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, 23, ['Y', 'i', 'J', '9053', 'Q', 'G', 's', '403', 'j', 'G', 'z', 'E', '675', 'C', 'c', '2613', '475', '6599', '5099', 'x', '2599', 'b', 'H', '1423']
