A conversation between User and Assistant. The user asks a question, and the Assistant solves it. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer.
User: A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 5 inhabitants: Charlotte, Noah, Lucas, Sofia, and Aiden. Charlotte commented, "Aiden is a knight and Lucas is a knight". Noah told you that Charlotte is a knight if and only if Aiden is a knave. "Lucas is a knight if and only if Noah is a knight," Lucas claimed. Sofia told you that Noah is not a knave. Aiden said that If Sofia is a knight then Charlotte is a knave. So who is a knight and who is a knave? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags, for example <answer> (1) Zoey is a knight
(2) Oliver is a knight
(3)... </answer>.
Assistant: Let me solve this step by step.
