FatMouse has stored some cheese in a city. The city can be considered as a square grid of dimension n: each grid location is labelled (p,q) where 0 <= p < n and 0 <= q < n. At each grid location Fatmouse has hid between 0 and 100 blocks of che…

直接爆搜肯定超时,除非你加了某种凡人不能想出来的剪枝...555 因为老鼠的路径上的点满足是递增的,所以满足一定的拓补关系,可以利用动态规划求解 但是复杂的拓补关系无法简单的用循环实现,所以直接采取记忆化搜索的方式进行DP,成功避免重叠子问题,避免超时 #include<iostream> #include<cstdio> #include<cstdlib> #include<cmath> #include<algorithm> #include…
