Definition: In this task, you are given inputs i,j, and A, where i and j are integers and A is a list. You need to return the sum of all the numerical elements in the list A between the positions i and j (including positions i and j). Return 0 if no numerical element is present in the list between the given ranges. i and j will be non-negative, and will always have a value less than the length of A. i will always be less than j.
Input: 13, 15, ['u', '1609', 'J', 'F', 'F', '6639', '2073', 'T', '5821', '3985', '3263', 'x', '485', 'j', '6275', '8311', 'z', '5439', 'P', '7393', '8277']
