Unofficial Div 4 Round #2

Revision en10, by mesanu, 2020-11-26 22:43:09

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.

Contest link: https://codeforces.me/gym/102873

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.

UPD: Videos are now up: Fixing A, Testing A, Testing the rest.

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!
