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: 19, 22, ['y', 'B', '6127', '8911', '9267', '755', '6921', 'U', '3263', '983', 'W', '5715', 'i', '6425', '5223', '6801', 'K', '5493', '5703', '3939', '797', '7003', '4915', 'S', '2651', '1371']
