Data Structures and Algorithms — Trees

Trees are hierarchical data structures with nodes connected by edges. Common types include binary trees, binary search trees, and AVL trees. They're used in databases, file systems, and AI.

// Basic Binary Tree Node
class TreeNode {
  constructor(value) {
    this.value = value;
    this.left = null;
    this.right = null;
  }
}
const root = new TreeNode(10);
root.left = new TreeNode(5);
root.right = new TreeNode(15);
