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: 2, 8, ['I', '2513', 'u', 'a', '5715', '7101', '1519', 'x', '1803', 'F', '9917', '6925', '4795', 'A', 'd', 'h', 'w', 'Y', '1581']
