Revision en3, by send_nodes, 2016-09-11 00:46:12

Hi everyone. I'm trashfirstsearch, and I used to be blue...

Anyways, Codeforces Round #370 (Div. 2) will take place on 10 September 2016 at 19:35 MSK. As usual, Div.1 participants can join out of competition.

Much thanks to GlebsHP for helping me with preparing the contest, MikeMirzayanov for the Codeforces and Polygon platforms, and minimario and MCSPVMTT for testing problems.

This will be my first contest prepared on Codeforces, and I have prepared all the problems with the intent of making them interesting for everyone. It is, as usual, strongly advised to read all the problems.

Good luck, and I hope you will gain rating(and force someone else to lose it >:) ).

Update: Congratulations to the winners:


  1. KrK

  2. halyavin

  3. fhlasek

  4. gritukan

  5. Kmcode

Here is the editorial.

I sincerely apologize for the problems during the contest. However, I hope everyone found the problems interesting! Thanks to everyone who participated and helped with the problems!
