Bagels

## Description

_Bagels_ is a mastermind game where the player must guess the computer’s code
and the computer will try to guess the player’s code at the same time. Codes
are four characters long and consist of the letters A through F in any order
and duplication. After each guess of the computer the player must answer how
many of the letters are exact (on the right position) and matches (in the
code, but on a different position). The computer does the same for the
player’s guesses. Whoever guesses the code first wins.
