Codeforces Round #520

Revision en3, by JATC, 2018-11-12 20:42:02

Hi everyone. I'm glad to announce that the Codeforces Round 520 (Div. 2) will be held on Nov/14/2018 18:35 (Moscow time).

The round will be rated for Div 2 participants (whose rating lower than 2100). However, all the other participants can compete as well, without worrying about ratings being changed.

You will be given 2 hours to solve 6 problems. It's better to read all the problems. The scoring distribution will be announced soon before the contest starts.

All the problems were prepared by myself, with some help from my friend — GiraffeCoder. I want to thank cdkrot for coordinating me in preparing the problems. I also want to thank csacademy for their graph editor tool. You can check it out at this link.
