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: 15, 28, ['G', 'F', '1819', '4909', '5973', 'g', '3461', 'A', 'U', 'E', 'c', '5331', '7885', 'W', 'a', '3017', 'C', '6061', 'z', 'U', '9809', '3061', 'F', 'D', 'r', '7447', '5071', '5909', 't', '9513']
