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: 14, 21, ['595', '2203', 'F', 'M', '7861', '2363', 'M', 'q', 'k', 'c', 'f', 'v', '4515', '6295', 'T', '9073', 'A', '1659', '9983', 'O', '5127', 'B', 'j', '859', 'l', '3809', 'o']
