Definition: 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.
Input: 21, 23, ['i', 'b', '2869', 'B', '5465', 'N', 'M', '9223', 'K', 'e', '3265', '6525', 'W', '3389', '3137', '503', 'x', '4333', '2073', 'v', 'e', 'a', '1881', '1281', 'D', '1981', 'L', 'T', 'h']
