odd question

[Jiri Barton]

Hello Karl,

I don't know the answer, but you can rewrite the expresion like this 

   return (i & k) | (j & k) | (i & j)

with the same meaning: all the combinations.

Supposing the variables are just plain booleans, f2 returns true if any two
of the three variables are true (or all three). It returns false if two
variables are false, or all the three are false.

My next suggestion is, maybe they are not integers. They might as well be
booleans.
