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, ['4733', 'G', '9275', '7757', 'I', 'v', 'z', 'p', 'Z']
Example Output: I

Example Input: 2, 4, ['5983', 'I', '9531', 'U', 'P', '1383', 'Y']
Example Output: U1359I
