On the island of Knights and Knaves we have three people A, B and C. (The island must be known for its inhabitants’ very short names.) A says: We are all knaves. B says: Only one of us is a knave. Using an approach similar to the one in the notes, determine if A, B and C are each a knight or a knave. (The problem might have no solutions, one solution, or many solutions.)
