Question:
Design a data structure for an ice cream shop to show people in line at any given time. Your data structure should satisfy the following interfaces:
class IceCreamShop:
add_person_to_line(name): return None
serve_ice_cream(): return name (or None if no one in line)
get_people_in_line(): return list of names
Your data structure will be called as such:
shop = IceCreamShop()
shop.add_person_to_line('John')
shop.add_person_to_line('Jill')
shop.serve_ice_cream()
shop.add_person_to_line('Kim')
shop.get_people_in_line()
