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: 9, 13, ['9007', '2291', '1683', 'f', 'k', 'K', '6167', 'l', 'v', 'a', '2959', 'u', 's', '5411', 'f', 's', 'I', '2725', 'k', 'D']
Example Output: su9592av
