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: 13, 17, ['O', '9203', 'l', '6287', 'E', '2551', '4447', '1485', 'n', 'n', 'U', 'U', 't', '9843', 'D', 'L', '5627', '6197', 'E', 'a', 'a', 'T']
