March was a busy month for us. After the initial packed schedule with the anniversary contests and the long challenge, soon we found ourselves up close with the March Cook-Off 2014. Now, while some might whine about their packed calendars, we like ours to be that way. After the blistering March Challenge, we were keyed up to see what the Cook-Off has to offer to us. And to give you a hint how it went, let us say we were all on the edge of our seats by the end of it, which pretty much states the nature of the contest. How we reached there? We will tell you all.
Before we jump into the proceedings of the March Cook-Off 2014, let’s first meet the people responsible for it. Konstantin Sokol created the problem set for the contest, which was then tested, and translated in Russian by Gerald Agapov to ensure that they are ready to put the participants through a stirring test. And they indeed were ready. The desert for the contest in the editorials came from Tasnim Imran Sunny, to let the participant put an apt end to their quest for the perfect solution of every problem they tried on. The extra spice in Mandarin translation came from Minako Kojima, who has been taking care of almost all our Mandarin translations. The best compliment to the hardwork that our problem-setting panel pours into all our contests is the huge number of participation from programmers across the globe, and the March Cook-Off too saw that.
In the warm Sunday night, our Cook-Off brought the right mix of action and calmness in its two and half hours for everyone who participated. With the coolers in place, it was only the contest that was heating up with the action between different participants, who barged into the contest right from the start. The first accepted submission came inside the five minutes of the contest on Dividing Stamps. And seldom have we seen that a submission in such quick time came from a new name. This time was no exception. The first one to make his mark on the contest was the mugrelionut. Seeing the start some pundits would have started writing the fate of the contest. And we will not blame them. Most of the times the big guns sweep away the contest even before the other participants get hold of the problem set. However, this was one of those rare occasions, when the fate of the contest is not sealed until it is over.
We moved into the contest, with submissions coming in from all directions. While the submissions from newbies were seeing all sorts of result, it was green tick for most of the submissions from the pros. The ciphered moves of the pros were rarely stalled all through the contest, and with one hour left into the contest, we had uwi comfortably sitting atop the rank tables, followed by mugurelionut. It was not a surprise but what followed it certainly was a surprise, and a rather pleasing one at that.
The final hour of the contest saw most of the action, as the fight to the top started heating. The steady cruise of seasoned campaigners to the top was disturbed by the arrival of the new comers like dreamoon4 and aawisong. It was a sheer treat to watch them go up against the pros including notimesea and mmaxio, who have been around for quite a some time now. However, regardless of all their experience, it was dreamoon4, who emerged victor in the March Cook-Off 2014. And we are sure that our seasoned friends will be pleased to have some new competition. It all makes the coming Cook-Offs even more exciting as the fight back from the pros is due now. But for that we’ll have to wait. For now, let us come together and join our hands in appreciation of the top performers in our March Cook-Off 2014.
Firstly, the non-Indian top 10:

See you at the contests.
March, we would say is not the happiest time of the year. You can put it on the scorching sun outside, or can blame it on all the closings and examinations approaching. Whatever it is, it does not put March in the favorites list of many. However, contrary to many, we like March just as much as any other time of the year, for it marks our anniversary. Moreover, this year, we completed five years of code trotting, so it was special. We decided to celebrate it with you all through our t-shirt design and trivia contests. We got wonderful response for both of our contests, and we hope you all enjoyed them too. We were still not done with our anniversary celebrations, and we found ourselves confronting the March Challenge 2014. Although the preparations for the contest were all in place well beforehand, the final minute heebie-jeebies are always there. For that, we brushed ourselves up and headed towards the anniversary long challenge. Now, let us see how it was.
Our monthly long challenges have been a great platform for the fledgelings to display their flair. The March Challenge was no different either. The contest started with nine problems on the table, as the tenth one needed a tad more garnishing. The participants seemed contented with the nine problems in the offering and were seen munching on them joyfully. Most of the early goers into the contest enjoyed their calm Walk, while some other found joy in Team Split. Majority of the submissions made on the first day of the March Challenge 2014, were on the two previously mentioned problems, but they were not the only ones to find love in the opening day of the contest. As we moved into the contest, the submissions started flowing equally for all the problems. The Little chef and numbers, did not see many submissions in the early days, but received plethora of them as the contest progressed. And by the end of the contest the number of submissions was colossal.
While the lesser fancied were busy on the lighter end of the problem set, the big guns planned their move towards the top, battling the hard problems thrown at them, by our star studded panel of problem setters featuring Anudeep Nekkanti, Bruno Oliviera, Dmytro Berezin, Gerald Agapov, Konstantin Sokol, Sergey Nagin, Shiplu Hawlader, Tuan Anh, and Vivek Hamirwasia. It is worth mentioning that Anudeep Nekkanti, who made his debut as a CodeChef problem setter with this contest will also be representing India, with his team in the forthcoming ACM ICPC 2014 World Finals in Ekaterinburg. Let us give him a warm Welcome and best of luck for the World Finals. The testing of the problem set came from Mahbubul Hasan, while the Shang Jingbo penned down the editorials for them. The spices in the form of the Russian and Mandarin translation for the problems came from Gerald Agapov and Minako Kojima. These adroit individuals were and have been behind many delicious problem sets like this one. And we are always pleased to have them onboard.
The March Challenge did start with nine problems, but the tenth problem was added within couple of hours of start of the contest and since then it was all good until the final stages of the contest. That is when the few blank spaces in the test data of the problem The Street forced us to rejudge all the WA submissions. This was followed by the corrections made in the test data of the problem SSTORY towards the end of the contest and forcing yet another rejudge. No amount of apology can make up to the huge inconvenience caused to the participants in the final stages of the contest, and thus, with our apology we extended the contest by one more day. It means that the March Challenge was now of 11 days, and going by the response from the participants, it seemed a rather fair and fruitful decision. And the rightful conclusion to the contest.
Apart from the glitches towards the end, the March Challenge was a brilliant competition adorned by huge number of submissions, great competition, and some new names on the rank table. Among all the new names that made it to the final rank table, the ones that caught our attention the most were daiver19, dreamoon4, and aawisong. That is because all three of them were making their debut on CodeChef. Going by their debut, they very well can be the new crop of champions, which can threaten the reigns of our existing victors. However, that is all in the future and we cannot foresee what is in the store for us. However, what we can see is the rank tables for our March Challenge 2014, and the stars sparkling on that.
So, let us meet the stars. Firstly, the non-Indian top 10:
Then, our Indian top 20:
Now, we move on to the special achievers category. We will start with top three non-Indian and Indian users who have highest scores for challenge problem apart from the winners.

See you at the contests.
It was the ninth edition of our Lunchtime programming series. Just before the big examination season here in India. While students were deep into their preparations, we had just wrapped up ours, for the contest and were all set to put the young bright minds through yet another test. Although, it was the taste of the season, so we were enthusiastic about it as well. Moreover, we were all set to welcome the spring and the participants alike, with a big cooler.
The problem set for February Lunchtime 2014 came from Sergey Nagin, who also provided the Russian translations for the problems. Roman Rubanenko, who has been an imperative part of our Lunchtime series, handled the testing for the problems and like always, we were pleased to have him. The same goes for our Mandarin translator Minako Kojima and editorialist Constantin Sokol. With the impending exam season, our Lunchtime gave students a chance to break free from their study timetable, have some fun, and exercise their brains with some sharp challenging problems. Let us see how they did.
The February Lunchtime was pretty much like any other lunchtime we had, in terms of participation. However, the numbers kept growing as we moved into the contest. One department in which it differed from the previous iteration of Lunchtime was in terms of problem solving. Many participants successfully cracked three or more problems this time around. This meant that they were enjoying their stay in the contest to the fullest.
Despite the exam season, many Indian students were seeing trying their hands on the problems, and while there were some familiar names, we saw some new names in non-Indian as well as Indian rank tables. It is always good see some new names, popping up in the rank table amid the regular ones.
Now, let us introduce you to our little geniuses who made it through the final cut for our rank tables.
We will start with the non-Indian top 10, featuring:
And, the Indian top 10 featuring:
Now, the total stats for the contest:
Congratulations to all the participants for their brilliant performance.
The February Lunchtime 2014 started smoothly, in terms of both submissions and participation. However, there were some technical glitches towards the end of the contest, and as a result, we had to extend the contest by half an hour. It gave some more time to us and the participants alike to enjoy the contest.
Finally, after a small glitch, and some brilliant performance by the participants curtains came down on the February Challenge 2014, leaving behind, many memories, and some new names to look up to in the coming contests. And we will be looking up to each one of them. So make sure to join in our next contests.
With that we conclude this already delayed blog post on February Challenge 2014. We hope you will overlook the delay and enjoy it thoroughly. Although, if you have any suggestion, or feedback feel free to send them our ways at email@example.com
Till next time, TA-TA.
Concealed in the widespread span of February Challenge, the Cook-Off has had the stage all lit up for it. There were some requests regarding its rescheduling, but because of our fixed calendar, we were unable to take any of them. And, it turned out to be a wise decision. The problem set came from Shiplu Hawlader and Tasnim Imran Sunny, tested them. The detailed editorials for the contest came from Lalit Kundu. The Russian and Mandarin translations for the problems came from Gerald Agapov and Minako Kojima.
The Cook-Off came as a break free zone in the ten-day duration of the long challenge. The start of the Cook-Off was not very different from the long challenge as it too met a bump at the start. It was a kind of déjà vu for us, but not a pleasing one. We wanted to get out of it as soon as possible. Thankfully, we did get out of it in few minutes. The Cook-Off had some shades of the long challenge, be it the same set of translators, or the initial bump. While we cherished the former, we cannot say the same about the later. But, all’s well that ends well. And for us, the Cook-Off did end well.
The problem set for the Cook-off looked like a smooth sail at the beginning of the contest. However, that changed by the time the contest got over. There were only three contestants, who cracked all of the five problems during the contest, and they were our top three. The competition among the top three was furious and it was only after the contest we met our winner. While, the top of the table presented a familiar sight, with surprise entry in dj3500, the bottom half of the table was adorned by the big three from India, the knsn, djdolls, and anudeep2011. A pleasing sight it was, and we hope to see it more often.
To let you know, who stands where in the rank table? Let us take you through it:
Now our Indian Top Five:
Here are the final stats of the contest:
Sincere congratulation to everyone for their brilliant performance and all the best for the future contests.
With that, we reach to the end of our long stretched February blog post covering the long challenge and the cook-off in one. We know it took us too long to put up this post, and we are sorry about it. We hope to better our frequency of blog posts covering our contest and to bring you all the updates from CodeChef’s kitchen as and when they happen.
Now, we move towards the pending February Lunchtime post, with all the details of the performance of our little geniuses. So, keep watching this space. In the meantime, send us your feedback, suggestions, and queries, to firstname.lastname@example.org.
Till next time, it is TA-TA from CodeChef
See you at the contests.
The February Challenge was a special one even before it started, for it concealed our February Cook-Off 2014 during its ten days. The occurrence of two events in the course of one meant twice the fun, excitement, and work. We will try to share all the memorable moments with you from our memories.
February, the shortest month of the year, seems big with all those pre-exam season jitters and apprehension regarding the format of the question papers. Thankfully, none of those can be associated with our monthly contests. We started on the first Friday of the month and had 10 problems, like always. It became 11 by the end of the competition, but we will come to that, later. The problem-setting panel this time around featured two debutants in Shiplu Hawlader and Lalit Kundu. Both of them were greeted warmly, if the number of submissions on their problems is to be believed. Accompanying the debutants on the problem setting bench were Dima Berez, Ivan Zdomsky, Minako Kojima who also was the Mandarin translator, Roman Furko, Sergey Nagin, Surya Kiran, and Vitaliy Herasymiv. Gerald Agapov and Hiroto tested the problems, with Gerald doubling as the Russian translator as well, while the editorials came from Ajay Kumar Verma. The month long hardwork of all these geniuses was put to test in our February Challenge. Let us find out what was the outcome.
The contest opened to a warm reception, the impending examination season seemed to have very little affect on the participants. And we’d like to believe that you all were well prepared. Longest Common Pattern, and Little Elephant and Subarrays, received all the love in the initial stage, but the love reached to other problems as the challenge progressed. After the calm and smooth start, we hit a minor hiccup as some of you were facing connectivity issue. Although it was not a long-drawn-out problem, but it still caused problems and we apologize for that. Following the technical wallop, we bumped into another, as we came to know that the problem LMATRIX is very similar to one another problem that had been used in our contest earlier. We took this issue to the problem setter and they agreed to it and decided to replace the problem with another on in LMATRIX2. We were upset about the entire episode as much as you all were. We deeply regret the inconvenience. Without losing any more precious time, we stopped all the submissions to the problem and added another problem LMATRIX2 in its place. In order to repair the damage caused by LMATRIX, we eliminated all the submissions made on LMATRIX and adjusted the ranks to not reflect them. While, it cannot redo the damage caused to the integrity of the contest and its problems, we like to believe that it was an honest mistake. Still, we are sorry about it. And will look to it that such “mistakes” do not take place in future.
After the blotchy opening two days, the contest resumed its natural course in its full glory. All the big guns had made their presence felt on the rank tables, and were facing tough fight from the emerging champions. And we must say that it was quite a treat to witness such great competition. In a contest were users from different part of the world were going up against each other to emerge triumphant, it was the Chinese coders who dominated the rank table. Among the top ten participants, we had eight users from China. However, our top three all had different nationalities. Now, without getting into the nationalities, here is how the rank table looked at the end of the contest.
Non-Indian Top Ten:
Indian Top Twenty:
Now, we move on to our special achievers category.
We’ll start with “Users with highest scores in Challenge problem other than the winners”:
Now our geniuses from school:

Despite the bumpy start, the February Challenge 2014 fared out to be a fine contest for everyone who participated in it. And off course for us, as we saw some fine performance, by some new names and some existing ones. Thanks to all you wonderful people for giving us yet another exciting contest.
With that, we conclude the post and say farewell to you. Now, let us set our sails towards the February Cook-Off 2014 and take you through it, as it happened.
