Structure of a Trie

Explore the basic structure of a Trie data structure and learn how to build it using JavaScript. Understand the role of Trie nodes representing alphabets, pointers to children, and how to mark the end of words. This lesson helps you grasp the implementation details needed for efficient insertion and search operations in Tries.

We'll cover the following...

Introduction

In this lesson, we will take a look at the basic structure of a trie and then build a class in JavaScript based on what we’ve studied.

g t t o o t->o h h t->h p p o->p u u h->u e e h->e s s u->s i i e->i r r i->r Root Root Root->t
Trie containing "top", "thus" and "their".

The Trie Node Class

The Trie node represents one alphabet, which keeps pointers to its children nodes. For example, if we want to ...
