FAQs
Question: What is the time complexity of in-order traversal? Answer: The time complexity of in-order traversal is O(n), where n is the number of nodes in the binary tree.
Question: How can I differentiate between a complete and a full binary tree? Answer: A full binary tree has all nodes with either 0 or 2 children, while a complete binary tree is filled at all levels except possibly the last, which is filled from left to right.

Q. If a binary tree has a height of h, what is the maximum number of nodes it can have?
A.
2^h - 1
B.
2^h
C.
h^2
D.
h!
Solution
The maximum number of nodes in a binary tree of height h is 2^h - 1, which occurs in a complete binary tree.
Q. Which traversal method of a binary tree can be used to retrieve nodes in non-decreasing order?
A.
Pre-order
B.
Post-order
C.
In-order
D.
Level-order
Solution
In-order traversal visits the left subtree, the root, and then the right subtree, which results in nodes being retrieved in non-decreasing order for binary search trees.
