A bit hot April LunchTime 2015

2 min read

There is something about the academic year that brings gamut of mixed emotions in the students. While euphoria of exam end elates the fun of summer vacations, the realization of end of yet another year filled with fun and mischievousness with your pals adds a tad wretchedness to the atmosphere. And there are those summer project works that although always gets procrastinated to the last days of the vacations, but never fully gone from the summer plans. All that makes up for a rather packed summer, so it actually becomes rather tough to squeeze in another activity. But not if you are a programming fanatic. Programmers always manage to add an enticing programming contest into their planners, no matter how packed it is. We know that, because you all joined us for our April LunchTime 2015. And we are sure you would have enjoyed it too. So, let’s see how the 3 hours of April LunchTime went.

The dose of excitement for April LunchTime came from the problem set of Sergey Kulik, who also contributed their Russian translations. The Mandarin versions, as always came from Minako Kojima. And although the contest saw its first submission inside the five minutes, the problems made the participants fight hard for their ACs all through the contest. And our tester Karan Aggarwal had ensured that they did. However, the participants found some solace in TICKETS5, which saw the maximum submissions for the contest right from the beginning. As a matter of fact, it was the first problem solved by most of you.

And after “Tickets” the submissions started flowing towards House Cleaning, however, the flow was a tad slow. And the first one to crack it was anta0, followed by yutaka1999. The story remained the same for Euler Totient Function Extended and Palindromeness with submissions coming in but not at the same pace. Even the result codes for the submissions started varying, while it was AC for most in the beginning, we started seeing more of TLEs, WAs and many others. It resulted in lots of tumbling and toppling in the rank tables with name of schools and students changing in the list. And to tell you who stood where when the contest ended, let us take you to our rank tables.
