# Complete the closest_subtring function below. def closest_subtring(intList, n):

Nearest Sum Given a list of positive integers and an integer N, return the indices of the contiguous substring of the list whose constituents sum closest to N. If multiple pairs of indices meet these criteria return the one with the lowest starting index. If there are still ties, return the one with the lowest ending index. Please return the indices as a tuple in the form (lower index, higher index). In order to return a single element, just use that element's index twice Try to craft a solution with the lowest possible time complexity For example, if you're given the list: [3, 4, 5,6,7] and N 14, you should return (1,3)
