@OnStarPrograms could you take a look?

I'm a bit confused, you seem to be submitting a fix for the 'solution' of such challenge but you're also changing the problem statement..

Is this intended ?

Yes, it is intended. In the original exercise the problem statement uses the numbers 16 and 14, but the solution proceeds as if the numbers were 256 and 14. Moreover, the solution is incorrect even when using 256 and 14. I decided to use 256 because I think it makes the exercise more interesting.
