get binary tree height java code example

Example 1: find height of binary search tree python

def getHeight(self,root):
        return -1 if root is None else 1 + max(self.getHeight(root.left), self.getHeight(root.right))

Example 2: height of a binary tree

int height(Node* root)
{
    // Base case: empty tree has height 0
    if (root == nullptr)
        return 0;
 
    // recur for left and right subtree and consider maximum depth
    return 1 + max(height(root->left), height(root->right));
}
