AVL tree is a height-balanced binary search tree. That means, an AVL tree is also a binary search tree but it is a balanced tree. A binary tree is said to be balanced if, the difference between the heights of left and right subtrees of every node in the tree is either -1, 0 or...
In the above example, we have inserted a new node 10 to the left of left to node 30. We can see that after inserting a new node the balance factor of node 30 becomes 2 and the tree becomes unbalanced. To make this tree balanced tree we will apply LL Rotation on the tree. We will...
AVL tree stands for Adelson, Velskii & Landis Tree, and it can be explained as an extension of the binary search tree data structure. Though it’s similar to a binary search tree, there is one highlight of a difference that is the height of the tree value should be <=1, and unlike ...

所以AVL Tree是平衡的,其高度是h=lgN; 在AVL Tree中,每一个node的高度等于取其2个child node 的较大的高度值加1,即max[left child height, right child height]+1; 若node==NULL,则其高度默认为-1. 当在构建AVL Tree的过程中,向其中insert node的时候,首先第一步跟BST insert一样,然后第二步是要检查...

By switching to an AVL, data is balanced in the tree and the search time is decreased to log n.So it is more efficient in most cases to use the AVL tree, below is an example of how to code this in C++. Note that the AVL tree uses a lot of the same code the BST did from ...
