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: 2, 16, ['j', '8551', 'D', 'n', 'S', 'J', '1491', '8209', 'M', '4583', '8465', '8835', '1279', 'Q', 'C', 'z']
