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.
One example: 3, 7, ['A', '23', '7413', '6933', '3369', '807', 'M', '456']
Solution is here: 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.

Now, solve this: 4, 10, ['r', 'f', '7149', '2641', '4411', 'r', '4951', 'F', 'o', 'A', 'r', 'x', '9685', '1065', 'G']
Solution:
