Hello Codeforces!↵
↵
The series of Educational Rounds continues thanks to the support of the [Neapolis University Pafos](https://www.nup.ac.cy/bsc-in-computer-science-and-artificial-intelligence).↵
↵
On [contest_time:2225] [contest:2225] will start.↵
↵
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 **6 or 7 problems** and **2 hours** to solve them.↵
↵
**This round is based on problems from the 2026 Tula Open Programming Championship.**↵
↵
The problems were invented and prepared by [user:basalov_yurij,2026-04-16], [user:BledDest,2026-04-16] and me.↵
↵
I would also like to thank the other problem authors of the championship: [user:ashmelev,2026-04-16], [user:Galina_Basalova,2026-04-16], [user:Rudom71,2026-04-16] and [user:my-maxi-box,2026-04-16]. Thank you, it is a pleasure working with you!↵
↵
Many thanks to the round coordinator, Ivan [user:BledDest,2026-04-16] Androsov, for improving the quality of the problems and helping with their preparation.↵
↵
