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: 12, 17, ['T', 'o', 'e', '5003', 'r', '1309', '6761', 'h', '7471', '7863', '8521', 'L', '8941', '4289', '5099', '9433', 'U', '387', '5857', '9301', '5107', 'J', '1949', '7591', '4167', '1385', '4517', 'A']
Example Output: U9433509942898941L
