FAQs

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

Question: How do I implement a binary tree traversal in C++?
Answer: You can implement traversals using recursive functions that visit nodes in a specific order: in-order, pre-order, or post-order.

Question: Why are binary trees important in competitive exams?
Answer: Binary trees are foundational in computer science and are often used in algorithms, making them a common topic in exams.
