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: 16, 20, ['j', 'Z', 'g', 'v', '3745', '7929', 'Z', 'x', 'n', '8865', '6177', '9821', '5947', 'T', 'm', 'D', '2163', '2695', '6723', 'C', '1665', '2063', 'k', 'a', 'M', '5671']
