Problem 1. (Sum of Integers) Implement the functions sumiter) and sum.rec() in sum of_ints.py that take an integer n as argument and return the sum S(n)1+2+3++n, computed iteratively (using a loop) and recursively. The recurrence equation for the latter implementation is If n = 1, n + S(n-1) if n > 1 S(n) = $ python3 sum of ints.py 100 5050 5050
