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: 12, 12, ['c', 'a', 'G', 't', '753', 'x', 'I', '4479', 'i', 'y', 'J', 'w']
Example Output: w

Example Input: 8, 8, ['n', '9001', 't', 'e', 'W', '2287', 'f', '2735', 'z', '3065', 'J', '5609', 'e', 's', 'F']
Example Output: 5372

Example Input: 3, 16, ['7879', 'O', 'W', 'u', '4587', 'x', 'n', '275', 'B', '183', '8603', 'd', '6881', 'T', '3673', 'N', '8839', 'h', '285', 'j', '5705', 'c', 'W', '6773', '5557']
Example Output:
