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:
14, 15, ['G', 'e', '8891', '3441', '3257', 'c', 'O', 'T', '4859', '6639', '6913', 'R', 'O', 'H', '8083', '1621', '1501', '961', '5047', '1483', '1579']

Ex Output:
8083H
