You aren't initializing row and col in main. So ideone and codeblocks probably set everything to false for you, but CodeForces doesn't.

I suggest making row and col global, since you need to use them in another function anyway. This should zero-initialize all values in the array.

Also, you may face RE or undefined behavior from index out of bounds in your northpole function.

while(s[i][p]!='#' and p<m)p++;
while(s[i][q]!='#' and q>=0)q--;

Your bounds check comes after using p or q as an index in the string.
