Most frequent words
A word is a maximal run of ASCII letters (a–z, A–Z); everything else separates words. Words are compared case-insensitively and returned in lowercase. Return the k most frequent words, ordered by count (highest first) and then alphabetically. If there are fewer than k distinct words, return all of them.
