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: 10, 18, ['n', 'v', 'p', '6541', 'D', '8551', 'A', '6483', 'O', 'm', '5499', '951', 'C', 'A', '9827', '2535', 'E', 'O']
