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: 5, 5, ['8095', 'D', '9477', '9307', '9355', 'U', 'y', '5197', '2691', '3061']
Example Output: 5539

Example Input: 5, 9, ['g', 'B', '7695', 'X', 'h', 'A', '693', 'x', 'Q', 'l', 'Q', '9223', 'y', 'a', 'q']
Example Output: Qx396Ah
