Trie (Prefix Tree) Fundamentals
Binary trees consist of nodes where each node holds a value and pointers to left and right children:
struct Node {
int value;
Node* left;

Implementing a Trie Data Structure for Prefix-Based String Operations
Core Structure
Root node: An empty node serving as the entry point; its children represent the first characters of stored strings.
Internal nodes: Represent intermediate characters in strings.
Leaf nodes: Mark the end of a valid word via a boolean flag, evenif they have children (e.g., "do" and "dog" can coexist).
