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:
wordlist = ["yellow"]
, query = "YellOw"
: correct = "yellow"
wordlist = ["Yellow"]
, query = "yellow"
: correct = "Yellow"
wordlist = ["yellow"]
, query = "yellow"
: correct = "yellow"
('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.\n\twordlist = ["YellOw"]
, query = "yollow"
: correct = "YellOw"
wordlist = ["YellOw"]
, query = "yeellow"
: correct = ""
(no match)wordlist = ["YellOw"]
, query = "yllw"
: correct = ""
(no match)In addition, the spell checker operates under the following precedence rules:
\n\nGiven some queries
, return a list of words answer
, where answer[i]
is the correct word for query = queries[i]
.
\n
Example 1:
\nInput: wordlist = [\"KiTe\",\"kite\",\"hare\",\"Hare\"], queries = [\"kite\",\"Kite\",\"KiTe\",\"Hare\",\"HARE\",\"Hear\",\"hear\",\"keti\",\"keet\",\"keto\"]\nOutput: [\"kite\",\"KiTe\",\"KiTe\",\"Hare\",\"hare\",\"\",\"\",\"KiTe\",\"\",\"KiTe\"]\n
Example 2:
\nInput: wordlist = [\"yellow\"], queries = [\"YellOw\"]\nOutput: [\"yellow\"]\n\n
\n
Constraints:
\n\n1 <= wordlist.length, queries.length <= 5000
1 <= wordlist[i].length, queries[i].length <= 7
wordlist[i]
and queries[i]
