Detailed Instructions: 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.
See one example below:
Problem: 3, 7, ['A', '23', '7413', '6933', '3369', '807', 'M', '456']
Solution: 18522
Explanation: Here, the numbers from 3rd to 7th position are '7413', '6933', '3369', and '807', hence their sum (7413+6933+3369+807) is 18522.

Problem: 7, 10, ['2721', '1023', '2363', 'J', 'J', '5867', 'x', 'w', '4247', 'i', '1193']
Solution:
4247
