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: 16, 19, ['g', 'c', '157', '7487', 'Q', 'x', '7719', '3859', 'O', '4597', 'Q', 'o', '103', 'n', '1513', 'n', '1667', '6417', 'i', '2685', '1259', '6483', '4381', 'g', 'c', '3849', 'Q', '6591']
Example Output: i71467661n
