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: 7, 11, ['2481', 'b', 'O', '617', 'B', '9201', 'R', '1063', '3715', 'g', '8881', '3613', 'F']
Example Output: 8881g37151063R
