it was a sheer treat for us here in the office. As the clock struck 9:30 IST on the hot Sunday night of the Cook-Off, the participants ushered in the contest with their submissions. Unperturbed by its name, most of the submissions in the wee moments of the contest came on SNAPE. With this, the problem setter Vinayak Garg had given most of the participants a reason to smile. While the flurry of submissions continued on SNAPE, there were some trying their hands on other problems also. Although it took some time for them to get hold of the other problems, we started seeing submissions on the other problems as well.
The first half of April Cook-Off 2014 perhaps was the most exciting first half of any Cook-Offs in recent times. We saw plethora of submissions flowing in right from the start, but most of them were on a single problem. Therefore, while SNAPE got a lot of love in the start (that is a strange sounding sentence), the remaining four BICO, TCP, DIREL, and LOGO were not very easy to crack. And, even the total number of submissions combined on all these problems was not even close to that of the SNAPE. This made the second half of the contest a tad dull. Seeing all this, it is only fair to say that the problem set this time around was a tad on the difficult side. However, it was tough to tell so, at the beginning of the contest.
Now, while the falling numbers were marring our initial thrill, the return of gennady.korotkevich gave us some joy. Gennady was making a comeback to the Cook-Offs after 14 months, so it was thrilling as well as gratifying. You can put it on the hard problem set, but his return was in no way the ideal comeback that you dream of. Despite securing the top spot in the rank tables inside the first hour of the contest and holding on to it until the last minute, even he was not able to crack all the five problems and thus the McHefs 3D Logo remained devoid of any submissions. He did give it a shot in the final minutes of the contest, but got no success. However, that had no affect in the outcome of the contest and as expected, he topped the rank table when the clock struck 12:00 pm, the scheduled end time of the contest.
Now, let us meet our winners featuring in the rank tables:
We will start with the non-India top ten:
Now, the Indian top five:
Congratulations to all the participants for their amazing performance.
The final stats for the contest were as follows:
The contest indeed was an exciting one, with some testing problems for the participants. So, let us meet and thank the problem-setting panel for all their efforts. We start with our problem setter Vinayak Garg for the fiery problem set. The tester & Russian translator Gerald Agapov and Mandarin translator Minako Kojima for spicing them up with their translations. Finally, the editorialist Constantine Sokol for providing probably, the most vital dish for this Cook-Off, if you have not tasted them yet, go check them out. They will help you get over the distress of not solving enough problems during the contest.
We hope you will like the editorials and will wield your programming proficiency for many such tests in the future.
We will now be wrapping up this post and move towards the next one in line, the April Lunchtime 2014. However, not before thanking you all for being part of yet another brilliant contest and hope to see you around.
You can always send you love, feedback, and suggestions to us at email@example.com. You can even catch us at (022) – 30797709 (between 11:00 am to 8:00 pm IST during weekdays) for any queries or inquiries you might have.
That will be all from us, for now.
Till next contest, Good-bye everyone.
April, let us just say is the most competitive time of the year. The exam season had just ended, and the race to the admission window is on. Everyone is ready with their preparations for plethora of entrance exams scheduled ahead for them. The rush to the stationary shops is more frequent, than to the playground. In such a competitive time, it is tough to catch someone taking a breather, or asking them about their summer vacation plans. So, we too refrained ourselves from doing that, and instead added more fuel to the burning competition desire with our April Challenge 2014. How did it go? You ask. We will tell you all through this post.
Our long challenges in general have been all about giving the budding programmers an opportunity to learn and compete with the big guns. The first couple of days of the contest see the sea of new comers trying their hands in the problems served. We see many new names featuring in the rank tables in the wee hours of the contest. However, as the contest moves in the nature of the competition changes and that is when the big guns take over. However, the April Challenge 2014 saw a different start with the first submission coming from vineetpaliwal, on POTATOES inside the first five minutes of the contest. It was quite a fascinating start to the contest and set the tone straight for the coming days.
The April Challenge opened up with seven problems, but as the problem setters worked on the remaining three, the participants enjoyed the seven in hands. POTATOES and CNPIIM was the flavor of choice for the newbies, but the presence of vineetpaliwal, fancycoder, dracowane, xorfire_ and some more recognized names, kept everyone on their toes, which ensures a healthy competition during the contest. In the meantime, our problem setters added the remaining three problems in the contest.
With all ten problems on the table, we were all set for the first weekend of the April Challenge 2014, and so were the participants. Moreover, by the end of it, the contest was well on its course to be one of the biggest CodeChef challenges. Leading the Global and Indian ranks by then were Ri Mun-Chol and Gunjan Sharma respectively. To have new names leading the rank tables always adds an exciting punch to the contest. However, their reign atop was not long, and by the mid way into the contest the big guns in vineetpaliwal and mugurelionut took over the rank tables. Thus began the race to the top among the biggies.
The problems created by Shalini Shah, Lalit Kundu, Dmytro Berezin, Bruno Oliveira, Ilya Malinovsky, Sergey Nagin, Anudeep Nekkanti, A Surya Kiran, Gerald Agapov, and Tiancheng Lou put the participants through an enjoyable test to keep up with the competitive environs around. The problems might have been enjoyable, but they certainly were not a walk in the park for many, as even after the first weekend, there were two problems devoid of any submission. Thanks to our testers Shiplu and Md Mahbubul Hasan, who ensured that the problems cater to the wide spectrum of participants rather than being favorites of only the ones on the rank tables. The additional spices in Mandarin and Russian translation came from the ever-present Gerald Agapov, and xiaodao. The immense hardwork put into by our problem-setting panel was nicely rewarded by the participants through the huge number of submissions made during the ten-day course of the contest. However, while POTATOES saw submissions in excess of 5K, the LMATRIX3 only saw four. There was a little something for everyone though, and we hope you had your fare share of fun and competitiveness.
Now let us move towards the rank tables to meet our winners.
First, the Non- Indian Top 10:
Now, the Indian top 20:
Now, let us meet our special achievers.
Firstly, the top five non-Indian school students:

Now, the final figures for the contest:
All those figures put April Challenge 2014 among the biggest long challenges we have had on CodeChef. We hope to have many more of those and to see you all being part of them.
That brings us to the end of this late post for the April Challenge 2014. Nevertheless, before we sign of let us escort you to the desert for the contest in the editorials for the problems of the contest. Therefore, if you had a hard time cracking them up during the contest, these editorials will help you understand the best approach towards solving them and will sharpen your programming skills for the future. So, do go through them thoroughly.
With that, it is time to draw curtains on this April Challenge post and move towards the next posts in line starting from April Cook-Off 2014. We are sorry for putting these posts so late, but trust us we are working on our lethargy and shall be on schedule soon. Until then, kindly be with us.

Till next time, Good-bye everybody.
Our Lunchtime programming series has been a global platform for young programmers to proclaim their advent among the best in the business. Some have already done that in the small span of 10 months of Lunchtimes existence, and many others are in pursuit of it. The likes of acmonster, sy2006, etc. have already become a force to reckon, even in our Long Challenge and Cook-Offs. And while, there is a long way ahead of these young programmers before they establish themselves in the elite club, we think if they carry on in this pace, it should not be long before they reach their destination.
The March Lunchtime 2014 brought to us yet another shinning start, which caught everybody’s attention since the beginning of the series, and perhaps was patiently waiting in the milieu to announce her arrival. Although we knew that eventually it will happen, we just did not knew when. So, there we were waiting for the clock to ring 2:00 PM IST and present to us our first Indian victor in our Lunchtime contests in meteroa. We have done it already, but let us once again join hands to congratulate her on this astonishing feat.
We were, and are still awestruck with the performance of meteroa, and we have all the reasons to be so. Firstly, she is a girl, and although we have had some tremendous girl programmers in our contests, to have one from school is very special. Then, she is home schooled at Chashak Gurukul, which is just mind blowing considering the fact that we get participants from almost all the elite schools around the glove. Finally, the fact that she is there in the IOI Training camp preparing to represent India at the IOI World Finals. It is just too much of excitement to handle. Nevertheless, we like such thrill and would not mind receiving them more often. Therefore, way to go meteora, we are proud of you, and wish you all the best for all the future competitions you will be competing in.
That meteoric performance was not without any competition to slow it down. We saw some nerve wrecking competition in the final hour of the contest. Huzecong, of High School Attached to Hunan Normal University Hunan Province, China and labib666, of BAF Shaheen College Jessore, Bangladesh were trying their best to secure the top spot in the rank table. No one was ready to let go without a solid fight. However, in the end meteora triumphed them all and painted her name all over the rank tables, when the contest ended. And we all had big smile and cheer on our faces.
Despite such a tremendous performance, it is not meteora, who currently tops the March Lunchtime 2014 rank tables. We have tehnar of Saint Petersburg Lyceum 239 Saint Petersburg, Russia with total score of 340 topping meteora’s score of 317. That is because tehnar updated his institution name after the contest. It would have been interesting to see how meteora would have combated had he been there on the rank tables during the contest. However, we are sure that we will get plenty of chances to experience many such contests in coming Lunchtime contest. Moreover, to be sure that you are there on the rank tables, right from the beginning make sure that you have updated your school name in your profile.
Now, let us meet our top performing candidates for March Lunchtime 2014:
Firstly, the non-Indian top 10:

Congratulations to all the winners for their tremendous performance!
Now, let us see the numbers that matters for our March Lunchtime:
With so many students, enjoying the lip-smacking problem set of our lunchtime, let us meet, and thank our amazing problem-setting panel responsible for it. Multi-tasking Sergey Kulik, who once again was the Russian translator for the contest, prepared the problem set and to add more to his duties for the contest, he was the editorialist for the contest. Phew, that is a lot of hats on a single head. Nevertheless, we must say he donned them all to perfection. Roman Rubanenko tested the problem set, while Minako Kojima provided the Mandarin translation for the problem set. It is always gratifying to be in such esteemed company and we hope to remain so in the coming contests as well.
With all that, we conclude this already-delayed March Lunchtime 2014 blog post and move towards the April contests.
The summers are here and we are sure you already have a beautiful summer vacation plan in place. So, enjoy your vacations, but do not miss all the fun here at CodeChef contests.
