Ladies and Gentlemen!
The Codeforces round #359 for both divisions will happen on 23 June at 7:35 PM MSK. We have been choosing and solving problems for a long time and we hope that they will seem quite interesting.
All of the problems were created under guidance of Endagorion (Mikhail Tikhomirov) by Moscow high school graduates: cdkrot (Dmitry Sayutin), ch_egor (Egor Chunaev), themikemikovi4 (Mikhail Sorokin) and me. It is our second Codeforces Div.1 + Div.2 round.
Thanks to coordinator GlebsHP (Gleb Evstropov) for help with preparing problems and to MikeMirzayanov (Mikhail Mirzayanov) for excellent systems Polygon and Codeforces. Also, the round is possible only because of Endagorion's help.
Participants will be given five problems in both divisions. The scoring distribution will be announced later.
Good luck to all!
