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, 23, ['6391', 'M', '8905', '3769', '9675', '4113', '9237', '8809', '8731', '1409', 'k', 'g', '6187', 'w', 'V', '2261', 'G', 'V', '2539', 'E', '2319', 'P', 'm', '8553', '6411']
Example Output: mP
