Hello Codeforces!

The series of Educational Rounds continues thanks to the support of the Neapolis University Pafos.

Educational Codeforces Round 195 (Rated for Div. 2) will start on Oct/14/2026 17:35 (Moscow time).

This round will be rated for the participants with rating lower than 2100. It will be held on extended ICPC rules. The penalty for each incorrect submission until the submission with a full solution is 10 minutes. After the end of the contest, you will have 12 hours to hack any solution you want. You will have access to copy any solution and test it locally.

You will be given 7 problems and 2 hours to solve them. I hope everyone participating finds interesting problems for them to solve.

The round is based on the problems from The ICPC Southern and Volga Russia Regional Contest. If you participated in the Qualification Stage, please refrain from taking part in this round.

The problems were prepared by fcspartakm, Roms and me.

I would like to express my gratitude to Mike MikeMirzayanov Mirzayanov for creating Codeforces and Polygon, two platforms which made conducting programming contests and preparing problems for them much more convenient. Also big thanks to testers: awoo, FelixArg.
