and .You have **150 minutes** (previously updated from 120) to solve 4 problems with difficulty ranging from CCC J3 to S3. Each problem is worth a total of \(100\) points.

**Additional Information:**

- Make sure you read all of the problems. There will be subtasks that allow you to get partial points, and every point counts.
- All problems have been tested with C++ and Python. The time limit for each problem will be at least 2x the reference solution's execution time.
- As with any contest,
**discussing contest problems before the contest end date is strictly prohibited.**The only exception is the post-contest discussion channel in the club server, which can only be accessed once your window is over.

Good luck!
