I agree. I wrote something to the effect of:
If you don't care about the other truth table combinations then its simple:
<puts not gate just before X>
If you do care, then I couldn't just do it with one extra logic gate:
<Does boolean algebra and pumps out wierd (but functioning) circuit>...
Well unless you get under the table, you're not going to be able to half the combos.
The point they're trying to make is if i have
............2
....7..............5
8......................1
....3...............4
............6
and you flip it over... its the...
Because the necklace can be viewed from either side:
What appears to be two different combos, is just one, because when you flip it they're the same.
Hard to explain without showing you.
But its just the circle thing: 11! divided by 2 because there are half as many possible combos.
Yeah my hand was way more sore than it was for paper one. Hmm. it was a good paper. Not sure if I owned it as much as paper one becuase near the end i was just writing crappity crap, but it was still pretty good.
Just by thinking along those lines you're about 90% of the way to a root.
ALthough its not just an attempt to bang her, as Legham said, make sure she doesn't see it that way.
