Codeforces Round #490 (Div. 3) Editorial

Revision en6, by vovuh, 2018-06-22 22:13:50

I'm really sorry for the issue with the problem D difficulty, it was much harder than i expected, and there was a big difficulty gap between problems C and D. I hope in the next rounds it will never happen again.

UPD: I'd like to say a big thanks to kevinsogo for the great help with tutorials and the round preparation in general.
