We are glad to invite everyone to participate in Codeforces Round #773 (Div. 1) and Codeforces Round #773 (Div. 2), which will be held on Feb/23/2022 13:10 (Moscow time). Notice the unusual time! The round will be rated for both divisions. Each division will have 6 problems, and you will have 2 hours to solve them. We recommend you read all the problems!
