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: 15, 16, ['1653', '7507', 'X', '6095', 'J', 'F', 'x', 'O', 'r', '1425', 'H', 'v', '5947', 'N', '5891', 'b', 'H']
Example Output: b1985
