Revise algorithms by completing the following task and

Rail fares are based on the distance travelled:
• fewer than 5 miles:
£2.50
• 5–12 miles: £3.25
• more than 12 miles: £4.15
A processor in the
exit barrier calculates the fare. A discount of 10% is given for off-peak
travel, i.e. after 10 am and before 5 pm on Monday to Friday or any time on
Saturday and Sunday. The ID of the railway station at which a passenger starts
their journey is recorded on their card when they swipe in. The processor in
the exit barrier uses a data structure called ListOfStations to look up the
distance travelled.
Write an algorithm to
calculate the cost of a passenger’s journey. It must read in the start of the
journey from the card, calculate the fare and apply any discount. The
information must then be displayed in a customer-friendly way. (8)
