Create a java-program RaceTrack that implements the game in Java and uses StdDraw to show the result. The game should use a track like the one beneath and it should be possible to change the size of the track.

The user controls the car by using the numerical keys 1-9. Everytime the user has entered a number followed by 'enter' the line in the window should move to show the progress.

The figure shows an example of what the window can look like, after the user has entered the sequence 6, 2, 6, 9.
