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:
9, 15, ['9275', 'R', 'c', '897', 'm', '2477', '7233', '3477', 'd', 'D', '2765', 'f', '5149', 'S', 'R', 'r', '1531', 'M', '7997', '2057', '1261', '8321', 'H', '2943', '8893', 'v', 'X']
