Question

A group of students creates a spin-off to commercialize the "Bravado" Safe using an innovative technology. They assign you to create the electronic mechanism to control the safe. These are the specifications:

Inputs: You have 10 numeric keys (0 to 9) plus a LOCK button.

Outputs: You have one output that commands the deadbolt (out=1 closes the safe, out=0 opens it).

When the safe is locked, you need to wait for the secret code (set to 1234 after much debating ) and then open the safe. If the safe is open, you need to enter the code backwards and then press the LOCK button to close the safe.

Draw the state flow diagram. Don't do anything else.
