AC代码：

#include 
using namespace std;
string str[505];
int n,m,pos;
bool flag;
 
void dfs(int x,int y,int h){
  while(1){
    if(x == -1 || y == -1 || x == n || y == m){
      if(x == n) flag = true, pos = y + 1;
      break;
    }
    // cout<= 0 && y >= 0 && x < n && y < m && str[x][y] != '.'){
      // cout<= 0 && y >= 0 && x < n && y < m && str[x][y] == '.'){
      if(h == 0)x = x + 1;
      if(h == 1)x = x - 1;
      if(h == 2)y = y - 1;
      if(h == 3)y = y + 1;
    }
  }
}
 
int main()
{
  scanf("%d%d",&n,&m);
  for(int i=0;i>str[i];
  }
  for(int i=0;i
