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, 17, ['4713', '8187', '7303', 'u', '8625', 'g', 'D', 'x', '3451', '8939', '7739', '8607', 'L', '7573', 'o', 'B', '2619', '4981', '3789', 'o', '8491']

Ex Output:
2619Bo7573
