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: 8, 18, ['A', 'f', 'R', 'Z', 'K', '4079', '2897', 'Q', 'n', 'L', '9861', '4631', '2955', 'n', 'e', 'M', '9225', '2993', '9055', '5967', '2421', 'x', 'B', '4969', '567']
