 /**
+ * 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 word, the spell checker handles two categories of spelling mistakes:
@@ -15,20 +17,36 @@
  * 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"]
+ *
+ * Note:
+ *
+ * 1 <= wordlist.length <= 5000
+ * 1 <= queries.length <= 5000
+ * 1 <= wordlist[i].length <= 7
+ * 1 <= queries[i].length <= 7
+ * All strings in wordlist and queries consist only of english letters.
