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: Samuel, Victoria, Liam, Charlotte, and Isabella. "Samuel is a knight and Isabella is a knave," Samuel declared. Victoria noted, "Samuel is a knave". "Charlotte is a knight" - Liam. Charlotte said that If Victoria is a knight then Samuel is a knave. Isabella commented, "Liam is a knight if and only if Victoria 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.
