Working with Graphs & Trees

What type of tree structure is specialized for string operations?

class Trie {
  constructor() {
    this.root = {};
    this.endSymbol = '*';
  }
  
  insert(word) {
    let current = this.root;
    for (let char of word) {
      if (!(char in current)) {
        current[char] = {};
      }
      current = current[char];
    }
    current[this.endSymbol] = true;
  }
}

Binary Search Tree
Red-Black Tree
Trie (Prefix Tree)
This implements a Trie (Prefix Tree) because: 1) Optimized for string/prefix operations, 2) Each node represents a character in the sequence, 3) Shares common prefixes to save space, 4) Uses endSymbol to mark complete words, 5) Enables efficient prefix-based searches, 6) O(m) insertion and search where m is word length, 7) Common in autocomplete and spell checker implementations, 8) Excellent for dictionary-based applications.
