Consider running binary search on input list: (2, 5, 8, 11, 15, 18, 23, 29, 31, 35) in searching for a target item x that is in the list, the running time of the algorithm may differ depending on which item from the list is the target. give a target item x, selected from the list, that results in the best running time. given a target item, selected from the list, that results in the worst running time.
