For the following complexity classes provide a description, example and solution. In the de- scription make sure you identify a problem, solution, mathematical description and pseudocode. The example should follow the description and contain a figure, table or diagram as appropriate to better explain your problem. In the solution a series of steps or verification should be provided. (a) Polynomial-time (P).(b) Nondeterministic Polynomial-time (NP). (c) NP-Complete.(d) NP-Hard.(e) P=NP.
