Hello, Codeforces Community!

We are thrilled to invite you to participate in the Khulna Regional Inter University Programming Contest (KRIUPC) (Online Mirror) on Codeforces! The main contest will take place on Nov/10/2024 11:00 (Moscow time) for a duration of 4 hours, and will be held on toph.co. The mirror contest will follow shortly after the main event.

This contest follows ICPC-style rules and is unrated. Team participation is recommended, but individual participation is also allowed.

As the coordinator, I’ve had the privilege of working alongside an amazing team to bring this contest to life, and we’re excited to see your skills in action!

Acknowledgments:

• Special thanks to MikeMirzayanov for the powerful Codeforces and Polygon platforms.
• The problems were set by steinum, AST_TheCoder, purple_ghost, RakibulRanak, RD_TheCoder, and _r4m1m.
• Appreciation to our testers: Alfeh, Ryuga_, nh_nayeem, jamil314, t17, border, and ItsHABIBA for their thorough testing.

We kindly ask participants who are already familiar with the problems to refrain from participating or discussing them before the contest ends.

We hope you enjoy the problem set, and best of luck to all participants!
