Question Three 2 Marks What will be the efficiency class of the exhaustive search algorithm outlined in the text for the traveling salesman problem, assuming that each tour can be generated in constant time? Explain your answer. Question Four 3 Marks Write a Brute force algorithm to find all the common elements in two lists of integer numbers. (e.g., the output for the lists [1, 3, 4, 7] and [1, 2, 3, 4, 5, 6] should be 1, 3, 4). Show the time complexity of the algorithm if the lengths of the two given lists are m and n, respectively.
