A Binary Tree is a tree data structure where each node has at most two children referred to as the left and right child. A Binary Search Tree (BST) is a specific type of binary tree that maintains the order: for any node, all values in its left subtree are less, and all values in its right subtree are greater. This ordering property makes BST efficient for search operations.

FAQs & Answers

  1. What are the main characteristics of a binary tree? A binary tree has a hierarchical structure where each node can have at most two children, known as the left and right child.
  2. How does a binary search tree differ from a regular binary tree? A binary search tree enforces an ordering of its elements, where the left child's values are less than the node's value, and the right child's values are greater.
  3. Why is a binary search tree more efficient for searching? The ordered structure of a BST allows for faster search operations, as it reduces the number of comparisons needed to find a value compared to an unstructured binary tree.
