What is Implement Trie?
Build a trie data structure that supports inserting a word, searching for an exact word, and checking if any word starts with a given prefix. Each node stores a map of child characters and a flag marking word endings. This problem teaches you the trie structure itself, which is prerequisite knowledge for all harder trie problems.
