The March Lunchtime 2016 was the second Lunchtime away from the lunchtime; the 1st being the February Lunchtime. The March Lunchtime had a rather colorful backdrop, for it came quickly after Holi. The kids were still high on sweets, colors, and mischief, and no amount of exam scare was going to suppress it. Then, who are we to do so? So, we decided to join them and raise the fun levels a tad more, by giving away 2X more laddus to all the participants. It was our attempt to sweeten the Holi for you all and give you something more to cheer ahead of the busy exam season. So, did the 2X laddus do any magic? Let’s find out.
The sweet-sweet problem set from the March Lunchtime came from the Sergey Kulik, who by now has developed a reputation among the Lunchtime participants for his tricky problems. And let’s just say, he lived up to that. The testing for his problems was done by Vlad Mosko, who was making his comeback to the Lunchtime panel after July Lunchtime 2016. The coming together of a seasoned campaigner and a returning tester presented the participants with some delectable problems in Simple Statistics, ABABAABA, Two Closest, and Arrays Sum. However, the stats column suggested otherwise. So, we leave it up to you. What did you thought of the problems from the contest? Were they cut out for you, or you found them a tad sour for your taste? Do send your feedback to us at: firstname.lastname@example.org
Now, to the young geniuses who came and tried their hands on the problem set, let’s see how they did. While others were having trouble finding their way across the problems, nano_ape seemed like taking a stroll down the park. A slow one though. He made his first submission after 15 minutes into the contest and viola it was an AC. The same result appeared for his 2nd, 3rd, and 4th submissions as well. The time interval between them, kept on increasing, but the result for all of them remained the same. And with all four problems cracked into his kitty, he secured the top spot on the rank table. On the very close second was kmcode, who unlike nano_ape made a lot of submissions getting varying result codes to secure the second spot. And on third position we had our Indian lad, mbrc. With 16 point difference between kmcode and mbrc, it was a close shave for the second place on the rank table. The two gentlemen gave their everything, literally till the very last minute of the contest, when at 10:29 PM mbrc got his final AC.
The competition for any other place on the rank table was no different. One look at the March Lunchtime rank list and it will become rather apparent to you.
And while we are at it, let us introduce you to our winners for LTIME34.
We start with the ROW top 10:
Now, the Indian top 10:
Congratulations to you and to everyone who joined us for LTIME34.
The stats for LTIME34 might not compare well to some of the other Lunchtimes we have had here on CodeChef, but we know once the exam season passes, we certainly will have those numbers go up a notch. For now, here are the final stats for the contest:
Now, before we move forward let us thank the other members of the problem setting panel including our editorialist Pushkar Mishra, the Russian translator Sergey Kulik, our Vietnamese translators Team VNOI, contest admin duo of Praveen Dhinwa & Pushkar Mishra, and Mandarin Translator Hu Zecong. None of this would have been possible without these fine gentlemen. And now, it’s editorial time. So, before we take your leave, let us take you through the editorials from our March LunchTime 2016.
That is all that we have for you from the March Lunchtime 2016, if you think we missed any aspect the contest or your favorite bit of the contest, feel free to reach us at: email@example.com

Till next time, adios.
See you at the contests.
We could have called it March madness, had there been any madness. We could have called it March melody, had there been any rhythm. The madness, the melody, and all things fun associated with March had taken a back seat by the time we reached to March Cook-off 2016. The only thing prevailing was the imminent exam season, the last minute rush to wrap up the papers, the practical files, and to kick start the preps for the final exams. There’s something about engineers and their love for the last minute haste, which somehow never ceases to amaze. It was the same story in the second half of the March. But a true engineer always manages to accomplish all things important. And hence we weren’t bothered about the participation in the March Cook-Off 2016. The hanging time-tables on the notice boards, did dip the numbers a tad, but they were still pretty to look at. And hence before we move into the post, let us present you the numbers from our COOK68.
We finished the contest with 1286 users, almost equally from and outside India. We are sure each one of you enjoyed the problems of Jakub Safin, especially the Alternating Subarray prefix and Digital clock. They both ended up being the most popular problems from the contest in terms of ACs, with Digital clock having a higher accuracy rate of 69.06. Now, isn’t it interesting that the easiest problem troubled the participants more than the second easiest? But then, that’s the fun you get in these short contests.
The story wasn’t drastically different for the harder problems as well. And the Not even planar and the potato problem troubled the participants almost equally, with the former turning out to the hardest of them all. In the middle of the difficulty spectrum was the Dual Nim, with 294 submissions against it. Overall, the problem set was nicely balanced and well tested, thanks to Vasya Antoniuk.
A balanced problem set also means stern competition for the places on the rank table and we got exactly that, with the arrival of uwi in the third minute of the contest. Joining the rank table before him included the likes of hellkitsune, alex_2oo8, fataleagle, and Fdg, who eventually joined him on the podium. In them and few other familiar names, we had our probable winners battling it out. And we thoroughly enjoyed it. With them making an early appearance, there was not a single dull moment into the contest. And we hope it was the same for you as well.
Now, before we move further, let us meet the winners of our CodeChef March Cook-Off 2016:
We start with the ROW top 10:
Now, the Indian top 5:
A huge round of applause for all our winners, and for all you wonderful people who successfully squeezed the COOK68 into their packed March calendars!!!
Before we move forward into this delayed and curtailed tale of March Cook-off 2016, it’s only fair to thank the other gentlemen on our problem setting panel. We start with Rahul Arora, who verified the language of the problem statement; Hu Zecong, the Mandarin translator; Team VNOI, the Vietnamese translator; and finally our admin and editorialist for the contest, Praveen Dhinwa. Thank you gentlemen for all your hard work and time for cooking up the contest, we hope to continue receiving the same for all our future contests.
That brings us to the final segment of the post. We know that not everyone who joins the contest ends up on the rank table. And that is absolutely fine, as long as you are ready to shed the disappointment behind and are ready to move forward with more determination and gusto. We are always by your side and there to help you in any possible manner we can. For now, let us take you to the editorials for the March Cook-off 2016, which we think not only will help you get over the doubts you might have regarding any of the problem from the contest, but also will teach you a thing or two new about competitive programming in general. So, devour them:
That brings us to the final segment of the post. We hope you enjoyed it as much as you enjoyed the contest. However, if you have any concerns or queries regarding the post, the contest, or the CodeChef just in general kindly do write to us at: firstname.lastname@example.org
We will be back soon with the tale from the final contest of March, the March Lunchtime 2016.
Till then, keep coding.
See you at the contests.
March Challenge 2016 was an extension of our anniversary celebration. And joining us in our celebration were our problem setters in Praveen Dhinwa, Prateek Gupta, Sunny Aggarwal, Malvika Raj Joshi, Maksym Bevza, Sergey Nagin, Roman Furko, who also did the testing for the contest as well, and Vasya Antoniuk. Alongside testers Kevin Charles Atienza and Roman, editorialist Kevin Charles Atienza, translators Vasya Antoniuk (Russian), Team VNOI (Vietnamese) & Hu Zecong (Mandarin), language Verifier Rahul Arora, and our ubiquitous contest admin Praveen Dhinwa too were there.
If you know CodeChef, you would have heard almost all the aforementioned names. They have been seen on rank list, discussion forum, problem setting panel, and where not. However, we had a very special debutant there in Malvika Raj Joshi. A prominent name in the programming fraternity, this was the first time Malvika was joining the contest as the problem setter with an easy and a hard problem. In doing so, she also became the youngest problem setter on CodeChef. Setting up and breaking records seems just right up her alley. If you think you can challenge that record, we would love to have you on our problem setting panel. So, don’t hold yourself back head over to our problem setting guidelines and find out more about it.
From the problem setters to the problems, let’s see how you fared. In pursue of laddus, plethora of early birds joined in the contest and started crunching solutions to the problem best suited to their tastes. However, it was Sunny’s Palindromic substrings that got things going on for them. After the first AC from z_programmist, the result code AC just kept going up against this problem. The scenes were in quite contrast against Roman’s Polygon & Circles. Even after numerous attempts not many were able to get past it. The same was the case with Malvika’s Tiptoe through the tulips. But with 24 and 31 ACs respectively against the said two problems we think that the problem set was nicely balanced.
While, the problem set was giving a gamut of emotions to the participants, the tension was building atop the rank table with every AC. Among the top contenders for the top slot were mugurelionut, ACRush, djdolls, ceilks, kutengine, and the new sensations rns_kjch, kut_pcj1995, and kut_boy1995. At one point it was really tough to put your finger on one. In fact it remained that way till the very last day of the contest. And then there was the late addition of test cases in CHEFSPL, resulting in one day extension of the contest. It made us wait for one more day to find out the winners. Finally, on the 11th we got our winner in mugurelionut. The route atop the rank list wasn’t easy for mugurelionut with some serious challenge from his old pal kutengine. And we are sure both of them would have enjoyed each others’ company on the rank table. Now, to meet everyone who joined them atop rank table, let’s go through the rank list once.
We start with the ladies. After a long time, we have Top 5 women participants. So, give a huge round of applause for them:
Now, we move towards the men. The ROW top 10:

With that, we draw curtains on this post and set up stage for March Cook-Off 2016. We will come soon with the tale of the short March Cook-Off soon. Till then, keep the submissions flowing in and keep participating.
Till next time, adios.
See you at the contests.
1st of April, notoriously known as “All Fool’s Day” is one day of the year dedicated to playing non-hazardous pranks and spreading hoaxes.
We at CodeChef, are a team of pranksters. It won’t be an exaggeration to say that quite often we spend days to plan our next prank and spend well thought out hours to execute them on our team members. In continuing with our traits, we had played a prank some 6 years ago on our users that did not go too well with them (please read the comments and subsequent explanations given by admins).
Once bitten, twice shy, we were forced to cut down on our prank instincts to never take it up again. However, this year, the itch finally gave in and we decided to have a much more subtle version of April Fool’s Day prank including you all. We exist because you do and hence you needed to be a part of our party.
Don’t recall how and when were you pranked? Well, let us tell you.
Remember the “submit” button that you were chasing a little while ago? Well, that was it. You must have been thinking “Oh, I thought it was only me”, or if you thought it was yet another CodeChefs’ bug, it wasn’t. Happy April Fool’s Day!
Do you want to see how you looked chasing that submit button? Yes, we have a screen capture that we want to share with you. So, check it and have a good chortle.
We have stopped the prank now. So, if you are still chasing that submit button, you must stop, take some sleep, have a cold shower, and may be a walk in the park; because it’s not happening anymore.
We hope you did not mind this little fun that we had at your expense. It was all done in good spirit. Do share some of the wonderful pranks that you pulled on your pals with us and maybe we can use some of them next year.
Till then, enjoy the contest.
