input: Write a function to create a simple chatbot using Python and state diagrams. The function should initialize the conversation at state0, handle user input to transition between states according to predefined replies, and print out the conversation after ending the chat. If the current state has no replies, the conversation should end. The function should return the conversation as a list of messages.

How can I help you?', 'I need some advice', 'Sure, what kind of advice do you need?', 'Health advice', 'Focus on eating healthy and staying active. Make sure to consult a medical professional if you have any concerns.']
  assert chatbot_conversation(["Can you answer my questions?", "Why is coding so hard"]) == ['Hello! How can I help you?', 'Can you answer my questions?', 'Yes, I\'ll do my best! What do you want to know?', 'Why is coding so hard', 'Coding can be challenging, especially at first. Just remember that with practice, patience and problem solving skills you can overcome the obstacles.']
