Re: question to ask potential coders

     A  B   math
     5  8   a=5  b=8
     5 13   b=b+a
     8 13   a=b-a
     8  5   b=b-a

     just a cute C trick, not really fair.  I like to spring it on the
     cocky canidates.  (the stack counts as a temp variable)

 Anyone else have a good question?

So how do you switch int vars without a temp?
I hope you don't say something silly like the stack or pointers...
