Problem

A document editor lines up the original and edited version of a sentence so a reviewer can see what changed. Given the two versions as `sentence_a` and `sentence_b`, split each on whitespace and return the words present in exactly one version, with `sentence_a`'s uniques listed before `sentence_b`'s.

Summary

Two versions of the same line. Surface only what changed.
