Get the Height of a Node in a Binary Tree

Objec­tive: Given a binary tree, find the height of a given node in the tree.

Input: A Binary Tree and a node

Out­put: Height of a given node in the tree.


Get The Height Of a Node

Get The Height Of a Node



  • Take a vari­able called height =0.
  • Search for that given node in the tree using recursion.
  • Each time you left or right , increase the height by 1.
  • Once you found the given node, return the height.
  • If till the end you wont find the node, return 0

Com­plete Code:

Output :
Height of the Node 25 is : 3

    There’s some­thing not cor­rect. Height of Node x => 25 should be 1 not 3. Can you check it please?

    • tuto­ri­al­hori­zon

      We are con­sid­er­ing the height here as num­ber of nodes above the par­tic­u­lar node (includ­ing the node itself)

      • sunny kansal

        Still out­put and solu­tion is wrong…Height of Node is the longest path till its leaf node…And it should be 1 for Node 25 not 3…but the num­ber of lev­els are 3…

  • are­fin nowshad

    This code seems like cal­cu­lat­ing depth of a node. Even that is actu­ally wrong, depth should be 2 for Node 25 and height is 1. You cant con­sider the height as the num­ber of nodes above the par­tic­u­lar node includ­ing the node itself as the right way to define height of a node. Because this is out­right wrong.

    yes even in this prob­lem ‚the assump­tion of what is height is con­fus­ing and mis­lead­ing as per the gen­eral standards.
