Challenge: Device Boots Count

Завдання

Imagine that you work in a company that produces devices. You have been tasked with developing a function that will count the number of boots on this device: with each boot, the device must increase the number of boots by 1.

  1. Define the boots variable in the global scope.
  2. Make changeable the boots global variable inside the boot() function local scope.
  3. Increase the boots variable by 1 inside the boot() function.
  4. If the device is booting for the first time, display a message:
    "The device boot for the first time".
  5. If the device is booting 2+ times, display a message: "The device boot N times", where N is a boots variable.
