Teacher:In this task, you are given inputs 'i', 'j', and A, where 'i' and 'j' are integers and A is a list. A list is shown by two brackets and comma-separated numbers and characters inside, like ['1', '12', 'l']. You need to concatenate all elements of A from the ith element to the jth element, and then reverse the resulting string. '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'. Perform the operations in order, i.e., do not reverse first and then concatenate.
Teacher: Now, understand the problem? Solve this instance: 8, 23, ['m', '7579', 'I', 'b', 'X', 'I', 'F', 'w', 'j', '673', 'X', '4733', 'S', '6381', 'x', 'f', '169', '3823', '5239', '5367', 'F', '911', 'c', '5279']
Student:

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.
