Digital combination safe Write a program to act as the digital combination lock for a safe. Create three buttons, representing the numbers 1, 2 and 3. The user clicks on the buttons, attempting to enter the correct numbers (say 331121). The program remains unhelpfully quiet until the correct buttons are pressed. Then it congratulates the user with a suitable message. A button is provided to restart.

Enhance the program so that it has another button which allows the user to change the safe’s combination, provided that the correct code has just been entered.
