How to update the heights of AVL trees?
So, let's update our previous rotation functions so that they also update the changed heights after rotations. As you can see from the above pictures, only the heights of x and y are going to be changed (heights of their ancestors can also change but we will fix them in the insertion process), so will update the heights of x and y only.
How are AVL trees similar to binary search trees?
Similar to red-black trees, AVL (Adelson-Velskii and Landis) trees are also binary search trees which are pretty good balanced. AVL trees use different rules to achieve that balance. AVL trees use balance factor to get a balanced tree.
How does insertion and deletion work in an AVL tree?
Let's learn about the insertion and deletion in an AVL tree. Inserting a new node can cause the balance factor of some node to become 2 or -2. In that case, we fix the balance factors by use of rotations. Also, only the heights of the nodes on the path from the insertion point to the root can be changed.
What is the balance factor for an AVL tree?
For an AVL tree, the absolute value of balance factor for any node can't be greater than 1 i.e., each node must have a balance factor of either -1, 0 or 1. Instead of calculating heights of nodes, again and again, we store the current heights in each node. Look at the following picture.
