Hello, Codeforces!

I would like to invite you all to the call for tasks for APIO 2025. This year's edition will be hosted by Uzbekistan.

APIO 2025 needs tasks of various difficulties so we encourage all to submit tasks of any difficulties. Each task that's actually used in the contest will be rewarded with USD 400 after the end of the event.

Details of the task submission process are available here: https://apio2025.uz/call-for-tasks.

The deadline for task submission is April 20, 2025.

Looking forward to your interesting problems!
