The recent schoolwork is heavy, which was inscribed for two days. Last night when I went to bed, I suddenly thought of the final solution.I don't know if it should be called topology. It feels quite like it. The title is called the class topology. The method of the problem is to use a map to mark the existence of the state, and then using a similar topology method to constantly find the remaining stable after the block, I used two priority queue to ma
