Part $1$: Consider the following code$/$pseudocode$.$ Draw a

sequence diagram that represents this code, you should include

all$/$any non$-$boundary objects $($i$.$e$.,$ classes$)$ involved in the

code. Note: screenshots from other websites$/$tools will not be

accepted $(0$ mark$)$

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.
