Hello, Codeforces! (or as we say in romanian, "Nu renunţ la tine niciodată")

I am glad to invite everyone to participate in Codeforces Round 833 (Div. 2), which will be held on Nov/12/2022 17:35 (Moscow time).

This round will be rated for all participants with rating lower than 2100.

You will be given 6 problems and 2 hours to solve them. All of the problems are authored by me.

I would like to thank the following people, without whom this round would not have been possible:

• IgorI for his awesome coordination of the round and for helping me with problem preparation.
• feecle6418, Gary2005, RUSH_D_CAT, atodo, BucketPotato, andrei_boaca, hochesh, JohnVictor, valeriu, powergee101, jampm, alin_gb18, sutekine, tibinyte and ansergeyg for testing the round and providing valuable feedback.
• MikeMirzayanov for the great systems Codeforces and Polygon.

Here is the scoring distribution: $$$500−1000−1500−2000−2250-2750$$$

Good luck & have fun!
