2. Say you have a problem. You know of an algorithm which can solve it in e(2") time, and you know a method that takes O(n) time to check and see if a proposed answer is valid for any given problem instance. Is this enough to know whether or not the problem is in each of the three complexity classes below? Explain each answer. 2a) P 2b) NP 2c) NP-complete
