In this task, you are given inputs 'i', 'j', and A, where 'i' and 'j' are integers and A is a list. A list is shown by two brackets and comma-separated numbers and characters inside, like ['1', '12', 'l']. You need to concatenate all elements of A from the ith element to the jth element, and then reverse the resulting 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 reverse first and then concatenate.

Example Input: 22, 27, ['J', '5585', '3627', '1461', 'z', 'r', 'm', '8459', '5831', 'F', 'N', 'O', '1383', 'K', 'S', '3033', 'h', '5351', '2659', 's', 'B', '8067', 'k', '7393', '7027', 'x', 'U', '6565']
