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: 16, 25, ['N', 's', '5961', 'V', 'L', '8287', '255', '9273', '5171', 'p', '4903', 'U', 'z', 'A', 'N', '4495', '1861', 'a', 'k', 'c', '1777', '8053', '8811', 'k', '4643', 'U', '7203']
