Print the counter which will give the number of nodes in the binary tree.

Nothing will be added in the queue because Node 7 has not children.

If Node 7 has left and right child then add them in the queue.

Nothing will be added in the queue because Node 6 has not children.

If Node 6 has left and right child then add them in the queue.

Nothing will be added in the queue because Node 5 has no children.

If Node 5 has left and right child then add them in the queue.

Nothing will be added in the queue because Node 4 has no children.

If Node 4 has left and right child then add them in the queue.

Queue contains currently Node 4, Node 5, Node 6, Node 7.

Node 6 and 7 will get added in the queue.

If Node 3 has left and right child then add them in the queue.

Queue is not empty so remove the node from the queue.

Queue contains currently Node 3, Node 4 and Node 5.

Node 4 and 5 will be added in the Queue.

If Node 2 hasВ left and right child then add them in the queue.

We will get Node 2 with us and increment the counter.

Now Queue is not empty so remove the node from the queue.

Node 2 and 3 will get added in the Queue.

If Node 1 has left and right child then add them in the queue.

We will have Node 1 with us and increment the counter.

Queue is not empty so remove the node from the queue.

If root is not null then add the root in the queue.

The difference between parentElement and parentNode, is that parentElement returns null if the parent node is not an element node: In most cases, it does not matter which property you use, however, parentNode is probably the most popular. Steps involved to find the number of nodes of the above binary tree The parentElement property returns the parent element of the specified element. Add the left and right child of the removed element in the queue.Write a program in Java to find number of nodes of a tree. There are total 7 nodes in a binary tree. We will use a Queue to implement a Java code.

We will create a Java program to find the size of a binary tree by calculating the number of nodes in a binary tree. Write a Program in Java to Find number of nodes of a Tree Pointer right and left will hold the address of right and left child respectively. Node class will have data, right and left. We have to write a program in Java to find the total number of nodes in a binary tree. To reproduce one of this strange behaviors, you can follow the next steps: 1/ Select 2015->A->X node. Total number of nodes in a binary tree is known as a size of a tree. Twitter Facebook LinkedIn Buffer Reddit Tumblr
