Modified traffic-light controller, 11-1. Modify the traffic light controller FSM of Table 14.4 so that it takes an additional input, carns, that indicates when there is a car waiting in the north-south direction. Change the logic so that, once the light changes to east-west, it stays with east-west green until a car is detected waiting in the north-south direction. Show a state table and state diagram for your new FSM.
