966 - Vowel Spellchecker\. Medium Given a `wordlist`, we want to implement a spellchecker that converts a query word into a correct word. For a given `query` word, the spell checker handles two categories of spelling mistakes: * Capitalization: If the query matches a word in the wordlist ( **case-insensitive** ), then the query word is returned with the same case as the case in the wordlist. * Example: `wordlist = ["yellow"]`, `query = "YellOw"`: `correct = "yellow"` * Example: `wordlist = ["Yellow"]`, `query = "yellow"`: `correct = "Yellow"` * Example: `wordlist = ["yellow"]`, `query = "yellow"`: `correct = "yellow"` * Vowel Errors: If after replacing the vowels `('a', 'e', 'i', 'o', 'u')` of the query word with any vowel individually, it matches a word in the wordlist ( **case-insensitive** ), then the query word is returned with the same case as the match in the wordlist. * Example: `wordlist = ["YellOw"]`, `query = "yollow"`: `correct = "YellOw"` * Example: `wordlist = ["YellOw"]`, `query = "yeellow"`: `correct = ""` (no match) * Example: `wordlist = ["YellOw"]`, `query = "yllw"`: `correct = ""` (no match) In addition, the spell checker operates under the following precedence rules: * When the query exactly matches a word in the wordlist ( **case-sensitive** ), you should return the same word back. * When the query matches a word up to capitlization, you should return the first such match in the wordlist. * When the query matches a word up to vowel errors, you should return the first such match in the wordlist. * If the query has no matches in the wordlist, you should return the empty string. Given some `queries`, return a list of words `answer`, where `answer[i]` is the correct word for `query = queries[i]`. **Example 1:** **Input:** wordlist = ["KiTe","kite","hare","Hare"], queries = ["kite","Kite","KiTe","Hare","HARE","Hear","hear","keti","keet","keto"] **Output:** ["kite","KiTe","KiTe","Hare","hare","","","KiTe","","KiTe"] **Example 2:** **Input:** wordlist = ["yellow"], queries = ["YellOw"] **Output:** ["yellow"] **Constraints:** * `1 <= wordlist.length, queries.length <= 5000` * `1 <= wordlist[i].length, queries[i].length <= 7` * `wordlist[i]` and `queries[i]` consist only of only English letters.
