صباحو (Good Morning), Codeforces!
I'm glad to invite you to Codeforces Round 746 (Div. 2), which will be held on Oct/03/2021 17:35 (Moscow time).
This round is rated for the participants with rating lower than 2100.
You will be given 6 problems and 2 hours to solve them. All problems were prepared by me and Bakry.
One of the problems will be interactive. So, it is recommended to read the guide on interactive problems before the round.
I would like to thank:
