Re: The Professors Test

Perhaps you should post your answer to part a, just in case you haven't got that quite right.

Re: The Professors Test

hi wintersolstice and anonimnystefy

Did you mean:

A says ‘None of us is lying’. B says ‘Only two of us are lying’. C says ‘Only one of us is lying’. D says all of us are lying.

The truth table below shows there is no solution to this.

The middle code must have 84 characters if it is to work.  A quick count suggests there are less.  But some spaces are double.  Your problem is to work out which.

Bob

I also must note that if we add the third person saying that they are all lying then the puzzle turns into a paradox.

I see what you mean

I figured out where the paradox is now

I think I need to re-do the liars puzzle completely.  Sorry about that.

Yes, that is correct!

hi,

that seems to be it, but check your wording.  You are contradicting yourself.
