It was fate. A crew of Pivots in Portland on the same weekend as the Extra Action Marching Band We just had to seize the opportunity...
Will they be making an appearance at our Beer Night tonight? You never know...
I was just sitting around my living room listening to NPR, and heard the following Car Talk puzzler:
I want you to get a pencil and write down the numbers, 1 - 9, inclusive, and leave enough space between them. At your disposal you have one plus sign and two minus signs. You can insert those plus and minus signs wherever you want, to make the total come out to 100.
Naturally, I thought, "Gee, that would be tedious to solve it by hand. But it would be fun to write a Ruby program to solve it!" 9 minutes later I was sending the result (and the source code) to Car Talk Plaza.
So here's your challenge: can you write a program to solve this puzzle? And can you beat my time?
My solution is below the fold... don't click "more" until you've taken a stab at it yourself.
