I have good evidence that you guys -- the readers that I slave for -- are very smart.
But we still have no winner on last week's Friday Free Stuff. What's that all about?
Have I "Stumped the Chump?" (good writers borrow; great writers steal.)
This is the last call...
What does the following function compute?
// Assumes val is odd
static int mysteryFunction(int val) {
int t = val;
t *= 2 - val*t;
t *= 2 - val*t;
t *= 2 - val*t;
t *= 2 - val*t;
return t;
}
I got the question from "Click and Hack, the type-it brothers" .....
...aka Dr. Joshua Bloch and Dr. Neal Gafter. (Did you know they have two JavaOne sessions: One, Two.)
The prize (Duke dolls) ...

Friday Free Stuff is not a contest. Mary is giving away something she personally owns to somebody she picks. She pays for shipping. Sun employees can play but can't "win."
