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: 1, 8, ['j', 'N', 'U', '1599', '3287', '7799', '6225', 'd', 'G', 'K', 'Q', 'o', '8471', 'I', '4243', 'a', '7417', '2185', 'N', 'Y', '6471', 'e', 'K', 'y', '8641', 'i']
