Height of a Binary Tree is a number of edges between the tree's root and its furthest leaf. For example, the height of the following binary tree is 2

A tree consisting of only a single node has a height of 0


Find height or maximum depth of a given binary tree


Using recursive/top-down algorithm, height(root node) = max (height(left subtree of root node), height(right subtree of root node)) + 1 and so on
