Write all first digits in guesses with 1 or more points: '8'
First digit is 8.
Write all second digits in guesses with 1 or more points: '1','4'
Because 815 have 1 correct digits and that digit is 8, second digit is not 1,
so second digit is 4.
816 and 848 both have a score of 2, and because second digit in 816 is
not the correct one, that means the third one is.
so the correct number is 846
