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: Why is traversal important in binary trees? Answer: Traversal allows us to access and manipulate each node in the tree, which is essential for various algorithms and operations.
Question: How can I improve my understanding of binary trees in C++? Answer: Regular practice with MCQs and coding exercises will help solidify your understanding and improve your implementation skills.

Q. What is the output of an in-order traversal of the binary tree with root 1, left child 2, and right child 3?
A.
1, 2, 3
B.
2, 1, 3
C.
3, 1, 2
D.
1, 3, 2
Solution
In in-order traversal, we visit the left child first, then the parent, and finally the right child. Thus, the output is 2, 1, 3.
Q. What is the result of a post-order traversal on a binary tree with nodes 1, 2, and 3, where 1 is the root, 2 is the left child, and 3 is the right child?
A.
1, 2, 3
B.
2, 3, 1
C.
3, 2, 1
D.
1, 3, 2
Solution
In post-order traversal, we visit the left child, then the right child, and finally the parent. Thus, the output is 2, 3, 1.
