(b) Now suppose C can be any arbitrary array of n integers. Design and analyze a randomized algorithm with expected worst-case runtime of O(n 2 ) for the problem in this case. (10 points) Note: Actually, this problem also has a deterministic algorithm that runs in worst-case O(n 2 ) time. But you do not need to design such an algorithm for this problem (although if you do, you will receive the full credit for both parts (a) and (b)).
