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: 3, 18, ['L', 'I', '6065', '8723', '7903', 'O', 'v', '6113', '5323', 'Z', '5863', '5353', '9055', 'c', 'v', '3749', 'L', '6023', '3191', 'N', 'D', '461', 't', 'G', '5781', 'u']
