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, 15, ['S', '665', 'C', '3233', '7333', 'Z', '29', '9299', 'F', '245', '2181', '8973', '2007', '5229', 'u', '8833', 'C', 'x', '963', '7439']
