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: 11, 15, ['4565', 'Q', 'C', '8503', 'n', 'B', 'r', '8589', 'h', 'v', 'B', '5755', 'h', '3595', '9739', 'X', 'n', '5393']
Example Output: 93795953h5575B
