27 is leaf node leaf have no more child . We use cookies to ensure you have the best browsing experience on our website. We need to find the number of edges between the tree's root and its furthest leaf to compute the height of tree. The depth is a measure of how far a node is from the root of the tree.

The depth of a node is the length of the path to its root. Attention reader! The minimum depth is the number of nodes along the shortest path from the root node down to the nearest leaf node. And if the right subtree is NULL, then recur for the left subtree. Steps to find height of binary tree. Thanks to Gaurav Ahirwar for providing above solution. So, the time complexity is O(N) where N is the number of nodes in the tree. The height of the root node of the binary tree is the height of the whole tree. Comment down below if you have queries related to height and depth of binary tree. Given a Binary Tree and a key, write a function that returns level of the key. If not leaf node then if the left subtree is NULL, then recur for the right subtree. The depth of a particular node in binary tree is the number of edges from the root node to that node. Get The Height Of a Node. The height of the root is the height of the tree. Find the maximum depth of left sub-tree recursively. first traverse to left side so next node is 27. Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. we respect your privacy and take protecting it seriously. Time complexity of above solution is O(n) as it traverses the tree only once. Input Format: The first line of input contains an integer T denoting the number of test cases. code. The depth of binary tree is the depth of the deepest node (leaf node). Given a binary tree, find its minimum depth. For example, the minimum height of below Binary Tree is also 2. He spend most of his time in programming, blogging and helping other programming geeks. Your email address will not be published. The length of the longest path from the root of a binary tree to a leaf node is the height of the binary tree. Required fields are marked *. Intern at OpenGenus (2019) | Bachelor of Technology (2017 to 2021) in Information and Communication Technology at Ahmedabad University, With HTML5 file API it is possible for JavaScript to process a file locally, e.g. 30 have both left and right node .
