We would like to express our great gratitude to:

You will have 2 hours to solve 5 problems, one of which is divided into two subtasks.

The scoring distribution is 500 — 1000 — 1500 — 1750 — (2000 — 2000)

We have tried to make clear statements and strong pretests for the problems and hope you will have fun and increase your rating!
