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: 18, 22, ['Y', 'S', 'Z', 'P', '247', '6733', 'Q', '3987', '2907', 'E', 'F', '6065', 'T', '9231', '1589', 'i', '9191', 'h', 'D', 'j', '7139', '7769', 'v', 'r', '8711', 'N']
