# Minimum number of nodes in a complete binary tree

The above binary Tree is a complete binary tree and has number of nodes = 4. Solution: In a complete binary tree every level, except possibly the last, is completely filled, and all nodes in the last level are as far left as possible. A complete Binary Tree can have between 1 and 2 h nodes inclusive at the last level h. So, the properties of complete Binary tree is: All levels are filled up except the last level A tree has maximum nodes if all levels have maximum nodes. So maximum number of nodes in a binary tree of height h is 1 + 2 + 4 + .. + 2 h-1. This is a simple geometric series with h terms and sum of this series is 2 h – 1. In some books, height of the root is considered as 0. In this convention, the above formula becomes 2 h+1 – 1 3) In a ...
