Hello everyone!

Codeforces Round #315 will take place soon. The authors of this round are students of Ural FU sivukhin and Um_nik. This is our second round. First one was in the black days of Codeforces and we hope that this will not happen again after our round :)

We want to thank Codeforces team for great Codeforces and Polygon platforms and Zlobober for helping us prepare this round.

Score distribution will be posted later. We'll do our best to post it as early as we can.

Good luck!
