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: 18, 18, ['M', '2359', 'M', '3705', 'j', '7553', '3287', '505', 'U', '7065', '2755', 'g', '6799', 'B', 'j', 'D', 'P', 'a', 'u']
