DSA Introduction What is an algorithm? Related Topics Perfect Binary Tree. Tree Traversal - inorder, preorder and postorder. AVL Tree In this tutorial, you will learn what an avl tree is. This type of rotation is identified when a node has a balanced factor as -2, and its right-child has a balance factor as Insert operation is almost the same as in simple binary search trees. After every insertion, we balance the height of the tree.

Insert operation takes O log n worst time complexity. In the above example, insert Step 2 : Once the node is added, the balance factor of each node is updated. After is inserted, the balance factor of every node is updated. Step 3 : Now check if any node violates the range of the balance factor if the balance factor is violated, then perform rotations using the below case.

In the above example, the balance factor of is violated and case 1 becomes applicable there, we perform LL rotation and the tree is balanced again. Deletion is also very straight forward. Thank me later. Do you have the solution? Inorder display isn't working, we can print each node by storing it, why is that? Sign up for free to join this conversation on GitHub.
