Hi Codeforces!
We are happy to invite you to take part in Codeforces Round 561 (Div. 2). The contest will be held on 17.05.2019 18:05 (Московское время).
You will be given 6 problems and 2 hours to solve them. The round will be rated for all contestants with rating below 2100. As usual, participants from the first division are welcome to join out of competition.
The problems were written and prepared by Jefe and me. We owe a huge thanks to KAN for coordinating the round, to Lewin and mohammedehab2002 for testing, and of course, to MikeMirzayanov for the great Codeforces and Polygon platforms.
Good luck and have fun!
UPD: A huge thanks to neal, dreamoon_love_AA, and antguz for help with additional testing.
