First, Introduction Balanced binary tree (balancedbinary or height-balanced) Also known as the AVL tree. It is either an empty tree or a two-fork tree with the following properties: Its Saozi right subtree is a balanced binary tree, and the Saozi of the depth of the right subtree does not exceed 1. If the balance factor BF (Balancefactor) of the node in the two-fork tree is defined as the depth of the left subtree of the node minus the depth of its right subtree, the balance factor of all node

, which is caused by the knots inserted on the left Tree of the right subtree of A. It also needs to be rotated twice (clockwise first and then counterclockwise) to restore the balance. Similar to the AVL Tree mentioned earlier, the red/black tree maintains a balance between the binary search tree through specific operations during the insert and delete operations to achieve high search performance. Since the emergence of the red/

The height expectation of a randomly constructed two-fork lookup tree is O (LGN), and does not mean that all two-fork lookup trees have a height of O (LGN). But for some binary search tree deformation, the performance of the basic operation of the dynamic set is always very good, such as red black tree, B-tree, balanced binary tree (AVL tree), jumping table (not the exact tree, more or less the structure of the tree), treaps (tree heap) and so on. Her

In the day of intimate contact with the computer, we often encounter the phenomenon of black screen display, encountered this phenomenon most people will be conditioned to think that their display must be damaged, the rest of their work is to ask professionals to repair the monitor. In fact, not all black screen phenomenon is caused by the display itself, there are some operational details will lead to the

Red-black tree is a very good performance data structure, the key is that it can ensure that the worst performance is also logarithmic, mainly because it is a balanced tree, so also called the balance of the search tree. To understand the red and black trees, it's best to take a look at my previous blog, "Algorithm 4" symbol table and the two-fork lookup tree, to understand the binary lookup tree and why we

Http://www.cnblogs.com/CarpenterLee/p/5503882.htmlThis article takes Java TreeMap as an example, from the source code level, combined with detailed illustrations, silking the insertion, deletion and the resulting adjustment process of the red-black tree (red-black trees).General IntroductionJava TreeMap implements the SortedMap interface, which means that the key elements in the Map are sorted in order of s

The probability of the beauty of programming: a bucket with white balls, black balls each of 100, now according to the following rules to take the ball: I, each time from the inside out two balls; II, if you take out two of the same color ball, then put a black ball, II, if the removal of two different colors of the ball, And put a white ball in it. Q: What is the probability that there is only

Black Kat This term to love shooting scenery theme of the friend is not unfamiliar, and even Google has dozens of on the Black Kat of teaching, which resources are not scarce, but some predecessors wrote is indeed some esoteric, for a time to let the novice understand that there is a certain degree of difficulty, If it can be simpler and some common questions can be solved together, it should be able to mak

Black Hat seo, has been a minefield that you seoer dare not touch. In many black hat SEO techniques, can be in search engines to get a better ranking of Black hat SEO skills, nothing but two "black chain" and "station group." Today Zhangquan to discuss Black hat SEO

One of the most important things I learned in my creations is to avoid black. Mrs. Z is my childhood art teacher. I already reminded me when I was in school. Later, I heard many similar suggestions at the design institute of Rhode Island, it may be a bit strange at the beginning, but this is a good suggestion. The problem is that we often see dark objects and assume they are black. In fact, in reality, it i

applicationsA binary lookup tree is randomly composed of n nodes, so for some cases, the binary lookup tree will degenerate into a linear chain with n nodes. For example:b figure for a common two-fork search tree, we look at a graph, if our root node selection is the smallest or largest number, then the two-fork search tree is completely degenerate into a linear structure, so, on the basis of binary search tree, there are AVL trees, red and black tre

Insert or delete operations, it is possible to change the balance of the red and black trees, the use of color change and rotation of the two magic can be used to deal with all cases, the unbalanced red and black trees into a balanced red-black tree. In the color change or rotation, often involves three generations of grandchildren: x represents the base node o

Red-black tree is a more data structure used in engineering, its advantage is that the complexity of the search is O (LgN), and the red-black tree will be inserted in the data to maintain a balance, suppress the complexity of the explosion. Although it is not as efficient as Hashtable, it does not have to plan and allocate space beforehand.So how did it do it?Here's what it's all about: 1. Red and

Black-Box Testing (Black-box testing, also known as functional testing or data-driven testing) is the test object as a black box. When using the Black box test method for dynamic testing, it is necessary to test the function of the SOFTWARE product without testing the internal structure and process of the SOFTWARE PROD

We recommend that you first look at the preface: http://www.cnblogs.com/tanky_woo/archive/2011/04/09/2010263.html This chapter has a lot of content, so I will write it in four articles. This article is about some basic concepts and choices. The two articles in the middle are insert and delete, and the last one is a summary. The previous chapter summarizes BST (http://www.wutianqi.com /? P = 2430), BST is relatively small in height and can achieve good performance (because the average time of BS

Because the red-black tree is very interesting to see the kernel, so use the time of the weekend to achieve a play. The operation of the red-black tree is mainly inserted and deleted, and the need to consider more when deleting. The specific operation is not here wordy, Baidu Library has a relatively good article, has said very clearly. Some people may feel that something is not taken into account when loo
