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: 2, 6, ['L', '1483', '9103', '7787', 'M', 'M', 'O', 'S', '8405', '6119', '4137', 'Y', '6191', 'A', '9955', '6385', '3097', '1463', '9947', '897', 'x', '371', 'B', '9975', '3939', 'B', '369']
