Hello, Codeforces! Today there was the second stage of the Republican Olympiad in Informatics in Mogilev region (Belarus). And I, as the author of this contest, decided to share this contest with you.

I have posted this contest in the gym by the link: https://mirror.codeforces.com/gym/103464

Contest rules: contest has 4 tasks for 5 hours, and it has IOI format, i.e., scores and subgroups. As for the difficulty of the contest, I think it will be interesting for people with a rating of 2000 and below, because the most difficult problem in it is not above the level of D2D — D2E.
