Give the system architecture diagram showing all relevant system components and external systems $($if any$).$ What are the main modules? What are their interfaces? How are they connected to each other? according to the project attached in the picture SCENARIO:

Ticket Selling Machine

The activity is started by a Traveller actor who needs to buy a ticket. Ticket selling machine will

request trip information from Traveller. This information includes the number and type of tickets

$($one$-$way or round tickets$),$ route number, destination or zone number, etc.

Based on the provided trip info ticket selling machine will calculate the payment and request

payment options. Those options include payment by cash, or by credit or debit card. If payment

by card was selected by Traveller, another actor, Bank will participate in the activity by

authorizing the payment.

After payment is complete, the ticket is given to the Traveller. Cash payment might result in some

change, so the change is given back to the Traveller in this case. The ticket vending machine will

show a "Thank You" screen at the end of the activity.

Draw an Activity diagram for the given scenario.
