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: 2, 24, ['D', 'I', '6457', 'a', '7827', '605', '637', 'l', '7505', 'B', 'C', 's', 't', 'r', '7433', '7831', '707', '5721', 'q', 'V', '5315', 't', 'R', '6985', 'v', '8837', '8729', '3383']
