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, 27, ['o', 'A', '3419', '9941', '5639', 'l', '2031', '8151', '6519', '8763', '1403', 'I', 'F', '8807', '4017', 'f', 'S', '3625', '3719', 'H', 'Q', '5125', 'C', 'h', '6165', 'B', '1807', '4425']
