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: 11, 17, ['u', 'U', 'U', '7319', 'I', '7967', 'u', 'x', 'V', '713', 'C', '4237', '2385', 'F', '3867', 'E', '3809', 'x', 'l', '3679', 'K', 't', '5913', '57', '6951', '3019', '1491']
