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:
13, 20, ['z', '6473', '883', 'F', 't', '5379', '5471', '7621', 'q', '7731', '3525', '1077', '9929', '725', 'C', 'V', 'x', 'L', '3057', 'G', 'd', 'u', '4191', '6785', '1359', '5165']
