In 1962, G.M Adelson-velsky and E.M Landis invented the tree, so it was also called the AVL tree. Balanced binary tree requirements for each node, its left and right sub-tree height difference can not exceed 1, if the insertion or deletion of

The associative container is said to be an associative container, each data has a key value and a real value, when the element inserts the associative container, the container according to the key value size, according to the specific rule (Set,multiset,map,multimap is the red black tree, Hash is a hash table) to place the elements in a specific location, so the associative container will not have push_back () Pop_back () Push_front () Pop_front () and other operations; First, take a look at th

04-Tree 5 Root of AVL Tree (25 min) An AVL tree is a self-balancing binary search tree. In a AVL tree, the heights of the subtrees of any node differ by at the most one; If at any time they differ by more than one, the rebalancing is the done to restore this property. Figures 1-4 illustrate the rotation rules. Now given a sequence of insertions, you is supposed

Finally, the Non-Recursive Implementation of the AVL Tree Insertion routine is completed. I started to access the AVL Tree the day before yesterday. Today I used a day to complete the non-recursive insertion routine. it should be 6 hours. even if the test is correct, you are willing to review and understand it in this form. I also want to display it, because in my opinion, it is amazing to write a non-recur

AVL is a balanced binary tree that rotates the binary search tree by rotating the nodes in the two-fork search tree to achieve a balance. AVL has the highest balance in all balanced binary search trees.definitionA balanced binary tree or an empty tree or a two-fork search tree that satisfies the following properties: The difference in the height of the left and right subtrees is no more than

When it comes to CAD, I think of the things I learned about CAD. At that time I did not know CAD, and friends are learning interior design, need to complete the CAD operation. At that time I went to find her to play, asked her to draw cad there, immediately feel very interes

Rotation operation:Since any one node has a maximum of two sons, it can only be caused by the following four cases when the height is unbalanced:1. A single insertion of the left subtree of the left son of the node was made.2. The right subtree of the left son of the node was inserted once.3. An insert was made to the left subtree of the right son of the node.4. An insert was made to the right subtree of the right son of the node.After inserting a node into the

A balanced binary tree is an evolutionary body of a binary search tree and the first binary tree that introduces the concept of balance. In 1962, g.m. Adelson-velsky and E. M. Landis invented the tree, so it is also called the AVL Tree. For each node, the height difference between the left and right Subtrees cannot exceed 1. If a node is inserted or deleted, the height difference must be greater than 1, it is necessary to rotate between nodes and main

AVL Tree rotation, The balanced binary tree may be unbalanced during the insert operation. AVL is a self-balanced binary tree, which re-balances the binary tree by rotating unbalanced nodes, in addition, the average and worst case time complexity of search, insert, and delete operations is O (log n) There are four types of AVL Tree rotation. Note that all rotati

The AVL tree is a two-fork search tree with equilibrium condition, the time complexity of finding and deleting is logn, and the improvement of the two-fork search tree, we call the difference of the Saozi right subtree depth of the node as the Balance factor (BF), in which the absolute value of the balance factor of each node is not greater than 1.A subtree that is closest to the insertion node and that has an absolute balance factor greater than 1 is

I. Balanced Binary Tree features:The balanced binary tree was first proposed by Adelson-velskii and Landis in 1962. It is also called the AVL Tree.Definition: a balanced binary tree, an empty tree, or a binary sorting tree of the following properties:(1) the absolute value of the difference between left and right subtree depth cannot exceed 1;(2) Left and Right Subtrees are still balanced binary trees.Balance factor: BF = left subtree depth-right subt

In the previous article (AVL Tree insertion and deletion Search Algorithm Implementation and analysis-1 (balanced factor method, this article describes how to use a balance factor to record the height difference between left and right Subtrees to implement AVL Tree insertion, deletion, and search algorithms, and analyzes some defects of this method. Here, I will use another method to implement these algorit

Performing an insert operation can be unbalanced when balancing a binary tree. AVL This tree is a self-balancing binary tree that balances the two forks once again. And the Find, insert, and delete operations are O (log n) in the average and worst case time complexityThere are four scenarios in which the AVL tree rotates in a common way. Note that all rotations are carried out around the first node that mak
