Design a speed warning system that receives on two lines, an indication of the
speed limit on the highway. There are three possible values 45, 55, or 65 MPH.
It receives from the automobile, on two other lines, an indication of the speed of
the vehicle. There are four possible values under 45, between 46 and 55,
between 56 and 65, and over 65 MPH. It produces two outputs. The first, F,
indicates whether the car is going above the speed limit. The second, G, indicates
that the car is driving at a "dangerous speed" _ defined as either over 65 MPH or
more than 10 MPH above the speed limit. The inputs are coded as follows:
