定义一个二维数组N*M(其中2<=N<=10;2<=M<=10),如5 × 5数组下所示:
int maze[5][5] = {
0, 1, 0, 0, 0,
0, 1, 0, 1, 0,
0, 0, 0, 0, 0,
0, 1, 1, 1, 0,
0, 0, 0, 1, 0,
};
它表示一个迷宫,其中的1表示墙壁,0表示可以走的路,只能横着走或竖着走,不能斜着走,要求编程序找出从左上角到右下角的最短路线。入口点为[0,0],既第一空格是可以走的路。
Input
一个N × M的二维数组,表示一个迷宫。数据保证有唯一解,不考虑有多解的情况,即迷宫只有一条通道。
Output
左上角到右下角的最短路径,格式如样例所示。
5 5
0 1 0 0 0
0 1 0 1 0
0 0 0 0 0
0 1 1 1 0
0 0 0 1 0
输出
(0,0)
(1,0)
(2,0)
(2,1)
(2,2)
(2,3)
(2,4)
(3,4)
(4,4)
