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: 18, 19, ['5115', 'b', 'B', '9739', '4509', 'D', 'P', 'p', '9235', '9517', '7279', '8703', '8535', '5943', '1527', 'N', 'U', '3099', 'c', '5173', 'V', '3539', '8043', 'l']
Solution:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
