Identifying BST (Binary Search Tree): To determine if a tree is a BST, check if each node's left child is less than the node and its right child is greater. Perform an in-order traversal; if you get a sorted sequence, the tree is a BST. Ensure each subtree also meets these conditions.

FAQs & Answers

  1. What are the properties of a Binary Search Tree? A Binary Search Tree must have the left child less than the node and the right child greater.
  2. How do you perform an in-order traversal? An in-order traversal involves visiting the left subtree, the node, and then the right subtree in that order.
  3. Why is it important to identify a BST? Identifying a BST helps ensure efficient data operations such as search, insert, and delete.
  4. What are common applications of Binary Search Trees? BSTs are commonly used in databases, search algorithms, and maintaining sorted data.
