I think Jamal should put the purple car so
where point A(s) faces in N and then B
faces the back. Or, he can move the green
car to where it should be part D(n) faces S
and part C faces the back. I think this

+ N facing each other, it won't move the

apart. Also, the same thing for the green
car, if you keep the green car with S + S
facing each other, it won't move the car at
all and it would force each other apart.
