PHP generates maze and maze addressing algorithm examples to solve the idea

PHP generates maze and maze addressing algorithm examples has finally improved compared to the previous. The algorithm for generating the maze and the addressing algorithm are actually the same. Just one with the traversal one used recursion. Refer to the online Mike Gold algorithm.

Description为了便于牛们欣赏和锻炼,农夫JOHN在他的农场上新添加了一个美丽的池塘。 JOHN的池塘是一个长方形,他已经把它划分成了M行N列的小正方行 (1 Input第1行: 两个整数, M 和 N。第2~M+1行: 第i+1包含N个数,分别为第i行的N个格子的情况。 0表示格子为空,1表示有一片荷叶,2表示格子里有石头,3表示此格子是Bessie的起点,4 表示此格子是Bessie的目标。Output第1行: 一个数,最少情况下需要添加的荷叶数目。如果没有方案存在,输出- 1。第2行: 一个数,达到最小值的方案总数。这个数保证不超过内设64位整数(long long/ int64)的大小。如果第一行是-1,不要输出此行。Sample Input4 51 0 0 0 03 0 0 0 00 0 2 0 00 0 0 4 0输入解释:池塘含4行5列。Bessie在第2行第1列并且想跳到第4行第4列。池塘里有1块石头和3片荷叶。Sample Output23输出解释:至少需要2片荷叶。一共有三种摆法:第4行第2列,第2行第3列第1行第3列,第3行第2列第1行第3列,第2行第5列
