Rebalance avl tree

WebbTo balance itself, an AVL tree may perform the following four kinds of rotations − Left rotation Right rotation Left-Right rotation Right-Left rotation The first two rotations are single rotations and the next two rotations are double rotations. To have an unbalanced tree, we at least need a tree of height 2. WebbIn order to rebalance the tree, we start at the node inserted and travel up the tree, balancing each and every node of the tree if needed. Left Right Rotations In this rotation operation, …

Webb19 juni 2015 · Yes, the tree should update as soon as the balance factor is smaller than -1 or greater than 1, so it can never be more than -2 or 2. I did change it, though, just now to see if that made a difference. But it didn't and I'm still failing those three tests :/ – Riana Jun 19, 2015 at 3:04 Show 6 more comments question via email Twitter Facebook.

However, from your comments, it sounds like you may have some other options: You say that you want a BST instead of a list for O (log n) searches. If searching is all you need and your data are already sorted, the bisect module provides a binary search algorithm for lists.

WebbEfficient rebalancing is the key to making the AVL Tree work well without sacrificing performance. In order to bring an AVL Tree back into balance we will perform one or more rotations on the tree. To understand what a rotation is let us look at a very simple example. Consider the tree in the left half of Figure 3.
