We are glad to invite you to take part in Codeforces Round #568 (Div. 2), which will be held on Jun/19/2019 17:45 (Moscow time). The round will consist of 7 problems (possibly, plus subproblems). It will be rated for Div. 2 participants.
We, geranazavr555 and cannor147, are students of ITMO University. And we have recently joined the developers team of Codeforces and Polygon. We have prepared this round for more careful acquaintance with the system. We hope that you will enjoy the competition.
Initially, we had prepared the round for Div. 3, but after testing, it became clear that this round is harder than usual such rounds. MikeMirzayanov suggested to make this to be rated for the second division.
Many thanks to MikeMirzayanov for the tremendous work on the creation and development of Codeforces and Polygon and coordinating our work. Also, special thanks to Vshining, PikMike, ZeroAmbition, Vovuh, Lewin, Dave11ar, T-D-K and Azat_Yusupov for testing the round.
The scoring distribution will be: 500 — 1000 — (1000 + 750) — 2000 — 2250 — 2750 — (2750 + 750). The round will last 2 hours and 15 minutes.
Congratulations to the winners:
