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: 3, 13, ['2889', '2395', '4059', '2829', '4333', '5199', '3747', 'm', 'r', 'u', 'Z', '9509', '5979', 'o', 'Q', 'Q', '1497', '1673', 'l', '3899', 'D']
