Because you optimized a brute force-algorithm for speed, without first 
fixing the algorithm (first and foremost the ability to vary "k"). It 
seemed that the ability to use large n-s, however, somehow was of paramount 
importance, and you even suggested that Donovan use a rather obscure 
technique to vary k.

Your latest algorithm is great, though, and I wish you had posted it the 
first time around. I find it to imortant when explaining algorithms to 
beginners that extensibility and generality of the algorithm should be 
taken care of before speed. When I find myself in a position where I need 
to unroll loops (or even get rid of recursion), I'm already reprogramming 
the algorithm in C++.
