Code – Trie
Hey there, coders! Let’s dive into Tries (pronounced “try”), a fascinating and efficient tree-like data structure. Think of them as super-powered prefix trees, perfect for tasks like auto-completion, spell-checking, and fast string searching. Don’t worry if they sound a bit intimidating at first – we’ll break down everything you need to know in a clear and friendly way, so you’ll be building your own Trie applications in no time!
Trie – Theory
A Trie efficiently stores and retrieves strings by organizing them into a tree-like structure where each path represents a unique word, leveraging shared prefixes for space optimization.

Trie – Problems
While efficient for prefix-based searches, tries can consume significant memory, especially with large datasets or many long strings.
