Implementing a Trie
Explore how to implement a trie data structure with key operations like word insertion, searching full words, and prefix matching. Understand the structure of trie nodes, marking word endings, and traverse methods for effective search and insertion. This lesson equips you with practical coding techniques to build tries in C++ or Java and apply them for efficient string retrieval tasks.
Tries
A trie data structure is utilized for searching or retrieving data. The most critical and frequent operations involved in a trie data structure are:
Insertion of a word.
Searching for a word/prefix.
Implementing tries
Let's begin implementing a trie class with given functions.
Trie(): This initializes the trie object.void insert (String word): This inserts the string word into the trie.boolean search (String word): This returnstrueif the string word ...
