Consider a recursive function sumDigit sR (num) that returns the sum

Consider a recursive function sumDigit sR (num) that returns the sum of the digits of the input parameter, which is an integer called num. It can be assumed that 'num' is a non-negative For example: sumDigitsR (1983)=21. If sumDigitsR was re-written into an iterative version, what would be the space complexity of the iterative algorithm? O(n2) O(n) O(1) O(logn) None of the other answers are correct
