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: 2, 16, ['A', '6877', '6873', '9875', '721', '9993', '9959', 'f', '4715', 'd', '11', '267', 'q', 'r', '2167', 'H', '7073', '4421', '1519', 'a', '1787', 'p', 'A', 'W', 'l', '5881', '239', 'b', 'g']
