Implement WordFinder class that allows for adding words and searching for them. It has the following methods:
addWord(word: string): Adds a word to the data structuresearch(query: string): Checks if any added word matches the given word. The query can include dots ., which can match any letterThe WordFinder instance will have its methods called with various parameters based on these:
methods: string[]: An array of method namesparams: string[]: An array of stringsmethods[i] will be called with params[i].
Input: methods = ["addWord","addWord","search","addWord","search","search","search"], params = ["car","cat","c.r","dog","d.g","cat","c.."]Output: [null,null,true,null,true,true,true]Explanation: Words 'car' and 'cat' are added, 'c.r' matches 'car', 'dog' and 'd.g' match, 'c..' matches both 'car' and 'cat'.
Input: methods = ["addWord","addWord","addWord","search","search","addWord","search"], params = ["hello","hollow","hollow","hell","hel.o","hero","h.o."]Output: [null,null,null,false,true,null,false]Explanation: The words 'hello', 'hollow' are added, 'hell' doesn't exist, 'hel.o' matches 'hello', 'hero' is added, 'h.o.' does not match with any other word.
Input: methods = ["addWord","search","addWord","search","addWord","search","search"], params = ["bat","b.t","ball","ba.l","bat","b.ll","ball"]Output: [null,true,null,true,null,true,true]Explanation: Words 'bat' and 'ball' are added, 'b.t' matches 'bat', 'ba.l', 'b.ll' and 'ball' match 'ball'.
