这道题运用的知识点是求最短路的算法.一种方法是利用BFS来求最短路. 需要注意的是,我们要用一个三维数组来表示此状态是否访问过,而不是三维数组.因为相同的坐标可以通过不同的穿墙方式到达. #include <bits/stdc++.h> using namespace std; struct Node{ int r; int c; int g; int cnt; Node(int r,int c,int g,int cnt):r(r),c(c),g(g),cnt(cnt){} }; ][][]…

A robot has to patrol around a rectangular area which is in a form of m x n grid (m rows and ncolumns). The rows are labeled from 1 to m. The columns are labeled from 1 to n. A cell (i, j)denotes the cell in row i and column j in the grid. At each st…
