208. Implement Trie (Prefix Tree) | Leetcode Unlocked - Python
In this video, we break down LeetCode 208: Implement Trie (Prefix Tree), a classic data structure problem essential for coding interviews. Learn how to build a Trie from scratch to handle efficient string insertions and prefix searches, the exact logic behind features like autocomplete and spell checking. I explain the conceptual difference between Tries and Binary Trees, walk through a visual example, and provide a clean, step-by-step Python implementation. We also cover time and space complexity analysis (Big O) and discuss edge cases. Stick around for full solution code in Java, C++, and JavaScript at the end!
