Implement the Master Mind) board game.

The computer "thinks" a number with 4 different digits.
The user guesses which digits.
For every digit that matched both in value, and in location the computer gives a *.
For every digit that matches in value, but not in space the computer gives you a +.
The user tries to guess the given number in as few guesses as possible.


Computer:
2153       (this is hidden)

User    Response
2467    *        (because 2 is in the right place but none of the other digits match)
2715    *++      (because 2 is in the right place. 1 and 5 are used but in the wrong place. 7 not in use)

Wordle is basically the same game, just with letters and the extra limitation that each guess must be a valid word.
