About that "Cheryl's Birthday" problem that's been floating around...

[usernamenumber]

I'm curious how many people got it, and how easily. Not to sound cocky but the answer was pretty obvious to me, and I'm wondering if it's the kind of thing that benefits from "thinking like a programmer" (and no, I can't quite articulate what I mean by that in this context), or if it's something more general.

I found it trivial and it makes me sad that so many of my friends not only couldn't solve it, but basically ran screaming from it as though it was some type of pernicious monster. Or stared blankly at it like a deer in the headlights.

It's a simple binary logic problem. (Yes, it's something more general.)
