Yandex Cup 23 Algorithm Final

We plan to use the tasks for the codeforces round in the future, so please do not discuss the tasks publicly.

You will have 240 minutes to solve the problems.

The ranking of participants will be based on the score of solved tasks, and in case of a tie, the one with the fewer penalties will be higher. Penalty is the time from the beginning of the contest when the number of points last increased. More details can be found in the championship rules.

Good luck!
