yeah, i got one in my Mensa magazine last month, it's pretty funny. my favorite question is "This space is left blank. Improve upon it." I considered sending it in, but it's been years since my programming days-- i don't have what it takes. Still, great recruiting technique.

I can't believe someone got the question:

How the dickens did anyone get this? Where did they get the numbers? I was still trying to figure out what they were asking!

Its not so much where you are as when you are.

Its a common thing in Games magazine. Every letter maps to a different digit, a simple substitution cypher. Then you have to work out what combination of numbers yields a valid solution. A brute force attack is generally the way to solve it. After all there are only 10! combinations

^^Yeah, I got that one as well.

And by brute force method, you mean guess and check?

Actually, I think you'd be able to write a progam to solve that, easily.

you know they do (or did, dunno) have questions like that on the SAT I. Except its much easier. Like AB + 9C = 1E3, no two letters can have the same value, et cetera.

You know - it's at times like this that I realise my brain has turned to mush.

I did algebra and calculus at school etc - I got an A grade. I could look at some of these problems and figure out an equation to solve em etc.

I looked at my cousin's basic calculus paper the other day, gobbledegook...

Brute force is programming technique where you plug in every allowable combination until you find one that works.
