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: 13, 16, ['z', '5051', '4499', 'W', 'X', '8861', 's', 'd', 'd', '4987', 'X', '6171', '7587', 'c', 'h', '9101', 'r', '6753', 'M', '3501', 'b', 'b']
Example Output: 9101hc7587
