Oh, and you should in theory analyse the algorithms you're using to see if
there are better ones first, but given your task, the 'naive' algorithms
(which isn't insulting, that means the ones you're most likely to come up
with on a first try) are basically as good as you can do on such small
input. (It's the string operations that need optimization then, and
Python's are pretty good, as you'd expect.) So I didn't mention that.

(About the worst you could do is do something in quadratic time that
should be linear. There are some subtle ways of doing that in Python. But
with small input sizes, it doesn't matter much.)
