The AVL tree is the first self-balancing Binary Search Tree invented. Its time complexity for addition, deletion, and query is O (logn), which is a very efficient data structure. The AVL tree is very suitable for scenarios such as frequent search and frequent addition and deletion. [Blog: http://blog.csdn.net/thisinnocence] AVL Tree was born in 1962 and was inven

Reference Link: http://blog.csdn.net/cjbct/article/details/53613436 The most important thing in the AVL tree is to rebalance the tree, which we call a process of rotation. The rotation consists of four kinds, mainly due to the insertion position. The process of rotation can be seen in the comments section of the code (569 lines-639 lines), with a detailed explanation. In this writing process, the C + + template class definition and function impleme

Introduced:In computer science, AVL trees are the first to invent self-balancing binary search trees.The height of the two subtrees of any node in the AVL tree is the maximum difference of one, so it is also called a height-balanced tree.Find, insert, and delete are O (log n) in both the average and worst case scenarios. Additions and deletions may require one or more tree rotations to rebalance the tree. T

Why did Linux use the AVL tree earlier and then prefer the red-black tree?In fact, this is a result of the usefulness of the red and black trees, this essay is still a metaphysical point of view. Red and black trees can be exported directly from 2-3 trees. We can not mention the red and black trees, but only 2-3 trees. Since the operation of the 2-3 tree is too simple. In addition, whatever the operation and characteristics of the red-black tree can b

large range, not only indicates the AVL Tree, because the balance of the tree is not an absolute measurement standard. The general significance of "balance" is that no node is too deep (the depth is too large), and different balancing conditions correspond to different tree types, which also shows different efficiency. There are many types of balanced binary trees, such as AVL-tree, Rb-tree, and AA-tree. B

Balanced binary sorting treeBalanced binary sorting tree (Balanced binary sort trees), previous blog "Data structure" binary sort tree BST spoke BST, and at the end we said that the operation on BST would not exceed O (h), since tree height is so important, So Bbst's study is to make the depth of the tree reach O (LGN) within an acceptable range.n nodes of the two-tree, the height of the LGN to remove the time limit, the tree is ideal balance, meet such conditions of the tree only a complete bin

The binary lookup tree may be N-1 in the worst case, that is, the element inserted after inserting the element is always larger or smaller than the previously inserted element. To solve this imbalance, the equilibrium condition was introduced to limit the depth of the nodes in the tree, the oldest of which is called the AVL tree. This tree limits the height of the left and right subtrees of each node in the tree to no more than one. (another stricter

AVL TreeIs the first self-balancing Binary Search Tree. The height of the two Subtrees on any node in the AVL tree is the largest difference, so it is also called the height balancing tree. Search, insert, and delete are both O (LogN). Adding or deleting a tree may require one or more tree rotations to rebalance the tree. The AVL Tree is named after its inventor

1 Introduction The role of CAD has been agreed upon. But the actual benefit of the play, in different areas of the gap is very large, especially the introduction of high-end CAD workstation system development and application, the gap is even greater. At present, some new concepts have appeared in the application and popularization of CAD technology, and some new

The AVL tree is a highly balanced two-fork search tree, with the height of the left and right trees of each node not greater than 1. This nature makes the search efficiency of the AVL tree higher than the average two-fork search tree, because for a set of incrementing arrays, the two-fork search tree is a linked list, the search time complexity is naturally o (n), and its composition of the
