input: Write a function to create an AI-based chatbot in Python that can answer simple queries about a product or service. It should provide predefined responses for certain questions and generate random responses for unknown queries. The chatbot should continue to prompt the user for more queries until the user says goodbye.
  assert generate_response('What is XYZ?')=='XYZ is a company that provides XYZ services.'
  assert generate_response('Where is XYZ located?')=='XYZ is located in ABC city.'
  assert generate_response('What do apples taste like?')=='I am not sure I understand.'
  assert generate_response('What are the benefits of using XYZ?')=='XYZ provides a quick and easy way to find solutions to your problems.'
  assert generate_response('Can you help me with something else?')=='Can I help you with something else?'
output: def generate_response(query):
      responses = {
          'What is XYZ?': 'XYZ is a company that provides XYZ services.',
          'Where is XYZ located?': 'XYZ is located in ABC city.',
          'What are the benefits of using XYZ?': 'XYZ provides a quick and easy way to find solutions to your problems.',
          'Can you help me with something else?': 'Can I help you with something else?'
      }
      return responses.get(query, 'I am not sure I understand.')
