FAQs

Question: What is a binary tree?
Answer: A binary tree is a hierarchical data structure in which each node has at most two children, referred to as the left child and the right child.

Question: Why is traversal important in binary trees?
Answer: Traversal is essential for accessing and processing the nodes in a binary tree, allowing us to retrieve data in a specific order.
