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: 6, 16, ['q', '967', 'X', '8565', '3777', 'g', 'u', '5175', '2751', 'z', 'Y', 'H', '9631', '3379', '9381', '7197', '8101', 'p', 'E', 's', '2247', 'i', '209', '7833']
