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: 8, 16, ['2243', 'j', '2909', 'u', '7445', 'H', 'U', 'W', 'Z', 'z', 'J', 'S', '1161', 'j', '6723', '2591', '9047', '4557', '9777', '2955', 'z', '4335', '9161']
