5. Let F(n, m) denote the number of paths from top-left cell to bottom-right cell in a (n x m) grid (that only permits moving right or moving down). It satisfies the recurrence relation F(n, m) F(n-1, m) + F(n, m-1) What should be the initial condition for this recurrence relation? (Hint: What would be the number of paths if there was only a single row or a single column in the grid?)[5] Convince yourself that F(n, m) gives correct...
