In this task, you are given inputs i, j, and A, where i and j are integers and A is a list. You need to find all elements of A from the ith element to the jth element, reverse the order in which they occur, and then concatenate them to output the resultant 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 concatenate the elements and then reverse the string.

Example Input: 4, 4, ['U', '5381', '9095', '9747', '7213', '3615', '1779', '1231', '4317', '2613', '7557', '9931', 'Q']
Example Output: 9747
