Hello Codeforces!

I am glad to invite you to InfOJ April Fools Day Contest 2025 which will start on April 5th 2025, 19:00 UTC+8.

The contest will last for 2.5 hours with 10 tasks for you to solve. All problems are worth 100 points, and the contest will be in IOI mode.

Since 2021, infoj has held four editions of the April Fool's Contest. Each year, we uphold the mission of "expanding the boundaries of the online judging system" and present freshly eye-opening problems to a wide range of participants, both with and without competitive programming background.
