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, 20, ['4881', '8409', 'S', '4771', 'j', 'a', 'g', 'j', '5633', '2483', 'J', 'W', '1399', 't', '2689', 'U', 'E', '8411', 't', '3535', 'h', '9827', 'T', '9409', 'C', 'e', 'd']
