input: Write a function to determine if it is possible to create an HTML page that displays a table of contents from the data stored in a database. The function should take a boolean value indicating whether the database connection is successful. If it is possible to create the HTML page, return "Yes", else return "No". If the input is not a boolean value, return "Invalid input".
  
  assert create_html_table(True) == "Yes"
  assert create_html_table(False) == "No"
  assert create_html_table("True") == "Invalid input"
  assert create_html_table(1) == "Invalid input"
  assert create_html_table(None) == "Invalid input"
output: def create_html_table(db_connection_success):
      if isinstance(db_connection_success, bool):
          return "Yes" if db_connection_success else "No"
      else:
          return "Invalid input"
