Binary Tree: A tree whose elements have at most 2 children is called a binary tree. Since each element in a binary tree can have only 2 children, we typically name them the left and right child. Binary Tree Representation in C: A tree is represented by a pointer to the topmost node in tree.

If the tree is empty, then value of root is NULL. A Tree node contains following parts. Data 2. Pointer to left child 3. Pointer to right child In C, we can represent a tree node using structures. Below is an example of a tree node with an integer data.

A Python class that represents an individual node. Node left, right;. Node int val. Node root;. This is a guide to Binary Tree Program in C. Here we discuss the Introduction, syntax, Types of Binary Tree with Examples with code implementation. You may also have a look at the following articles to learn more —. Submit Next Question.

The logical representation of the above tree is given below: In the above tree, node 1 contains two pointers, i. Properties of Binary Tree At each level of i, the maximum number of nodes is 2 i. The height of the tree is defined as the longest path from the root node to the leaf node.

The tree which is shown above has a height equal to 3. If the number of nodes is minimum, then the height of the tree would be maximum. Conversely, if the number of nodes is maximum, then the height of the tree would be minimum. If there are 'n' number of nodes in the binary tree. Let's look at the simple example of the Full Binary tree. Properties of Full Binary Tree The number of leaf nodes is equal to the number of internal nodes plus 1. In the above example, the number of internal nodes is 5; therefore, the number of leaf nodes is equal to 6.

The maximum number of nodes is the same as the number of nodes in the binary tree, i. Let's create a complete binary tree. The minimum number of nodes in complete binary tree is 2 h. The maximum height of a complete binary tree is Perfect Binary Tree A tree is a perfect binary tree if all the internal nodes have 2 children, and all the leaf nodes are at the same level.

Let's look at a simple example of a perfect binary tree. Note: All the perfect binary trees are the complete binary trees as well as the full binary tree, but vice versa is not true, i.
