Chatbot will ask for feedback at the end of the chat session. The customer may teminate the interaction anytime. Task 1: (20%): State machine diagram 1. Development a state machine diagram for object "chat service" base on the above description. 2. Implement the state machine diagram (in class diagram) using state pattern.
