Hello!↵

I'm glad to invite you all to Round 576 which will take place on [contest_time:1198].↵

There will be 6 problem in both divisions.↵

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: [user:Um_nik,2019-07-29], [user:Burunduk1,2019-07-29], [user:I_love_fake123,2019-07-29], [user:MakArtKar,2019-07-29], [user:Villen3tenmerth,2019-07-29], [user:Aphanasiy,2019-07-29], [user:Gadget,2019-07-29]. One of the problems is authored by [user:Merkurev,2019-07-29] (just because we are friends :) ). One more problem for the round was added by [user:KAN,2019-07-29].↵

I would like to thank [user:KAN,2019-07-29] for CF round coordination, [user:I_love_Tanya_Romanova,2019-07-29], [user:Merkurev,2019-07-29], [user:Rox,2019-07-29] and [user:tractor74.ru,2019-07-29] for testing, and Codeforces and Polygon team for these beautiful platforms.↵

Scoring will be announced.↵

Upd: We added one more problem to div.1 contest, now both contests have 6 problems (4 in common). The round is not combined, if it were, I would write "combined" in the title.↵
