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:
2, 5, ['5587', 'e', '821', '8017', 'i', 'u', '7627', 'r', '477', 'a', 'y', '8417', '5485', '4659', '91', '6073', 'b', 'G', 'l', '5085', '1745']

Ex Output:
i8017821e
