Problem Statement
A trie (pronounced as 'try') or prefix tree is a tree data structure used to efficiently store and retrieve keys in a dataset of strings. Implement the Trie class with insert, search, and startsWith methods.
Real Engineering Applications
In production systems, this concept directly maps to caching index layers, route lookups optimizations, compiler scope parsing validations, and multi-thread dependency schedulers.
