So the line return sum(n)+sum(n-1) is incorrect; it needs to be n plus the sum of the n - 1 other values. This also makes sense as that's what you want to compute. You need to return a value for the base case and for the recursive case. As such you can simplify your code to: def sum(n): if n == 0: return 0 return n + sum(n - 1) WebApr 10, 2024 · Write a recursive function that returns the subsets of the array that sum to the target.
