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: 10, 15, ['D', '8659', '9521', '2149', 'Y', '6083', '3123', 'k', 'D', '2295', '8227', 'y', 'a', 'Y', '2711', 'I', '4907', 'D', '7773', 'U', '523', 'a', '865']
