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 find all elements of A from the ith element to the jth element, reverse the order in which they occur, and then concatenate them to output the resultant 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 concatenate the elements and then reverse the string.

Ex Input:
19, 24, ['j', 'n', 's', 'i', 't', '3013', '8761', '5025', '2653', '8887', 'l', 'V', '8193', 'N', 'F', 'A', '2925', 'h', 'F', '4259', 'a', 'w', '2939', '3473', '6489', '9199', 'r', 'O', 'O', 'l']

Ex Output:
34732939wa4259F
