Hello Codeforces!
mesanu and I are glad to invite you to Unofficial Div 4 Round #1, which will take place on Sunday, September 20, 2020 at 17:35. The round will not be rated for any participants since it is unofficial. You can find the round in the Gym section of Codeforces.
You will be given five tasks and two hours to solve them.The problems were created and prepared by mesanu and SlavicG for users with a rating range from 0 to 1400 but anyone is welcome to participate in the round!
We would like to thank everyone who was involved in the round preparation:
- FLEA for round coordination.
- Brodicico, Grumpah, Sho, FLEA for testing the problems and providing useful feedback.
- MikeMirzayanov for Polygon and Codeforces platforms.
We tried our best to keep the statements short and clear and we hope you will like our problems!
