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, 16, ['901', '2615', 'z', '6183', '9447', '7021', '1199', '6021', 'E', 'E', '6105', '2089', '8831', 'v', '1265', 'a', '717', 't', '3307', 'F', 'D']
