Explanation of Solution

Binary tree:

A complete binary tree is a binary tree with the property that every node must have exactly two children, and at the last level the nodes should be from left to right.

Root node:

  • First node must be the root of the tree.
  • The second node must be the left child of the root
  • The third node must always be the right child of the root.
  • The next node must start to fill the next level from left to right.

The diagrammatic representation of binary tree is as follows:
