Web28 mrt. 2024 · Step 1. Create a function that takes the root node, left min node, and right max node. Step 2. Check if the current node’s value is within the limit or not. If not, then return false. Step 3. Go to the left and right subtree by narrowing down the min and max node’s value allowed. Step 4. WebThus, there are two types of skewed binary tree: left-skewed binary tree and right-skewed binary tree. Skewed Binary Tree. 6. Balanced Binary Tree. It is a type of binary tree in which the difference between the height of the left and the right subtree for each node is either 0 or 1. Balanced Binary Tree.
