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.
This contest is one of the qualifying contests for AtCoder World Tour Finals 2026 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!
