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, 12, ['w', 'a', 'c', 'y', 'x', '6045', '8207', 'D', 'E', '8003', '1769', 'w', '3445', '4157', 'e', 'h', '9913', 'E', '897', '6315', 'h', '545']
