Create a program that models a simple subway system.

• The program takes the line and stop that a user is getting on at and the line and stop that user is getting off at and prints the total number of stopsfor the trip.

There are 3 subway lines:

The Red line has the following stops:

  red_line = south station, park st, kendall, central, harvard, porter, davis, alewife

The Green line has the following stops:

  green_line = haymarket, government center, park st, bolyston, arlington, copley

The Orange line has the following stops:

  orange_line = north station, haymarket, park st, state, downtown crossing, chinatown, back bay, forest hills

All 3 subway lines intersect at park st, but there are no other intersection points. Some of this MBTA is fictionalized. Haymarket does not connect the orange/green lines.

• Assume good user input. Don't do lots of checking to ensure good input.

• You should be able to try to calculate the distance in your code without user input, but in the end we'll want user input.

• You need to prompt the user for four pieces of input data.

• Consider diagraming the lines by sketching out the subway lines and their stops and intersection.

• The key to the lab is to find the intersection of the lines at park st.
