1. Introduction
The red-black tree is a self balanced binary lookup tree. Its statistical performance is better than the balanced binary tree (AVL tree), so the red-black tree is used in many places. In C + + STL, many parts (currently including set, Multiset, map, Multimap) apply the variant of the red-black tree (there are some changes in the

All right, do not square friends, into the subject. We know that the values in HashMap are all key,value, right, in fact, the storage here is very much like the above, the key will be mapped to the address of the data, and the value is in the list with this address as the h
the nature and definition of red-black tree
The Red-black tree (Red-black) is a two-fork lookup tree that satisfies the following properties:
1. Each node is either red or black.
2. The root node is black.
3. All leaf nodes are black (they are actually null pointers, as shown in nil). The leaf node does not contain any
This paper introduces a fast Red Hat Linux installation scheme on the PC platform. It has a high degree of automation-the user can simply start the machine manually and choose to boot from the network to complete the installation process. This can save a lot of time when you need to bulk install a large number of Red Hat Linux systems and require technical staff Red

If you think it is over, it will be wrong, some people told me that there was a red envelope feature. I didn't pay attention to it at first, so I read about it on the merchant's platform, and the payment platform had been there for a long time, after research, we will continue to issue tutori

Among them, Xu Xianxin, Guotao, Li Yang almost all just did 1 years of dad. Earlier, the Xu Xianxin of the first father was embarrassed by the fact tha

Analytical sharing:
The first is the need for personal information. For example, the receipt of red envelopes required to enter the name, mobile phone number, bank card number, etc., this is likely to be fraud;
The second is to shar

To achieve automatic red envelopes, solve the problem has two points:
One: How to monitor the occurrence of red envelopes in real time
Second: How to automatically enter the page when the red envelope arrives and automatically click on the

Red and black TreesThe red-black tree is a two-fork lookup tree , but adds a storage bit to the node's color at each node, either red or black. By limiting the shading of any one path from the root to the leaf,The red and black tree ensures that no path will be twice times longer than the other path , and thus is nearl

In practice, we do not directly use the Binary Search Tree, because the performance of the Binary Search Tree is heavily dependent on the insertion sequence of elements, especially when an element is inserted in an ascending manner, in this case, the binary search tree will become a linked list. In practical applications, we use the "balanced" binary search tree, including the AVL, red, black, and AA trees, the most commonly used is the
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
