The class library can be further used to develop a web based phone directory. The data can also be stored on the client (it is too small) and theTriecan be implemented in JavaScript. 这个类库可以被进一步开发成为一个基于Web的电话目录,数据可以存储在客户端,然后使用JavaScript来实现Trie算法。 Happy Coding! 编程快乐! 原贴地址:http://www.codepro...
/** * Initialize your data structure here. */ var Trie = function() { this.root = new TreeNode(); }; 实现insert方法 /** * Inserts a word into the trie. * @param {string} word * @return {void} */ Trie.prototype.insert = function(word) { let curNode = this.root; let arr ...
Trie Data Structure vs. Alternatives Implementing thecontains()method requires a backing data structure that lets you find elements efficiently, while theisPrefix()method requires us to find the “next greater element”, i.e. we need to keep the vocabulary sorted in some way. We can easily ex...

Autocomplete utility using trie data structure in javascript. A demo is hosted at http://linkm.in/autocompleteweb/ Usage var autoComplete = require('autocompletor'); const opts = { dictionary: 'PATH_TO_DICTIONARY_FILE' }; autoComplete(opts, function(err, dictionary) { dictionary.getWord("hac...
We can use Trie data structure, it is a tree, but not a binary tree. The reuslts of constructing a tree by using the example array data. True of False means whether this letter is the last of the word. We can code it by Javascript: ...
