LEETCODE 208 : TRIE DATA STRUCTURE IMPLEMENTATION: C++

LeetCode Problem 208, "Implement Trie (Prefix Tree)," involves designing a trie to efficiently store and retrieve keys in a dataset of strings. This advanced data structure supports `insert`, `search`, and `startsWith` operations. The trie optimizes these operations by structuring data in a tree-like form, where each node represents a character of a word. Insertion and search are performed by traversing down the tree from the root through relevant nodes for each character in the string. The `startsWith` function checks prefixes by similar traversal, stopping when the prefix ends. This structure dramatically reduces the time complexity for search operations compared to a naive list implementation, making it highly efficient for tasks involving large sets of string data, such as autocomplete features.
