Hello Codeforces!
I'm very super duper ultra excited to invite you to the first round I have written on my own, Weekend Practice round #6 , taking place on May 11, at 12:30 UTC. This is a rated contest at Eolymp.
At the same time, The Team Selection Test for the Palestinian Team for IOI 2025 will be taking place in a private mirror, and is open for potential participants .
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.
Registration
