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: 5, 10, ['2271', 'T', '4811', 'L', '6875', 'q', '175', '5141', '2737', '1561', '5175', '595', '2857', 'U', '5785', '4113', 'a', '6047', 'g', 'z', '869', 'n']
