After two big contests in September Challenge & Cook-Off, the wait for September LunchTime 2016 seemed like eons. You already know how eager we get when it comes to our LunchTime contests. After all, who wouldn’t want to see the young programmers from schools battling it out on a fine Saturday evening? To notch that all up a bit, we had the registrations going on for the upcoming ACM ICPC 2016 – 2017 India regionals, which meant the competition was already on among the aspiring teams to better each other. It just gave us one more reason to look forward to LunchTime. So, we cleared our Saturday evening calendar and kept it all for September LunchTime 2016.
The problem set for the contest came from Misha Chorniy and was tested by Sergey Kulik, accompanying them on the problem setting panel were Pawel Kacprzak, Praveen Dhinwa, Team VNOI, and Hu Zecong, all donning different roles. For every contest we expect a nicely balanced problem set, however, this time around the problems were on exact opposite ends of the difficulty level. While the easiest of them all Chef and Inequality saw over 900 successful submissions, Chef and Words, which turned to be hardest among the four, saw only 8 submissions. Even the situation for the remaining two was pretty identical with 19 and 9 submissions for Chef and Tree and Chef and Triangles respectively.
On the rank table though, the battle was as fierce as ever. And even the start of the contest was pretty good with plenty of ACs in the first half an hour. Most of them though, were on Chef and Inequality, but that is normal and we have seen in many of our contests where most of the submissions in the early stages of the contest come on one single problem only. The first one to taste the sweet nectar of AC was anta0 and it took him only a minute to get that. Soon to follow him were zscoder, nuip, vladik, iman_gh and many others with their ACs on Chef and Inequality. In the first 5 participants to have received an AC, we had two from schools. So, with that, the battle among the school students was on. No, Indian school student was able to make an appearance in the first 50 submissions into the contest. And that was a tad surprising.
While the absence of Indian school students was a bit surprising, the battle between zscoder, kmcode, and austin990301 made up for that. None of the three however, were able to crack all four problems and that affirmed the tough nature of the problems. And to find out who emerged victorious after battling with the problems till the very end, let us take you to the rank table of our September Challenge 2016.
