::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

As this project show you a simple game, I implement a Computer AI that will allow him to randomize a number from 1-3. Therefore, it is up for the user to choose.

Once the User chooses, it then tries to measure the conditions programmed and display the result.
