Revision en9, by Dalgerok, 2019-04-18 21:25:53

Hi, Codeforces!

Codeforces Round #553 (Div. 2) will be held on 18.04.2019 18:35 (Московское время). Round will be rated for second division (rating below 2100). As usual, participants from the first division can participate in the contest out of competition.

My gratitude to arsijo and KAN for coordinating the round, Markellonchik (special thanks for the help in preparing one of the tasks), mohammedehab2002, Jeel_Vaishnav for testing, and also 300iq for the idea and preparation of one of the tasks, Aleks5d and isaf27 for testing it, and of course MikeMirzayanov for Codeforces and Polygon systems.

In this round you will help the residents of the Kingdom of Kremland. I strongly recommend you to read the statements of ALL tasks (and of course, try to solve them).

Good luck!

UPD: Scoring distribution: 500-750-1250-1750-2250-2750.
