Design a finite state machine that handles an elevator system. The building has seven (7) floors. Consider that when moving between floors, the elevator must transition between floors from source floor to destination floor (i.e. a transition from floor 5 to 3 cant miraculously occur by skipping floor 4). The system can be locked with a key input such that the elevator cant be operated. Assume calls are made by pressing and holding push buttons. I need kamps and transition table
