Contest Rules

This contest is full-feedback (solutions are judged during the contest).
When you solve a problem, you get 100 points for each problem. Competitors are ranked first by total scores, then by penalties. The penalties are computed as (sum of times of AC for all solved problems) + (20 minutes) * (the number of incorrect attempts for solved problems).
The scoreboard will be frozen 60 minutes before the end of the contest.
All problems in this contest are solvable in C++23 (GCC 15.2.0) and Python (PyPy 3.11-v7.3.20). We do not guarantee that all problems are solvable in other programming languages.
The problems are ordered as follows:
The problems are sorted by difficulty.
Problem statements are provided in Korean, English, and Japanese.
