The following method, numPaths, is supposed to count the number of paths, but it has some problems. Debug the method. Show what the issue is and how to fix it.

int numPaths(int row, int col, int n) { if (row == n) return 1; else if (col == n) return (numPaths + 1); else return (numPaths(row + 1, col) * numPaths(row, col + 1)) }
