PROBLEM $7.$ Create a function to request a taxi having the following interface:

requestTaxi $->$ PassengerTelephoneNumber, PassengerLocation, PassengerDestination $->$ void

If the start and end locations are the same then an appropriate error message is to be displayed and no further action is to be taken. The appropriate error message is "Start and end locations are the same!"

Provided that the locations are correct, the fare should be displayed and the passenger asked to enter $$Y$$ to confirm the trip or $$N$$ to cancel. The specific message to the passenger is 'Enter $"$Y$"$ to confirm the trip or $"$N$"$ to cancel $-\text{'}.$

After the user confirms the trip, you should determine if there is a driver available. If so$,$ execute the trip. The driver should now be reflected in the destination location and their trip count should have increased. Reset any failed trip attempts the passenger had to zero. If not, record the failed attempt for this passenger by adding $1$ and display an appropriate error message. The appropriate error message is $\text{'}$No driver available'.

For Problem $7,$ in the function $,$ the parameters PassengerLocation and PassengerDestination will contain only one of the following, "UWI", "Papine", "Liguanea", "Half$-$Way$-$Tree". Where the start and end locations are the same, the appropriate error message is "Start and end locations are the same!" Only the calculated fare should be displayed $($i$.$e$.$ without any message or description$).$ After the fare is displayed, the message to the passenger is 'Enter $"$Y$"$ to confirm the trip or $"$N$"$ to cancel $-\text{'}.$ For a failed attempt, the appropriate error message is $\text{'}$No driver available'.
