AtCoder Heuristic Contest (AHC) is a series of programming contests held regularly on AtCoder. Unlike algorithm contests such as ABC/ARC/AGC, the goal is to create a better solution to a problem for which it is difficult to find the optimal solution. We will hold a long-term contest with a duration of more than a week and a short-term contest with a duration of less than a day, roughly alternately about once a month.

This is the last qualifying contest for AtCoder World Tour Finals 2025 to crown the world champion of AtCoder players. Please refer to this post for more details.

After the contest ends, all participants can post their approach on the Editorial tab. Please share your approach.

We are looking forward to your participation!
