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: 15, 16, ['5393', '3349', '9933', 'e', 'H', '7969', '7543', '2239', 'a', 'H', 'I', '6889', 'O', 'q', 'm', '7145', 'j', '4411', '2813', '4425', '5879', 'a', 'G', 'l', '3101', '1427', 'r']
