Find the Deepest Node in a Binary Tree.

Objective: - Given a binary tree, write an algorithm to Find the deepest node in it.


  • Take two global variables as "deepestlevel" and "value".
  • starting with level=0, Do the inorder traversal and whenever you go down one level ( root.left OR root.right), increase the level by 1.
  • Keep checking if deepestlevel < level, if yes then update the "deepestlevel " and "value ".
  • At the end return "value", which will be the deepest node value.
  • See the code for a better explanation.


Deepest child is: 8
