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: 5, 8, ['977', '9427', 'b', 'y', 'Q', 'z', '8989', '6961', '5259', '499', 'W', 'F', '8641', 'f', 'L', '1541', '3351', 'd']
Example Output: 69618989zQ
