    I used what known as 2’s compliment. Take the complement (flip all the bits - here that would give you 01110 which is 14) then add 1.

        My low level is a tad rusty from when I learned the C side in school, but if I recall the not operator resolves as a single Boolean (0 or 1 in true C), whereas compliment comes back as however many bits you put in - a not operation per bit.

        In C, the not operator is ! and the compliment operator is ~
