Height Of Binary Tree

96

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));
}

Height Of Binary Tree -


height(10) = max(height(5), height(30)) + 1

height(30) = max(height(28), height(42)) + 1
height(42) = 0 (no children)
height(28) = 0 (no children)

height(5) =  max(height(4), height(8)) + 1
height(4) = 0 (no children)
height(8) = 0 (no children)
