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){} }; ][][]…
非常适合A*的一道题. 比普通的迷宫问题加一个信息k表示当前穿过的障碍物的数量. #include<cstdio> #include<cstring> #include<queue> using namespace std; ; int m,n,k; int C[MAX][MAX][MAX]; int G[MAX][MAX]; int tarx,tary; struct node { int g,h; int x,y;//对于本题 x+y 越大距离终点越近 int k;…
