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, 16, ['i', 'x', '307', '9951', '555', 'R', 'q', 'C', '5053', 'n', '5029', 'y', '1829', '8749', 'J', '1733', 'a', '8079', 'Y']
