Teacher: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.
Teacher: Now, understand the problem? Solve this instance: 7, 7, ['8481', '3337', 'd', 'v', 'x', 'U', '9387', '1969', '1705', '8625', 'R', 'S', '4797', 'r', '5757', '8739', '8945', 'p', '8263', '5263', '9651', 'H', 'M', '2789', '3665', 'r', '8993', '343', 's', 'o']
