Part $2$: Consider the following problem description. Your task is to create a Use Case UML diagram

to illustrate the functional requirements of the described system.

Consider an online reservation system for a bus company. The company operates several buses,

each identified by a unique plate number and an assigned bus number. These buses follow a

predefined schedule, making stops at specified bus stations, with each bus undertaking only one

trip per day. Each trip includes a driver and a hostess, and for longer journeys, there are

scheduled breaks at service and rest areas. The trips are categorized into two types: normal trips,

which stop at intermediate stations, and express trips, which travel directly to the destination

without stopping.

Customers can reserve seats through the bus company's website, with the option to pay for the

seat online. If the seat is paid for, it cannot be cancelled by either the customer or the bus

company. If the seat is not paid for, the bus company reserves the right to cancel the reservation if

the customer does not show up at least one hour before the trip. Cancelled reservations free up

the seat, making it available for other customers. Both customers and company staff must

authenticate themselves to perform any operations within the system.
