Description

IdeaShop, an online shopping company has created a special and unique truck system to deliver packages to customers efficiently. Each truck carries items based on their urgency, and the company uses a set of commands to manage all deliveries smoothly.

 

In order to make the system complete, the company needs you to implement the following commands:

1. add - When customers place an order, their items are added into the system. The packages are placed into the appropriate truck based on priority, making sure deliveries stay organized.

2. delete - If a customer changes their mind and cancels an order, the system will remove those items neatly from the trucks.

3. insert - Sometimes customers make special requests for faster delivery. In this case, their items are inserted directly into a specific position, helping them jump ahead in the queue.

4. move - If a customer is late in making payment, their package will be moved to a lower priority truck. If it reaches the lowest priority and still isn’t paid, the order will be removed from the system.

5. show - The manager can check the current arrangement of all packages at any time, viewing how items are distributed across the trucks.

6. promo - During special occasions, all packages (except those in the pending category) are consolidated into a single large truck, Bus B, for direct delivery. The items are then carefully rearranged using a strategic method to ensure better protection, especially for fragile packages.
