We use [lexicographical
order](https://en.wikipedia.org/wiki/Lexicographical_order) here, `Given two
different sequences of the same length, a1a2...ak and b1b2...bk, the first one
is smaller than the second one for the lexicographical order, if ai<bi (for the
order of A), for the first i where ai and bi differ.`
