It was June of 2013 when we first had our “Lunchtime”, a new addition to our monthly contests. This little contest was aimed at the younger programmers in schools around the world. We have seen it become a regular entry into many school diaries, and some big planners as well. And as with every contest, for every Lunchtime we got feedbacks and suggestions regarding the Lunchtime.
A lot of those talked about the nature of the contest or the problems. And while, we have been constantly working to improve on them, there was one consistent feedback that kept popping up often and it was: “change the time of Lunchtime.” Now, most of these feedbacks were from the school students. So, it was of utmost importance to us that we take them into consideration.
The reasons cited for the time change ranged from it clashing with the timings of institutes for preparation of competitive exams, to it literally clashing with their “Lunchtime” to it falling on odd hours in some countries and few others have schools on Sunday. So, we had to take all of them into consideration and act. And we started thinking about this one.
After putting a lot of thought to it, we decided to shift the contest to a slightly more accessible day, and time. And after a lot of polls, involving all the school students in our database, and some severe mind crunching among the team members, we have finalized on a day and time.
And it is:
Last Saturday of every month from 7:30 pm IST to 10:30 pm IST
It was not only the most voted option in the poll; it was also most viable for everyone. As for the name of the contest, it remains the same and we will continue to call it “Lunchtime.” We like it too much to change. However, if any of you have a name that would suit the timing of the contest and at the same time will have some relevance to the school students, we will happy to hear.
Gentlemen! That will be all from us here at CodeChef. Do let us know your thoughts and opinions on the new timing of the Lunchtime in the comments below. You can also write to us at: firstname.lastname@example.org
Till next time, Sayonara.
Cook-Offs – traditionally have been dominated by the big guns from programming world. The appearance of names like gennady.korotkevich, uwi, ACRush, djdolls, anudeep2011, adurysk atop the rank table has almost become a norm. The programming fraternity knows them pretty well to know their potential and what they are capable of doing when they partake in any contest. That is not to say that they are unbeatable. Like all great champions all those gentlemen and so many others have had off days at work, giving us some crunchy post contest tidbits to munch on. But the January Cook-Off 2016 was not about them. In fact it was not about many of the familiar names you might have seen on the rank tables.
So, who was it about? You ask.
Well, it’s a tale of three young programmers. But, before we move ahead, let us tell you that none of these three programmers have won the contest. And while we have immense respect for everyone claiming the top spots in our contests, we are sure that even the biggies from programming world will admire what these young lads have achieved. So, without further adieu let’s meet the programmers in question here: meteora of Chashak Gurukul (Homeschooling), animesh_f of La Martiniere for Boys, Calcutta, and rajat1603 of Delhi Public School, Dwarka.
In any field you are associated with, the desire to do better than what you did yesterday or the year passed by, is a good indicator of excellence. With just about 10 or 12 Cook-Offs under their belts, these three young programmers have grown in leaps and bounds in the past year or so to emerge as the forces to reckon with. It’s easier to get better when you are starting. However, as you master the craft, the mistakes become fewer, thus making it hard for everyone to focus on those fewer mistakes and improve on them. We’d like to believe that it’s not the case with these three youngsters. As they have a long way to go.
meteora – started the contest by cracking DESTROY inside the first five minutes and then went on to crack FRUITS and CFTREE inside the first 10 minutes. If that’s not impressive, we don’t know what is. animesh_f, started a bit late in the 15th minute of the contest, but he was quick too, to bag those three problems as well. The same was the case with rajat1603. Now, cracking the three problems inside an hour or so after joining the contest is impressive. No questions there. But what impressed us more was the fact that, all of them didn’t gave up on the contest till the very last minute. They tried their hands on the harder problem MXSM as well. And even though they could not get pass it, the sheer attempt was commendable. And we are sure very soon we will see them bagging all five from our Cook-Off.
The perseverance and dedication of these three young programmers placed them among the top 10 Indian participants from our January Cook-Off 2016. On a rank table dominated by students from some of the finest institutions and organizations in and around the world, to have three school kids is absolutely a big feat. It is also sending a good message for anyone getting started on the journey to the programming land. If you are among those getting contented by a problem or two to your name in a contest, it should serve as a fuel for you to try and bag few more. And we would love to see you doing that.
Now, we take a walk through the rank table, featuring some big names and some new names, giving a perspective to, why the performance of these young lads was so praiseworthy.
We start with ROW top 10:
Now, the Indian top 5:
And before we go forward, let us give you the final statistics for the contest.
That will be all from the numbers and statistics part of the contest. Now, if you encountered any problem or doubt during the contest, that still remains unsolved, here are the editorials for the contest to help you out. Go munch on them:
We hope you enjoyed the tale of these three bright lads placing themselves in the top 10 Indian participants of the contest. We are sure that the end of the January Cook-Off 2016, will mark the beginning of greater things for them and it will motivate many new and coming programmers in the future.
That will be all from us here at CodeChef. We will come again with yet another exciting story, from yet another exciting contest.
Till next time, Sayonara.
1st of January, every year, perhaps is the most inspiring day of the year. Everyone is pumped up about the blank slate of 365 days, in front of them. While some want to get in shape “this year”, there are others resolving to read a book every month, start eating healthy, complete their projects, and what not. It’s a strange situation to be in. Simply because, it’s not the first time and it certainly will not be the last time. So, the best way to describe it is “New Year discombobulation”. But it’s long gone now. We are almost 20 days into the New Year and if you still have your resolutions intact “Kudos to you”, if not, “What’s the matter with you?” get your act together.
The good thing is that, you are not alone facing the “New Year discombobulation” we have been there too. This year though we tried to keep our resolutions to ourselves and keep things simple. And with 2016 starting on a Friday, what better way to start the year than the first long challenge of the year, the January Challenge 2016. So, amid the sleepy eyes, and the mildly aching heads we sat down to serve the first course of the year 2016 prepared with lots of love and discipline by Praveen Dhinwa, Dmytro Berezin, Amit Pandey, Vitalii Kozhukhivskyi, Abhra Dasupta, Sergey Nagin, Maksym Bevza, Pavel Sheftelevich, Ke Bi, and Vasya Antoniuk.
It was a little Christmas gift for all you programming enthusiasts from our problem setting panel, who worked all through the holiday season to make the contest happen. Joining these gentlemen on the panel was our testers Misha Chorniy and Vasya Antoniuk, our translators Sergey Kulik (Russian), Team VNOI (Vietnamese) & Hu Zecong (Mandarin), and the language verifier for the contest Rahul Arora. A Very Happy New Year gentlemen and to you all.
Now, let us take you through the events of the first 10 days of the year. It was 1st of January 2016, the spirits were high. Everyone wanted to start the New Year on a happy note, and it came first for sandeep9, who was the first person to crack CHMKTRPS and thus became registered the first AC for the year 2016 in our first challenge of the year. Now, the long challenges traditionally have always been about slow and sure submission flow on all the problems alike. And the fact that it was 1st of January slowed it further down. Inside the first half an hour of the contest we got only 100 submissions. Although what was interesting here was the fact that 7 out of the 10 problems saw at least 1 submission inside the first 30 mins of the contest. And that clearly was a sign of good things to come in the later stages of the contest.
The first weekend of January Challenge 2016 did not bring too much of action. Thanks to the big New Year’s parties, neither rank table, nor the submission flow saw any major spike. However, the picture started changing from Monday. Although, the big popular and familiar names were missing from the rank table, there were quite a few promising ones occupying their slots and holding on to them. And as the cherry on the top, we had Olesya Golub topping the women rank table. We were longing for the Women rank table to feature few names and to get it in the first long challenge of the year was utterly pleasing. We hope that number to go further up in coming long challenges. Now, without further adieu, let us introduce you to the winners of the January Challenge 2016.
As always, we start with ladies.
Top 10 Women Participants (in top 100 participants of the contest):

The floods in Chennai that engulfed the city have passed and the city is coming out from its state of disarray and wreckage. Our empathies are with all those it affected. The spirit of the individuals and organizations that helped out during Chennai’s time of need was truly inspiring.
As everything came to a halt, the ICPC regionals were naturally rescheduled. In the aftermath of the floods, the Chennai ICPC Regionals will now be held on the 23rd of January and undoubtedly, enormous efforts were put in to resurrect this contest. Team CodeChef will visit the regional site to support the teams, help out with registrations, and most importantly see the contest go superbly for everyone.
The CodeChef kitchen is already emptying once again as we leave for the Regionals in anticipation of a great contest and a rejuvenated Chennai.
We hope that with all the combined efforts going into the contest, the teams will have a good environment to code in, and will make this chance to go to the World Finals really count. That being said, our heartiest congratulations to all the teams for making it to the onsite contest. And all the very best for #ICPC2016 regionals.
That’s all from Team CodeChef for now, we will be in with more news from #ICPC2016 soon. Till then, keep coding!
Date: 27th December 2015 Time: 11 AM IST Venue: https://www.codechef.com/LTIME31 Event: December Lunchtime 2015
The challenge began with a flurry of submissions for Distinct Codes that got close to 50% correct submissions ( specifically – 48.66%). Some familiar names kept coming up on the rank tables, case in point kmcode of Omori 7th Junior High School, ptnk131627 of VNU-HCM High School for the Gifted Vietnam and mbrc of South Point High School.
As the young coders raced ahead, they found the Ancient Berland Road to be a tricky terrain. Many slipped, got back up and slipped again as the problem proved a mighty challenger. With 12.99% accuracy on the problem, ABROADS certainly had everyone sweating. Sadly for the coders from Team B it was just a preview of what was to come next.
What’s next you ask? Only the 2nd hardest challenge problem. Computer Network was more like a net of complexity from what our young coders’ submissions told us. Let us throw in some statistics again – what better way is there to show how good a job the problem setters did? 38 submissions with a full score and an accuracy of 5.49% EXNETWRK was the second but last obstacle in the challenge.
Buying Seedlings, is an innocent name for something that has the ferocity of the Terminator. If Jack had bought these instead of the beanstalk beans, he would be in a different kind of hell, even without the giant from his original story. With a total of only 5 full scores, this timid sounding problem painted the submission table red much to the coders’ dismay.
Sitting on the sidelines, watching the challenge go down is interesting to watch, but a huge shout out to our young coders’ enthusiasm that makes us want to host Lunchtime month after month. Another thanks to the following people that make it possible. December Lunchtime: Problem setter & Editorialist: Sergey Kulik Problem Tester: Pavel Sheftelevich Here are some stats to look at: Total users who made a submission: 913 Total Submissions: 4190 Number of distinct users with correct submissions: 856 And now, the winners who braved it all and kept going.
That’s all from December Lunchtime 2015. Watch this space for more contest reports. Until next time then!
The road to December Cook-Off 2015 came through the galore of examinations and preparations. Programmers across the globe were busy honing their skills for the busy ACM ICPC season, while trying to keep up with their exams and trying hard to ensure good pointers. To add more chills to that entire setup, we had the winters in its full glory. All in all, it was a thrilling set up for an exciting two and half hour programming contest and we couldn’t have asked for more. But we got more.
The December Cook-Off 2015 was exactly the night before the ACM ICPC 2015 Amritapuri Regionals. While the teams attending the regionals were trying to stay calm before the big contest, there were participants from all over the globe raring to get their hands on the problems of Misha Chorniy. Amid that mixed batch of participants began our COOK65, the last one for the year 2015.
And what a start it was. Just like a big flashy Sunday party, the December Cook-Off started to 98 ACs out of the first 100 submissions in the contest. All this and we were 10 minutes into the contest. What’s even more exciting was the fact that all of those 100 submissions, and the next 100 to follow came on Chef and Subarrays. Perhaps, every who joined the contest that night made their first submission to Chef and Subarrays. Just to have a nice and smooth start to it. It remained the same way until lebron submitted to Chef and Queries. It was also an AC. So, if we have to sum up the first half an hour of the contest it will be like: 2 problems, lots of ACs, very few WAs, and even fewer TLEs and CEs.
As we moved into the contest, the happy start made way for the fury and rage brought onto the participants by Chef and Vectors, Chef and Tree, and Chef and LCS. If you got your hopes high on your performance into the contest after the green ticks you got on the first and second problem, it must not have felt nice trying your hands on those problems. So, do let us know how it was in the comments section below. The immaculate job by our tester Jingbo Shang ensured the right mix of difficulty levels in the problem set. What did you thought of it?
The flow of the submissions in the second half of the contest did slow down, but the intensity of the competition prevailed till the very last moment. notimesea, who made the first submission into the contest, defended his spot atop the rank tables bravely from the challengers in lebron, alex_2008, Ra16bit, and the mighty ACRush. They all had 4 problems in their account and while ACRush cracked all the problems in the first submission, CHEFVEC took two to crack. And with that, he secured the top slot in the contest. And that was our final Cook-Off for the year 2015. We hope you all enjoyed the contest as much as we did putting it up for you.
Now, let us take you through the rank table to introduce you to the winners of COOK65.
We start with the ROW top 10:
The Indian top 5:
Now, the final stats for the contest:
Congratulations to you all on your performance.
Now, let us serve you the editorials for the December Cook-Off 2015, penned by our young editorialist Pushkar Mishra. We are sure you would have tasted them by now, but if you have not, here they are for you once again.
That will be all from us all here. We hope you had a wonderful 2015 and are ready for an exciting 2016 in front of us.
Till next time, adios.
See you at the contests.
December – whether you like it or not is a time for retrospection. Another year is walking into the sunset, leaving behind loads of memories, some to cheer you up, some to fuel you up for the impending challenges, and hopefully, very few to bring you down. And it’s always good to carry the pleasing ones into your heart, when you are looking at a fresh start. With so many good memories from every contest that we had in the year 2015, we sat down to adorn the final challenge of the year, the December Challenge 2015.
The problems for December Challenge 2015 came from Andrii Omelianenko, Dmytro Berezin, Tapas Jain, Misha Chorniy, Praveen Dhinwa, Maksym Bevza, Sergey Nagin, and Fedor Korobeinikov. The problem setters made sure that we had good ten day party, and to make sure that we do, we had Sergey Kulik testing the problems. With those gentlemen taking care of the platter for December Challenge, there was nothing much we could have asked for.
The flavors for the problems came from Team VNOI (Vietnamese) & Hu Zecong (Mandarin), while Rahul Arora verified the languages for the problems and Praveen Dhinwa took care of the proceedings on the problem setting bench. And finally, the mouthwatering editorials were penned by Kevin Atienza. And that concludes our panel of experts for December Challenge. And when the clock hit 3:00 pm IST on 4th December 2015, the battle to triumph the final long challenge of the year began.
Now, blame it on the winters or the cautious play by the participants, the flow of submissions into the contest wasn’t as fluent as some of its predecessors. And even though the contest started with an AC from jtnydv25 on CHEFST, the road wasn’t smooth for all. Problems CHEFST and PLANEDIV kept the participants busy at the beginning, while there were few others who tried their hand on ORACLCS as well. While those three problems kept the users busy, problems like Trip and Palindromes, Misha and Permutation, Sereja and Dividing, and Tanks, were not easy to pass by. But as you know, a good programmer always finds a way. And find they did. Although not as high in numbers as the earlier problems, but we did get submissions on all the problems.
With every submission on a new problem, the picture of the top end of the rank table was getting clear. And when the December Challenge concluded, it became clearer. Or so we thought. As it turned out, there was some issue with the scores of challenge problem Tanks, due to which a lot of users were getting a score of zero. This brought an interesting twist in the tail of December Challenge, and after a thorough investigation, we figured out the issue and fixed it with the help of our engineering team. The fix in the scores changed the entire picture of rank table in terms of change in positions for many users, while a shift outside the rank table for a few. And to introduce you to all those who made the cut let us take you through the rank tables.
We start with the ladies. Sadly, we do not have any lady coder in the top 100 participants of December Challenge 2015. So, their goodies remain unclaimed. But we are sure very soon we will have them taking up all the key positions on the rank table.
Now let’s meet the men, with the ROW 10:
The Indian top 20:
From colleges to schools, let’s meet our young champions from different schools across India.
Now, it’s time for the ROW top 5:
Finally, it’s time to meet our special achievers in users with highest scores for the challenge problem other than the winners.
We start with the Indian top 3:
Now, the ROW top 3:
Let’s give a big round of applauds to all our winners. We hope you all enjoyed competing with them and that are raring to take their places on the rank tables. And to help you with your preparations, here are the editorials from the contest. We are sure you would enjoy them.
Now, before we pull curtains on this final long challenge blog post of the year 2015, let us give you the stats for the contest.
That will be all from the Chef’s kitchen here at CodeChef for the December Challenge 2015. We will soon return with the tale from the freezing two and half hours of the December Cook-Off 2015.
But till then, keep your fingers warm and keep coding.
See you at the contests.
