Interview Prompt
Implement a MessageFormatter class with a method sort_by_case(text) that regroups the characters of text by letter case, gathering one case run and then the other. Also expose a top-level sort_by_case(text) driver that builds the formatter, runs the method, and returns the resulting string.
Summary
First impressions are formatted carefully.
