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, 15, ['i', '4905', '277', 'c', 'D', '8949', '9921', '9893', 'C', 'n', '4001', '45', 'J', '3731', '1275', '3403', '5141', 'o', 'j', 'M']
