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, 19, ['W', '8995', '6027', 'b', 'd', '8751', '1875', 'M', '9411', 'E', '5763', '9131', '7731', 'l', '6623', '6787', '3835', 'l', '1571', '4053', '3773', '6303', '8557', '5899', '3803']
