Unofficial Div 4 Round #2

Revision en8, by mesanu, 2020-11-25 21:21:09

Hello Codeforces!

SlavicG and I are glad to invite you to Unofficial Div 4 Round #2. Which will take place this Wednesday at 14:35 UTC (The round is over now, but you can still participate virtually). The round will not be rated for any participants since it is unofficial. You can find the contest on the gym section of codeforces.

You will be given six 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 want to thank everyone who was involved in the round preparation:

Errichto for thorough testing and publishing this round on the gym.

Also, after the contest Errichto will post videos about this contest and the responsibilities of a tester.

Brodicico for help with problems and testing the round.

And a huge thank you to the testers: Errichto, Monogon, galen_colin, gupta_samarth, arujbansal, Chihai_Ion and Grumpah .

MikeMirzayanov for Polygon and Codeforces platforms.

Even though the contest is unrated, we believe it is an excellent way of practice, especially for Div 4 users.

Remember, if you don't know how to solve one problem, look at others!
