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: 20, 25, ['O', 'p', 'u', '9193', '229', 'y', '2537', '2811', 'B', 'o', '615', 'Y', 'O', '8093', 'i', '2243', '5469', '4029', '7123', 'D', 'B', 'I', 'X', 'P', '3865', '7571', '4411', '3499']
