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: 3, 6, ['v', 'a', '6769', 'y', '3703', '9867', 'A', '6017', 'D', '8543', 'm', '5831', 'c', 'L', 'b', '8293', '8629', 'X', '3371']
