Real-time Ticket Purchasing System

optiver Description Design a real-time concert ticket purchasing system. The service publishes available ticket information in multiple packets. You have a wishlist of artists you want to see, the maximum price you're willing to pay, and the minimum number of seats you want to purchase. Design a program to listen for available tickets and make purchases according to criteria. Requirements Received 'AvailableTicket' message format: Packet 1: Message ID and Artist ID Packet 2: Message ID and Ticket Price Packet 3: Message ID and Available Seats Message IDs are unique for a set of packets and are not reused. Order of packets for the same message ID is guaranteed, but packets from different messages can be interleaved. Order response format: Packet 1: Artist ID Packet 2: Number of seats to purchase Write the following interface: ConcertTickets.__init__(): Initialization method. ConcertTickets.on_receive_requirements: Takes parameters: artist ID, maximum price, minimum seats. ConcertTickets.process_packet(int message_id, str data) -> int: Processes the packet, returns order response packet based on criteria. Return 0 if no order. Example Input concert = ConcertTickets() concert.on_receive_requirements(artist_id=1, max_price=100, min_seats=2) concert.process_packet(message_id=1, data="artist_id:1") concert.process_packet(message_id=1, data="price:90") concert.process_packet(message_id=1, data="seats:3") Constraints Number of artists and tickets is limited. Packet order is guaranteed by message ID. Example Input concert.on_receive_requirements(artist_id=1, max_price=100, min_seats=2) concert.process_packet(message_id=1, data="artist_id:1") concert.process_packet(message_id=1, data="price:80") concert.process_packet(message_id=1, data="seats:3")
