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:
7, 25, ['8449', 'w', 'G', '6383', '1667', 'J', 'O', 'c', 'B', 'o', '523', '3043', 'S', '125', 'P', 'a', 'm', '1957', '4869', '1137', '6259', 'Q', '629', 'h', '3803']
