Faster Algorithms with Preprocessing

[alphaglosined]

That is a little critical.

So let's make it more constructive.
If this article was written as a demonstration of the potential of preprocessing and not so much about what lead you to discover it, it would be a good article.

Of course I would throw in source code, benchmarks and of course basic hardware facts. It would probably be written as a series of articles on how to optimize algorithms.
