🚀 LeetCode 211 - Design Add and Search Words Data Structure
In this video, we implement a Trie-based word dictionary that supports both adding words and searching with wildcards using Depth-First Search (DFS).
This Medium-level LeetCode problem is a common interview favorite from top tech companies. Learn how to combine object-oriented design and recursive search logic to solve it efficiently.
🧠 What You'll Learn:
How to implement a Trie in JavaScript
DFS for pattern matching with . wildcard
Design patterns for scalable string data structures
