Class MagicDictionary

java.lang.Object

public class MagicDictionary
extends Object

676 - Implement Magic Dictionary.

Medium

Design a data structure that is initialized with a list of different words. Provided a string, you should determine if you can change exactly one character in this string to match any word in the data structure.

Implement the MagicDictionary class:

• MagicDictionary() Initializes the object.
• void buildDict(String[] dictionary) Sets the data structure with an array of distinct strings dictionary.
• bool search(String searchWord) Returns true if you can change exactly one character in searchWord to match any string in the data structure, otherwise returns false.

Example 1:

Input

[“MagicDictionary”, “buildDict”, “search”, “search”, “search”, “search”] [[],

"leetcode", [“hello”], [“hhllo”], [“hell”], [“leetcoded”]]

Output: [null, null, false, true, false, false]

Explanation:

MagicDictionary magicDictionary = new MagicDictionary(); 
magicDictionary.buildDict(["hello", "leetcode"]); 
magicDictionary.search("hello"); // return False 
magicDictionary.search("hhllo"); // We can change the second 'h' to 'e' to match "hello" so we return True 
magicDictionary.search("hell"); // return False 
magicDictionary.search("leetcoded"); // return False

Constraints:

• 1 <= dictionary.length <= 100
• 1 <= dictionary[i].length <= 100
• dictionary[i] consists of only lower-case English letters.
• All the strings in dictionary are distinct.
• 1 <= searchWord.length <= 100
• searchWord consists of only lower-case English letters.
• buildDict will be called only once before search.
• At most 100 calls will be made to search.
