Hello Codeforces!

MathModel Setting Tour Continues!
I'm glad to share my tour of problem-setting with you! Recently, I have been setting problems for multiple platforms such as CodeForces Gym, CodeChef, KEP and RoboContest !, and more is coming $$$!$$$

We are excited to announce a new Weekend Practice round #5 on March 16, at 16 UTC. This is a rated competition at Eolymp.

Format and Difficulty

Same as in previous rounds, the competition is primarily aimed at improving practical skills. There will be 2 hours for 5 tasks of varying difficulty, the easiest of which can even be solved by beginners.

The scoring for each task being block-based (meaning points are awarded for each block of tests separately, and only if the solution passes all tests in the block). If there is a tie between two participants, the one whose last productive submission (i.e., a submission that added at least one point) was made earlier will be ranked higher in the leaderboard.

The statements will be available in the following languages: English, Ukrainian, French, Spanish, Azerbaijani, Russian , Arabic , Turkish and Uzbek.
