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 red/

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 red-

The red-black tree is a balanced binary tree, but it is not a perfect balanced binary tree.Although we hope that all searches can be found in ~ The lgN comparison ends, but it is too costly to maintain a perfect balance between the trees during dynamic insertion. Therefore, let's just relax and look at the limitations, we hope to find a
I. OverviewRed-black tree is a classic storage structure, in itself is a binary search tree, just on this basis, the tree node added a property to represent the color (red or black). By restricting the coloring of nodes from the root node to the individual paths of the leaves, it is ensured that no path will exceed twice times the length of the other path, so that the red-
Red and black Trees (red-black tree)
The red-black tree is a type of BST, but a storage bit on each node indicates the color of the node (R or B); The red-black tree ensures that the difference of all paths is not more than one-fold on any path from root to leaf, resulting in a nearly balanced BST;
Each no
It's still the same, first of all:
Property 1. nodes are red or black
Nature 2. The root is black
Nature 3. All leaves are black (leaves are nil nodes)
Nature 4. If a node is red, its two sons are black
5. All simple paths from any node to its leaves contain the same number of bla

The red and black trees (red-black tree) are one of many balanced search trees, so the time complexity of basic operations (query, delete, search) and so on in the worst case is O (LGN).13.1 The nature of red and black treesThe red and black tree is a binary search tree, and an attribute is added to each node to indica
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.

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

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
A red-black tree is a two-prong search tree with color attributes for each node, with a color of red or black. In addition to the general requirements of the binary search tree, we have added the following additional requirements for any valid red-black tree:Nature 1. The nodes are red or black.Nature 2. The root is black.Nature 3. All leaves are
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
