Hello Codeforces!

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

Educational Codeforces Round 194 (Rated for Div. 2) will start on Sep/08/2026 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.

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, more testers will appear soon.

Our friends at Neapolis University Pafos have a message for you:

Planning to apply for the Computer Science and Artificial Intelligence (CSAI) program at Neapolis University Pafos?

JetBrains Youth Clubs can help you prepare.

🤖 AI Club is a chance to explore one of the core areas you’ll study in the CSAI program. You’ll work with AI topics, strengthen your understanding, and get more experience before university.

➗ Math Club helps you sharpen the mathematical problem-solving skills you’ll need for the program. There’s also a direct application benefit: participation in the Math Club can give you 30% of your entrance test mark for the Computer Science and Artificial Intelligence BSc supported by JetBrains Foundation.

Both clubs are designed for high school students with a strong interest in STEM who want to challenge themselves and prepare for the next step.
