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: 4, 8, ['d', 'p', '3443', '9557', 'd', '8317', '2721', 'U', '2719', '249', 'c', 'O', 'v', '3961', '2569', '359']
Example Output: U12727138d7559
