Question

Write a recursive method in java  public static long numPaths(int r, int c)

which can solve the following scenario: a checker is placed on a checkerboard.
         What are the fewest moves to get to the upper left corner(0,0)?  You can only move sideways or
         vertically.  No diagonal moves.
         Once you have that calculation, how many different ways are there to get to the
         upper left corner?

this is my code but I am getting stock overflow, I'm not reaching my base case.
     

 public static long numPaths(int r, int c)
    {
        //base case
        if (r==0 && c==0 || r==0 || c==0)
            return 1;
        else {
            return numPaths(r, c--) + numPaths(r--, c);
        }
    }
