A traffic signal cycles from GREEN to YELLOW, YELLOW to RED and RED to GREEN.
In each cycle, GREEN is turned on for 70 seconds, YELLOW is turned on for
5 seconds and the RED is turned on for 75 seconds. This traffic light has to be implemented
using a finite state machine (FSM). The only input to this FSM is a clock of 5 second period.
The minimum number of flip-flops required to implement this FSM is _______.
