Wow, now it's really hit home for me how much programming languages and libraries
have advanced in the past 20 years.  Nowadays any reasonable person would
generally use a hash table even for small N because it's not any harder to code.
Any modern language worth its salt comes with one either built in or in the
standard lib.  I guess 20 years ago this wasn't so.
