Binary sort Tree
A self-balancing two-fork sorting tree (binary search tree)The process of generating a two-fork sort tree is very easily unbalanced, and the worst case scenario is one-sided (only right/Zuozi), which results in a much lower retrieval efficiency for the two-fork tree (O (n)).In order to maintain the balance of the binary tree, there are various algorithms, such as: AVL,SBT, stretching tree, treap, red-black tree and so on.
Recently, "Network Security" incidents have occurred frequently in the Internet industry. In August alone, there were a number of cybercriminals ** incidents, including the globelmposter ransomware for many subsidiaries of an important communication company in China ***. About 0.5 billion pieces of data of the hotels of chinacache group were leaked. In the name of cooperation with the operator, the new third board company ruizhi Huasheng illegally stole 3 billion pieces of user data, involving n
ObjectiveThis article will combine JDK1.6 's TreeMap source code, to explore the mystery of red-Haishi together. The red-black tree is an unbalanced problem that solves the two-fork search tree.When inserting (or deleting) a new node, in order to keep the tree balanced, certain rules must be followed, which is the red-black rule:1) Each node is either red or black
Now most stationmaster more or less all know a little seo, can say SEO already gradually popularize. Of course, there is still a relatively distinct level of division, there are high people also have entry-level, but this is only a time accumulation and learning summed up the difference. And we all know, SEO is actually divided into black hat seo and white hat seo (In the meantime mixed with a gray cap, aside). Although many friends may feel that
Originally did not want to talk about black chain this topic, but yesterday in Bowen mentioned my site was hung black chain, simply talk about this topic. There is no doubt that the black chain is also a means of SEO, but it is a black hat technique. Once upon a time, the black
To find a binary tree Insert node:It is known that the nature of the binary tree is that the value of the root node is greater than the value of the left subtree, less than the value of the right subtree, and according to this rule, find the appropriate insertion position for the value to be inserted, and finally insert it:Tree-insert (t,z) {x = root (T); y = null;while (x! = NULL) {y = x;if (Key[z] Red-Black Tree Insert node:Red-
The time complexity of the red/black tree is: O (lgn)SeeMathematical induction"Proves the time complexity of the red and black trees.
Theorem:The height of a red/Black Tree Containing N nodes is mostly 2log (n + 1).
Proof:"The height of a red/Black Tree Containing N nodes is mostly 2log (n + 1 )"Inverse negative pr
Balanced binary tree and red black tree worst case analysis1. Classic Balanced binary treeThe Balanced binary tree (also known as the AVL tree) is a two-fork search tree with equilibrium conditions, with the most common theorem: a balanced binary tree is a two-fork lookup tree with a maximum height difference of 1 for each node of the Saozi right subtree . Because he is a concrete application of the two-fork tree, he also has the properties of a bina
The red and black trees belong to the balanced binary tree. It is not strictly because it does not strictly control the difference between the left and right subtree height or the number of nodes is less than or equal to 1, but the red black tree height remains the average log (n), and the worst case height will not exceed 2log (n).The Red-black tree is a two-for
It has been discussed in the binary tree that if you insert a tree node in random order, the vast majority of them will appear unbalanced. In the worst case, when the data is inserted in order, the binary tree will become a linked list, and the efficiency of insertion and deletion will be severely reduced
is the case of inserting a binary tree in ascending order of data:
A red-black tree is a way to solve a non-equilibrium tree, which is a t
We often encounter computer black screen in work, study or game, make life annoying, but want to solve the problem must find out the reason, for this reason, computer theme House (www.51ztzj.com) summed up a few reasons for everyone's reference.
One, the computer host failure caused by black screen failure:
1. The fault caused by the power supply of the host
The failure of the host power supply or the po
The first serious statement, here said "the following content to enable beginners to learn the principle of black hat", not to let everyone go to the real application, but also to learn the ideas of others, flexible!
"Learning SEO does not need any code base, only need to understand the simple HTML can, will type hair article on the line" see Such an advertising tour, brother smiled, I do not know a code can not understand the SEO in this circle how
First, the conceptThe red and black tree is a binary search tree, which adds a storage bit to each node to represent the node's color, which can be red or black. By constraining the color of each node on a simple path from root to leaf, the red-black tree ensures that no path is twice times longer than the other path, and thus is approximately balanced.Second, th
Abstract: what humans do not know is far more meaningful than what they know. History is never a linear development. Every time we jump forward, there is a "Black Swan. This is what the black swan incident tells us.
The previous article cited the cool and cool term "black swan event", which caused many readers to send messages and let me talk about the
Today, Qingdao SEO received a single, in the communication with customers, the customer specifically stressed that do not use black hat means to improve the site rankings, said that the site will be K, I told him black hat means can be used, but to be divided, to master good skills ... Therefore, today's Qingdao SEO for the use of black hat means to do the optimi
A logic of thinking is that you show the technology is really black enough to the future, well, the future of things always give a person a expensive, not practical feeling, who will be happy to give your Guinea-mouse test. Many 3D printing technologies like the present.650) this.width=650; "src=" http://s4.51cto.com/wyfs02/M02/82/B3/wKioL1deuxjy5l27AABy3nYuTs8942.jpg "title=" 13.jpg "alt=" Wkiol1deuxjy5l27aaby3nyuts8942.jpg "/>Wen/Zhang ShulePublishe
Currently, there are two main causes of computer black screens: hardware faults and software conflicts. The main difference between the two lies in the location of the black screen, that is, black screen at startup, after the machine is started normally, a black screen is displayed during use.
Of course, no matter wh
When I looked at the kernel code in the first half of 2014, the process scheduling used the RB tree. Now, when I analyzed the STL source code, I found that set and MAP also used this data structure, this illustrates the wide application of rbtree, so I spent two days reading it and explained it in three parts. First of all, I want to explain the basic concepts of the red and black trees, next, describe the RB tree iterator in STL, and finally describe
ObjectiveRed and black tree is the most commonly used in the engineering of a self-balanced binary sorting tree, which is similar to the AVL tree, are in the insertion, deletion through a certain adjustment operation to maintain a relatively stable tree height, so as to obtain better query performance.Properties1. The node is red or black.2. The root node is black
About red and black treesRed-black tree is a self-balancing binary search tree, also has the characteristics of a two-fork tree, keeping the right side is always greater than the left node key features. The AVL tree mentioned earlier is also a variant of the binary search tree, which does not reach the height of the AVL tree, in other words, its height is not as high as the AVL tree, but his application is
