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, 9, ['1735', '9629', 'O', '8485', '1643', '4091', '2979', '1663', 'S', 'u', '731', 'y', '9841', 'e']

Ex Output:
