Hi guys I got given this stupid riddle and for the life of me I can't work it out.
If I get a cube and I hang it by a corner and cut it perfectly down the middle, what shape will the cross section be I get? It is a Isosceles Trapiziod?

>f(1)=/=f(0)
Nope.

f is, by your definition:
> f:{0,1,2,3}->{0,1,2,3}
So for each element x from the left stuff
>{0,1,2,3}
f associates a value y to the right stuff
>{0,1,2,3}
So f(1) can either be 0, 1, 2, 3 depending on f. 4 possibilities for 4 different f.
Same thing for f(2) and f(3).
You can have f1(1) = 0, f1(2) = 0,... or f2(1) = 1, f2(2) = 0, ... If you count them all, it's 4^3, and *2 if you add f(0)
