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: 8, 9, ['E', '4081', '2021', '2585', 'I', '6983', '3271', 'K', '4793', 'd', '2835', 'Q', 'T', 'f', '2133', 's', 'G', '93', 'B', 'n', 'b', 'v', 'N', 'B', '6625', 'v', 'd', '5407']
Example Output: 3974K
