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 4 inhabitants: Charlotte, Noah, Aiden, and Logan. Charlotte told you that Aiden is a knight or Noah is a knave. In Noah's words: "Logan is a knight if and only if Aiden is a knight". Aiden commented, "Charlotte is a knave". Logan told you that If Logan is a knight then Noah 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.

Assume Charlotte is a knight.  No contradiction is found in their claim that Aiden is a knight or Noah is a knave.
 Aiden cannot be a knight, because this would contradict the claim of their own that Charlotte is a knave.
 Assume Aiden is a knave.  No contradiction is found in their false claim that Charlotte is a knave.
 Noah cannot be a knight, because this would contradict the claim of Charlotte that Aiden is a knight or Noah is a knave.
 Assume Noah is a knave.  No contradiction is found in their false claim that Logan is a knight if and only if Aiden is a knight.
