What is a Full Binary Search Tree (BST)?

Learn what a Full Binary Search Tree (BST) is and why it's essential for optimizing search efficiency in data structures.

70 views

A Full Binary Search Tree (BST) is a binary tree in which every node has either 0 or 2 children. This structure ensures that the tree is perfectly balanced, optimizing search efficiency. Each level of the tree, except possibly the last, is fully populated with children nodes, making in-order traversal straightforward and effective for searching operations.

FAQs & Answers

  1. What are the characteristics of a Full Binary Search Tree? A Full BST has every node with either 0 or 2 children, ensuring a balanced structure and optimized search performance.
  2. How does in-order traversal work in a Full BST? In-order traversal in a Full BST visits nodes in a sorted order, making it effective for searching through the tree.
  3. What is the difference between a Full BST and a Complete BST? A Full BST has nodes with either 0 or 2 children, while a Complete BST is fully populated at all levels except possibly the last.
  4. Why are Full Binary Search Trees important in computer science? Full BSTs optimize search operations and maintain balanced structures, crucial for efficient algorithm implementations.
