Hello Codeforces!
I'm excited to invite you to Weekend Practice round #13 , taking place on 9th November, at 10:00 UTC. This is a rated contest at Eolymp.
Format and Difficulty
Same as in previous rounds, the competition is primarily aimed at improving practical skills. There will be $$$2.5$$$ 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.
One of the problems will be interactive so please make sure to be familiar with them.
