I'm glad to invite you all to Round 576 which will take place on Tuesday, July 30 at 17:35 UTC+3.
There will be 6 problem in division 2 and 5 problems in division 1.
Round is based on Team Olympiad in Computer Science Summer School. It is (yet another) summer school for schoolchildren organized by Higher School of Economics and "Strategy" Center in Lipetsk. Almost all the problems are authored and prepared by teachers and teaching assistants in CSSS: Um_nik, Burunduk1, I_love_fake123, MakArtKar, Villen3tenmerth, Aphanasiy, Gadget. One of the problems is authored by Merkurev (just because we are friends :) ). One more problem for the round was added by KAN.
Scoring will be announced.
