FAQs

Question: What are the main types of Binary Trees?
Answer: The main types include Full Trees, Complete Trees, and Perfect Trees, each with distinct properties.

Question: How do I differentiate between In-order and Pre-order traversal?
Answer: In-order traversal visits nodes in the order of left child, root, and right child, while Pre-order visits in the order of root, left child, and right child.
