Re: Compare and sort one array according to another.
You have said that the size of your two arrays is small, so the fact that
the find_index based solution is o(n^2) probably doesn't matter. For
kicks, a o(n) solution compared to the o(n^2) solution here:
https://gist.github.com/seifertd/5800639
It involves precomputing a lookup index for the data you need to sort.
