So how fast are your solutions? How many itoa's can you perform in a 
second? My implementation does about 3.3 million per second on a 3.0GHz 
machine running RHEL3.

I guess I could test the code myself, but I'm not at work any more 
today, and won't be back until Monday, or until I next connect to the 
VPN. :)


P.S. This was fun. I think the last time we had a good code optimization 
conversation was when Sasha posted a challenge. Thanks Sasha! Let's do 
that again some time.

P.P.S. Levi, I love the static array code where you index into a string 
literal. Awesome stuff. Those K&R fellows sure were smart about their C 
code. Almost as if they "wrote the book" on C... ;)
