The similarities between the two contests were uncanny at times, but they all were pleasing. We do not like waiting for our contests to start and to see you all in action again. Thankfully, the August Challenge did not keep us waiting for long. Starting on the very first day of August.
We were among the participants and their artistry as soon as the contest started. The problems of Constantin Sokol, Devendra Agarwal, Dmytro Berezin, Lalit Kundu, Pavel Sheftelevich, Praveen Dhinwa, Sergey Nagin, Vinayak Garg, & Vitalij Kozhukhivskij welcomed the participants with a promise of rather pleasing & testing ten days ahead. The problem set was tested for the contest by Hiroto Sekido & Praveen Dhinwa, both of whom made sure that the participants enjoy trying their hands on each of them. That was all that we needed and perhaps you too.
The contest opened to the flurry of submissions, which kept coming in since the first five minutes of the contest, to the very last minute. It took some time for the green ticks to take over the red crosses on the rank table. Thanks to Chef and Gift. While the majority of participants were busy wrapping their gifts from Chef, others were busy playing with The Leaking Robot and it looks like they enjoyed it thoroughly. Once the participants got past these two, awaiting them were the problems on the slightly harder side of balance scale.
As we moved into the contest the flow of submissions on the medium and harder level problems increased. And the number of accepted submissions this time around surpassed the numbers we were seeing in the initial days. While, problems like Cleaning Tables & Chef and Reversing remained the favorites, there were some others who moved on to even harder problems by trying their hands on Sereja and Shuffling, Team Sigma and Fibonacci, and Push the Flow!. By now, the rank list had started giving the glimpses of, who probably could be the final winners in the rank table. But there still was a long way to go and hence everyone was playing cautiously. We too waited till the end of the contest to draw any conclusions regarding the rank table. And now that it’s over, let us introduce you to the winners who made it into our rank tables.
We start with the non-Indian top ten:
Now, the Indian top 20:
Now, let’s move on to the special achievers category, with participants having highest score for Challenge problem, except our winners:
First the non-Indian top 3:
Now, the Indian top three:
Last, but certainly not least, let’s meet our young champs from schools.
First, the non-Indian top 5:
Now, the Indian top 5:
Let’s give all our winners a big round of applause.
Now, let’s take you to yet another highlight of August Challenge 2014, and that’s the final stats of the contest. They are staggering.
All those numbers puts our August Challenge right among the biggest contests we’ve had on contest, in terms of participation as well as submission. And we have only our wonderful team of problem setters and you genius participants to thank. So, we thank you all for being part of the contest and making it such a huge success.
Before we move away from the rank table and onto the final segment of our blog post, let us tell you that the rank table that you see above actually is a lot more interesting. Just like our July Challenge 2014, this time around too we had perfect scores. However, this time around the umber was double. So, while we had three scores of 10 in July, we had six winners with perfect score of 10 this time around.
That brings us to the final segment of the contest, but before we move ahead, let us take you the delicious editorials of August Challenge 2014, cooked up by our editorialist Lalit Kundu. We hope you already have pleasured your taste buds with them, but if you have not. Here they are for you:
We hope you use them to prepare yourself for the upcoming challenges and to rectify any minor mistake you might have made in the past challenges.
With that, we have reached the end of this post. We hope you have enjoyed it as much as we have writing it. We already are running behind our schedule in putting up the blog posts, so without further adieu. It’s Good Bye from our side.
We have tried to tell our side of story, but we are sure you too must be having your own tales from the contest. So, shoot them all, along with any feedback or suggestion you might have for us at: email@example.com
You can also reach us at: (022) – 30797709
That will be all from our side.
TA-TA, see you all at the contests.
It all began with one casual inquiry of one of user regarding one of his goodies that he won long time back, but did not receive. And then a few more similar emails. And then a discussion on another forum. While looking for the missing ones, we dug into our records and found that several goodies have not reached our winners. Also, there are instances where we have not even shipped the winnings. This was serious, almost a crisis, and needed to be addressed soonest. And, before we do that, let us apologise to everyone who has not received the goodie that he/she has won, even if it is just one in number.
We are sorry. We really are.
We tried to identify various reasons of what has caused this, and broadly arrived at a conclusion that our present process is in some mess and needs cleaning. Some of the reasons that we identified for the non delivery of the goodies are:
Many a times, our emails for verifying address do not reach the inbox of our winners but go to the spam folder. So the winners do not know that we have contacted them for seeking their address details.
Sometimes the addresses that we send emails to, are invalid. We cannot contact our winners.
Sometimes the emails that are sent by the winners confirming their details do not reach us. Either they go to spam or are lost somewhere.
Sometimes, we realise very late that our inventory is exhausted and hence we hold on to sending emails until we procure more goodies. This is a lengthy process and we end up losing track of these “to be” sent winners.
Many a times, even after dispatching the goodies, the recipient does not get the goodies. Either the goody gets stuck at the customs (in case of an international shipment) or simply our courier service is doing a shoddy job. Only, sometimes the goody comes back to us and many a times it is lost midway.
We believe that your missing goodie may be because of one of the these reasons. However, if you think, it is not, please let us know.
Identifying the above, we realised that we were doing some things wrong and some things inefficiently. And so, we are going to bring in some changes, and we believe that should solve most of the current crisis. Please read them carefully.
We have decided that we will ship all the winnings only once every month.
Yes, you read that right. Whether it be the Long Challenge, the Cook-Off or the LunchTime or even the Top Contributors of the month, we will dispatch the goodies all together. This will help us streamline our process. Since we are a small team, dispatching it more frequently puts us through a lot of burden and we end up making more mistakes. This may cause a bit of a delay in you getting your winnings but this will ensure that you get it.
After every contest we will send an email to the winners verifying the address that we have of them.
We will try and remove the words like “won” and “congratulations” from the email so that it does not go into your spam.
You will need to update your email and address in your CodeChef profile with the latest email and address that you want us to contact to and send your goodies to. This will make it easier for us to manage your contact data.
If you have not received an email within 4 days of the end of the contest, you can contact us at firstname.lastname@example.org with your contact details and your username mentioning your winning.
The winners will have to respond to the congratulatory mail within 7 days of receiving the email.
If you fail to confirm your contact details or the emails get lost in between (or if any communication has not happened between us on this, within that time period), we request you to contact us on other communication channels like our phone, Facebook or Twitter account, whichever is convenient to you. It has to be done within a week’s time!
If you fail to do so, or we do not have your contact details by this time for the missed email, your goody will be kept on hold and will be shipped in the next month, provided that we get your shipping details.
We will ship the goodies on the 10th of every month.
We will try changing our Courier service for those countries where the shipments get lost in transit.
The main work starts from here for us and we will need your help. We need to track each and every goodie that we send and we want to help you also track your winning.
Once we ship your goody, we get a tracking id from our courier service. We will send you an acknowledgement email of your winning along with the details having this tracking id.
Once you have received the goodie, we need you to acknowledge the the receipt by replying on the same email. This is an extremely crucial step for us to close each case of shipment. If we do not get a confirmation from you after 10 days of sending the goodie, we will try and contact you on email, phone, Facebook wherever we can. If we are unable to reach you for any reason, we will have to consider that the goody has reached you and close the case.
You can still reach out to us in case you have not received it and we will be happy to send you another one.
The above process will come into effect starting now, that is September. Which means that the next shipment will happen on the 10th of October.
We will fix our inventory management issue as well.
Now, let’s talk about all the winnings that have been received by the winners in the past. It includes everyone who has not received any goodie from CodeChef. So, we want you to pay attention.
For winners outside India, due to certain custom rules your goodie might be hanging with concerned department. So, we want you to take a dive into your inbox/spam to search for our congratulatory mail for which you have not received the goodie. Once you have the details, contact us at: email@example.com and we shall get back to you with the status of your goodie, so that you may collect it from the customs department of your country. If your goodie has not been shipped, we will get it shipped to you, and if it’s stuck somewhere we will figure out the way how you can get it.
For winners from India, if you have not received your winnings, you just need to get in touch with us. If we have your tracking id, we track your goodie.
In both the cases, if your goodies have not been shipped, we will ship them to you in the coming cycle, for sure.
It will take a bit of effort from all of us. So, we request you to extend your cooperation in helping you find your missing goodie, as we want you to have it at the earliest and brag about it. We really do.
It has been over five years since CodeChef’s inception. We have hosted plethora of contests, have seen numerous names appearing on the rank tables from all over the globe. We have cherished every single contest and every participant that came along with the same joy and fervour. We took pride in having their names on our rank tables, and many times bragged about it as well. And we do our little bit to acknowledge and encourage the performance by ensuring that their winnings reach them safely & timely. Knowing that the winners will be as happy to receive them as much as we are when sending them. And we do believe in that.
So, whoever you are, wherever you are, if you have ever won a goodie on CodeChef and not received it, we will get it delivered to you. Pretty soon.

The July LunchTime 2014 was set in the glorious backdrop of International Olympiad of Informatics 2014 world finals, which etched a brand new chapter in the Indian programming scene. We got our very first Gold medalist in the world finals, in Akshat Bubna, and the first Indian girl medlaists in Malvika Raj Joshi. If truth be told, the performance of all the four students representing India at the world finals, including Pushkar Mishra & Nihal Pednekar along with the above mentioned two, will be a motivation for many young programmers in coming years.
The anticipation of yet another enthralling contest, we were a tad more excited than should have been. That also could be because we’ve been seeing our young IOI world finalists, with their other counterparts from all over the globe, create their magic time and again in our LunchTime contests. The July LunchTime was another chance to witness that sheer brilliance. So, we stuffed ourselves with just enough breakfast to leave some room for the butterflies in the stomach that we always get, and were all set for the salutation of our youngest programmer friends.
The problem set for the July LunchTime came from Tuan Anh, who has been around long enough to understand the appetite of the budding programmers and to cook up a problem set to satisfy their taste buds. The testing of the problem set was handled by Tasnim Imran Sunny, who tested the problems thoroughly to ensure they are ready to be devoured as soon as they are served. The desert of editorials came from Lalit Kundu, another bright young talent in our problem setting panel. The varied variants of the problem statement as Mandarin translations came from the ubiquitous Minako Kojima and Gedi Zheng, while the Russian translations were provided by Vitalij Kozhukhivskij. With such a decorated problem setting panel, it was now participants’ turn to show up and create their magic. And they did, exactly that as the contest started.
As soon as the problems were unveiled, the submissions started flowing and in the very first minute of the contest, we got our first AC. “Wow! That was fast.” Those were our exact words at that time. We were treated to more surprise when the following two submissions also got accepted. The best thing was that they all came from three different users. But we were most pleased by the third submission. As it was from neo1tech9_7, hailing from Bharti Public School, New Delhi. To see a school student cracking the problem has a thrill of its own. And with that the contest was on.
The July LunchTime 2014 saw a thumping start, with most of the submissions getting accepted. Still, it was too early to predict the future of the contest, so we kept our cool watched the calm and composed moves of the participants. In the first hour of the contest we saw yutaka1999 scamper atop the rank table, closely followed by kaizero & contesant. The scenes on the rank tables remained pretty much unchanged even in the second half of the contest. The story at the bottom half of the table was not all that different either. The likes of labib666, akat, capawesome, and mbrc where fighting their way up the ladder, making it clear that they are equally big threat to the crown holder.
The Indian rank table was equally packed with participants fighting their way up. Some of the popular names were missing from the rank tables, but that did not have any impinge on the nature of the contest. We had some new names in h9k6, darkcoderrises, svineet, and batcrazt making their mark on the big stage. And we were pleased to have them.
Both the rank tables, as always had a mix of new and familiar names, which brings in just the perfect pinch of spice to the contest that keeps us all excited all through it. Who all featured on the rank tables this time around, let us introduce them to you.
We will start with the non-Indian top 10:
Now, we move to our Indian top 10:
A big round of applause to all our winners!
Now, the final stats of the contest:
To have such staggering numbers in any contest is a real delight and to have them in LunchTime just elevates the joy. It also became apparent with the number of submissions on all the four problems of the contest. And we hope to have the same in many more coming contests.
With that we would like to conclude the post, by thanking all you wonderful people for making it such a huge success. If you have any feedback or suggestion for us regarding the contest or in general, send them through at: email@example.com

Till next time, adios everybody.
See you at the contests.
In a memorable scene in Francis Ford Coppola’s “The Godfather: Part II”, Michael Corleone visits his dad, Vito Corleone’s room and remembers many things his dad had taught him. One of those many teachings was to “keep your friends close, but your enemies closer.” That saying of don Corleone is the motivation behind our “Sets” feature, developed by one of our young interns, Kartik Singal. This will help you keep a hawk’s eye on your friends and foes alike. So, in the name of the Godfather, the son, and the legend, Francis F. Coppola, let us give you a brief run on the feature to have you know how things will run in this neighborhood.
To assemble your first Set, you need to go to your profile page, and click on the small “People” icon alongside the edit profile button. Yes that is a new addition to your profile page.
It will open up a new page, where you need to enter your “Set name” and a small description of the set. Because, you know, it’s cool to have a well described set and it helps you remember, what this set is about, as you may want to have different sets for your foes and friends. Your first set gets created.
Now, you can start populating it by adding members to your set by clicking on the “+” icon.
This is where it gets interesting. There are various filtering criterias that you can apply before adding a user to your set. You can filter the members you want to add to your set on the basis of:
His default Programming Language
His Long Contest Rating
Once you have selected your filter and entered value that you want for that filter, you need to “Apply” it before selecting the username to be added to your set. You may get some assistance in adding the value for any filter.
You can apply multiple filters before moving to the Username field. Try and play around with it to see the power of zeroing on the right list of Usernames.
Most of the filters have an auto suggest, except for the “Long & Short Ratings Filter”, where you need to manually enter the rating ranges separated by “::” e.g 2000::3000, which means users who have rating points between 2000 and 3000.
Once you have applied all the filters, you will get a list of the usernames whom all the selected filters apply in the Username field as you type.
Furthermore, you can do a lot more with your sets, including:
Deleting one or more members from your set
Renaming the set
Delete the entire set
View the ranks of your set members in our monthly contests
View their contribution in our discussion forum.
With this functionality at your disposal, it’s now your time to suit up and watch how your friends, and foes as well, are faring on CodeChef.
In creating his feature, Kartik, in the company with our chefs, has done his part in bringing you closer the people that matter to you the most and now it’s all up to you how you want to play around. The idea behind this feature is to apply these sets on various future features that we are going to build. Possibilities are many.
We hope you will love this and make use of it the most. However, if you have any concerns, or find any bugs write them to us at firstname.lastname@example.org.
You can also find Kartik and if you do, feel free to thank him or thrash him for the bugs that may be there.
Or you can just call us at: (022) – 30707709
Till next meeting, farewell everyone.
It is very important that you learn from the past. The lessons you take from the mistakes you’ve made in the past becomes the building blocks of a brighter future ahead for you. We absolutely believe in that and like to take as much learning as possible from every tumble we take, the most recent being our June Cook-Off 2014. After the chaotic June Cook-off we were all set for what may come in the July Cook-Off 2014. Or at least we thought so. But we really were ready this time, and the smooth start to the contest reinforced our believe.
The July Cook-off 2014 opened to a gala reception belittling any opening we ever had for any of our Cook-Offs. And that just broadened the smiles that we had on our faces. It might sound a tad clichéd, but it was a dream start to the contest. Inside the first half an hour of the contest we had broken all the records in terms of participation and suddenly there were high fives floating all over. Not because we had the highest participation till now, but because there was no glitch this time around. However, it was not a long lived joy for us.
As we moved into the contest (after 45 minutes) the scenes at the contest started changing with the submission queue growing farcically. And sadly for us, it never came down. The party was over for us, and it call came down falling like a pack of cards for us. Questions were raised regarding our capabilities and functionalities, and we took them all sportingly and answered them all with all our honesty. We even put up a blog post elaborating everything right and wrong about the July Cook-Off 2014 for everyone to know what exactly happened during the contest.
Every time something like this happens we feel utterly sorry and get sad. And that cannot be described in words. But we do not give up and after every such chaos we shall rise improved and stronger.
While the increased number of queue had affected the initial elation of the contest, it could not deter the joy of the participants. Despite such a major catastrophe, the July Cook-off brought us the highest participation with around 2430 users making a submission in the contest. Even the number of submissions this time around was 11500 plus. So, we can say that the July Cook-off brought with it, a mixed bag of emotions for us. And we hope you enjoyed the highs more than getting annoyed by the lows.
The onus of setting up the Cook-off was on the young shoulders of Roman Rubanenko, who cooked up some really delicious problems, which were equally well tested by Shiplu Hawlader. They both single handedly took blew everyone with the problems, and we hope you enjoyed them thoroughly. The final icing came as the editorials from Praveen Dhinwa, who has cooked editorials precisely to match the taste of the participants. The additional spices in Mandarin and Russian translation came from Minako Kojima & Gedi Zheng, and Vitalij Kozhukhivskij. The problem setting panel as always was bang on target with their problems, and now it was up to the users to feast on them. And how they feasted, we all know now.
The July Cook-off might have been filled with bumps & glitches, but we did had some wonderful performances from participants from all over the globe. The fight between sourspinach and gennady.korotkevich, which started from the very first moment of the contest, went all the way to the wire, where the mighty Gennady triumphed everyone to take home the July Cook-Off. We had some brilliant performances from Indian participants as well, with anudeep2011 & triveni. And to introduce you to all the winners of the Cook-Off, let us take you through our rank tables.
We start with the non-Indian top ten:
And now our Indian top 5:
A big round of applause for our wonderful winners and their fortitude.
Now, let us present you the final stats of the contest:
After all that happened during the contest, to see such amazing numbers on the stat chart is just heavenly. And we have no one, but all you wonderful people to thank for sticking with us through thick and thin. So, once again a big thanks to you all and high five.
With that we come to the end of the post, and to close the post on a sweet end let us give you the editorials from our August contests. They will help you better prepare for the coming contests, and with September Challenge going on, we’d suggest you go through them well.
So, let the nom begin:
Do share your feedback and queries on the editorials in the comment section.
That brings us to the end of the blog post, and while we cook that up for you, why don’t you guys share your thoughts on the contest, the blog post, or any other topic that you might have in your mind with us at email@example.com
We will come back again with a new blog post and a new story.
Till then adios amigos.
See you at the contests.
We remember that in the year 2009, immediately after the one and only online contest that we hosted onsite the “SnackDown”, we had conducted a survey on the features most needed by the finalists of that contest. And Facebook connect was unanimously lying at the bottom.
However, in a rare “do it against the users’ wish” move, we went ahead and implemented the Facebook login a year later. We were convinced that most of us would be on Facebook sooner rather than later and bragging about our achievements is not such a passé even for the geekiest among us all. And this did help to quite a few of us, specially to reach out to the new programmers.
Since then, the frequent changes by Facebook have left us trailing behind in terms of keeping up with their API. This has resulted in sporadic bugs here and there. Therefore, when our intern Karandeep Bhatia joined the team, our chefs decided to take up all the issues that you faced with Facebook connect and address them all at once. They have been working rigorously on revamping the Facebook login module and have sprinkled a pinch of new publishing events as well. And, starting today, we have sugared the pot for you all.
Let us take you through what has been revamped & what new is waiting for you.
New ways to broadcast your achievements:
If you have connected your Facebook accounts with CodeChef you can now simply go to permissions or straight to “Facebook Settings” in your profile, and can choose the events, you want to share or publish with your family & friends on Facebook.
You can brag about each of the following events:
Well, that is a lot of sharing, so, you better get on it. Go ahead connect your Facebook account and let your friends & family know you’re awesome.
The feature is still in its infancy days, so if you come across any fumble here & there kindly do report them to us. As you, have done in the past. However, before you contact us, if you face any issues with login, please remove CodeChef app from your Facebook Apps list and try re-connecting again. It is your profile, it is your community, help us optimize it. All we can do is give a gentle “Poke” with the little things we do, and hope that you “Like” it.
So, do let us know what you think of the recent developments. You can write to us at firstname.lastname@example.org or can give us a call at the following number:
Office: (022) – 30797709 (Mon – Fri 11am to 8pm)
Till next time.
Our July was happy and busy. Of course, there were times when we found ourselves wishing for it to get over, but we are not going to talk about them. It is a fresh blog post (a tad delayed as well), so let us get on with it. The July Long Challenge 2014 concealed too much action in its confines for us all and we hope you enjoyed it thoroughly. It has been five years now, but still the fear of goofing up a contest is always there in our subliminal minds whenever we are nearing one. The arrival of July Challenge was not different. However, contrary to some of our infamous goof ups, it was a walk down the park. Yes, it did start with six problems, but their mesmerizing flavors kept everyone far from missing the remaining four. Moreover, taking advantage of that, we served the remaining four problems, two on the same day, & two on the second day of the contest, with lots of love poured on them.
The problem-setting panel for the July Challenge featured Gerald Agapov, Vitaliy Herasymiv, Lalit Kundu, Vivek Hamirwasia, Vitalij Kozhukhivskij, Sergey Nagin, and Dmytro Berezin, all of whom have so many great contests against their names, and it was utmost pleasing to have them. We hope you enjoyed cracking the problems, and perhaps would have taken a lesson or two from all of them. Shang Jingbo and Gerald Agapov, both of them who have immaculate taste as a problem setter, did the testing of the problems to be contest ready. The cherry on top as the editorials came from our young editorialist Devendra Agarwal. The extra flavors in Mandarin and Russian translations came from Minako Kojima & Gedi Zheng and Sergey Kulik respectively. It is always nice to have different flavors for the problems and we are sure you enjoyed them meticulously. With that, let us move away from the pleasantries and relive the wonderful moments from the contest.
The eyes of the participants lit up as soon as the problems were unveiled. And suddenly everyone forgot that four of the problems were missing. Without disturbing them, we started working towards the remaining problems, of which two were added on the very same day, while the other two were served during the first weekend. The contest opened with a accepted submission on Count Substrings, which turned out to be the easiest problem of the contest and fetched maximum submissions. And we are sure a majority of them were accepted. With a over 1K submissions less than Count Substrings, Reach The Point was the second most popular problem of the contest. They both saw plethora of accepted submissions and became the reason of smile to many.
As the contest progressed, the participants started enjoying the Garden Game, and Chef and Frogs almost equally. By this time, the remaining two problems were added to the contest, and now we were sailing towards the half way mark of the contest. The period of fun & games was approaching its closure and the race to the top was on. But that doesn’t mean that the fun has to stop, and it did not. Plenty of new users joined the contest in the second half, and the party kept going on.
As we inched towards the final weekend of the July Challenge 2014,we expected the rank tables to be pretty much like what we have had in the past. However, it was nowhere near that. The names topping the charts were not that we had known for long, and the numbers were touching new heights. In the final weekend, we had emkjp sitting atop the rank list with a score of perfect 10 and accompanying were demidenko & stolis. And we were pleased to see new names topping the chart. However, in the back of our mind we were expecting a strike down from the pros in ACRush & mugurelionut, who also were seen on the tables. The Indian rank table was led by djdolls, who this time around had win_ay & praneethiitr accompanying him on the charts. As we approached the final moments of the contest, the big guns snatched the top spots painting the July Challenge 2014 in their own color. However, it was a close finish with ACRush, mugurelionut, and rns4 all getting a perfect score of 10. It seemed an apt ending to a contest, which had almost every aspect of a fun filled competitive programming contest. And, we congratulate all the participants for making it so.
Now, let us meet our winners.
We start with the non-Indian top 10:
The Indian top twenty:
Now, let us move towards the special achievers category.
We start with the the little wizards from schools outside India:
Now, from schools in India:
Finally, the special achievers with highest score for the challenge problem GERALD09, apart from the winners:
First, the non-Indian top three:
Now, the Indian top three:
Congratulations to all the winners for their brilliant performance and all the best for the coming one.
Now, let us give you a tad devilish stats for the July Challenge 2014. Why do we call it devilish? You check yourself.
That is all that we have for you from our July Challenge 2014. We are sure you all must be having your own interesting set of stories about the contest and we want to hear them all. So, shoot them to us at email@example.com
With that we bring down curtains to the tale of July Challenge 2014 and move towards cooking up another tale for the July Cook-off 2014. We will be serving it soon. So keep watching this space.
Till then, it’s bye-bye from CodeChef.
See you all at the contests.
