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.

Example Input: 15, 22, ['m', '1863', 'y', 'w', '4919', '4857', 'S', 't', 'Z', 'n', 'X', '8677', '8587', '7313', 'G', 'U', 'P', 'G', 'E', '2083', 'L', 'k', '7637', '5725', '9821', 'S']
Example Output: kL2083EGPUG
