Codebreaker

Codebreaker is a logic game in which a code-breaker tries to break a secret code created by a code-maker. The codemaker, which will be played by the application we’re going to write, creates a secret code of four numbers between 1 and 6. The codebreaker gets some number of chances to break the code (depends on chosen difficulty). In each turn, the codebreaker makes a guess of 4 numbers. The codemaker then marks the guess with up to 4 signs - + or - or empty spaces.

• A + indicates an exact match: one of the numbers in the guess is the same as one of the numbers in the secret code and in the same position.
• A - indicates a number match: one of the numbers in the guess is the same as one of the numbers in the secret code but in a different position.
• An empty space indicates that there is not a current digit in a secret number.
