Tomorrow, at 10:00 Moscow time will be held Round 1 of Yandex.Algorithm competition, authored by me. I would like to thank Zlobober for all the job he does to make this competition interesting, MikeMirzayanov for the great polygon that ease the preparation process a lot, and everyone, who tested the round and made useful comments. Of course, we did our best to make the problem diverse by topics and difficulty.
See you in the competition dashboard!
UPD Thanks to everyone who participated, hope each of you found at least one interesting problem. We apologize for the situation with problem F, we have googled for all the problems and asked all testers whether they have seen such problems or not, but that didn't helped. The editorial has been published.
