For example, the sum of 52634 is 5+ 2 +6 +3 + 4 = 20. Write a recursive and iterative function sum (n) to compute the sum of all the digits in n. You may assume that n > 0. template.py 1 def sum R(n): if len(str(n)) == 1: 2- return n else: return 20 7. def sum_I(n): add = 0 8 while n: 10 add += n % 10 n //= 10 return add 11 12
