Huadian North Wind BlowsKey laboratory of cognitive computing and application, Tianjin UniversityDate: 2015/9/9The red-black tree is a balanced extension of the two-fork tree. The red and black trees adopt an Open data expansion strategy, and for example, insert, query, delete Θ( Lg n) Time complexity, so it is also a more widely used data structure.One, the red

Recently, I was designing a Data Structure course and chose the most difficult development of black and white games, because I had decided to use pure C for development. So before that, my friends said that using MFC for development would definitely not do it. There are a lot of black and white game source code on the Internet, but most of the C language source code is not called graphic library development

"The nature of the red-black tree"The red-black tree is a special two-fork search tree, with all the null pointers of the red and black trees replaced with the external node Nullnode (nullnode->rchild=nullnode->rchild=nullnode). The red-black tree has the following properties: The root node is

Why did Linux use the AVL tree earlier and then prefer the red-black tree?In fact, this is the result of the pragmatism of the red and black tree, and this essay remains a metaphysical point of view. Red and black trees can be exported directly from 2-3 trees, we can no longer mention the red and black trees, but only

But can you be sure that the effect of the grayscale image is the best? The following tips for working with grayscale images in Photoshop will help you

Binary search Tree (i) Concept A binary search tree is a node-ordered two-fork tree, (1) The value of the left branch node of the root node is small. (2) The right branch node value is greater than the root node value (3) All sub-trees are also two-fork search tree Self-balancing binary search tree Balanced binary tree: a two-fork search tree with a depth difference of not more than 1 for all leaf nodes Self-balancing binary search tree: Refers to a two-fork search tree whose operations are

The red-black tree is Another variant of the AVL tree, and he can also maintain a sense of balance in the process of dynamic change, and the worst case scenario for a red-black tree is only the complexity of $o\left (\log n \right) $ , and below we will see that For insertion we have another implementation method that is easier than the AVL tree, not recursive. before we talk about technical details , we

Black box Test (i)1.1 What is a black box testBlack box testing is also called functional testing (functional testing), because in black-box testing, the main focus is on the functionality of the software being tested, not the internal logic. Black-Box testing is a test concept that is very different from white-box tes
