# 966. Vowel Spellchecker
"""
given a 'wordlist', we want to implement a spellchecker that converts a query
word into a correct word. for a given 'query', the spell checker handles two
categories of spelling mistakes: capitalisation and vowel errors. given some
'queries', return a list of words 'answer' where 'answer[i]' is the correct
word for 'query = queries[i]'
