Given the task definition, example input & output, solve the new input case.
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.
Example: 3, 7, ['A', '23', '7413', '6933', '3369', '807', 'M', '456']
Output: 18522
Here, the numbers from 3rd to 7th position are '7413', '6933', '3369', and '807', hence their sum (7413+6933+3369+807) is 18522.

New input case for you: 10, 20, ['4857', 'v', '3419', 'F', 'd', '2951', '7703', '3525', '3811', 'n', 'l', '6155', '597', 'O', '9215', '7949', 'K', '4945', '8571', 'C', 'r', 'p', '701', '6955', '5329', '4277', '6975', '8375', 'L']
Output:

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.
