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:
17, 21, ['G', '6731', '5011', '5327', 'K', '1601', '7927', 'H', 'Q', '2519', '7897', 'G', 'x', '4253', 'g', 'o', 'D', 'A', '6515', 'o', '9255', 'V', '6725', 'l', '5771', '783']

Ex Output:
9255o6515AD
