Hello, Codeforces!

T4M0FEY, qualdoom and I are glad to invite everyone to participate in Codeforces Round #846 (Div. 2), which will take place in Jan/25/2023 17:35 (Moscow time).

This round will be rated for the participants with rating lower than 0x834 (i.e. 2100). Participants with a higher rating can take part in the round unofficially.

You will have 7 tasks and 2 hours to solve them.

One of the problems will be interactive. Make sure to read this blog and familiarize yourself with these types of problems before the round!

I want to sincerely thank everyone who provided invaluable help in preparing the round and made it many times better:

This is our first official round on Codeforces. We sincerely hope to your participation. We hope that you will like the proposed tasks!

The score will be announced closer to the start of the round.

We wish you good luck and have a good time! See you in the round!
