Ok, for those who may have been following but haven't quite figured out the one I've posted, here's a solution. It's a simple error correcting code.

The dwarves agree that the last dwarf will...

Can the dwarves exist in 50 dimensional space and the line be a 49-dimensional hyperplane?

Dwarves can not trade hats either.

Sebastiani has a correct strategy for saving half of the...

Since Snafuist posts all of the riddles he doesn't get the fun of trying to solve them. Here's one you guys may enjoy, the solution is more computer sciency than you might think ;)


Every year in...

>I'm planning to write an article about the whole story to improve my English skills. Is this stuff somehow appealing to non-mathematicians?


I'd read it. I was actually planning on taking a...

They are not equivalent if I remember correctly. (a < b) will return 0 if false and something non-zero otherwise (but not necessarily 1). The original program returned 1.

There's a whole book of these problem called Knights and Knaves, something like this:

Knights always tell the truth and Knaves always lie....
