In the last blog, we detailed the tree and two-fork tree data structure and its characteristics, this time, we use C + + to implement the binary tree definition of binary tree node structure

Introduction to Stretching tree
The stretching tree (splay) is a special two-fork lookup tree.Its special meaning is that, in addition to itself is a binary lookup tree, it also has a feature: When a node i
We explained the 2-3 tree in the balance lookup tree and the implementation of the red and black tree. 2-3 tree species, a node has a maximum of 2 keys, while the red-black tree uses the staining method to identify the two key.

Rotate the 90-degree output binary tree counterclockwise (Data Structure Test 2) and the 90-degree Binary Tree
Rotating a 90-degree print binary tree in a counter-clockwise manner is a special medium-order traversal algorithm.

Sub-structure and sub-structure of the tree
1. Question
Enter Two Binary Trees A and B to determine whether B is A sub-structure. The binary tree structure is as follows:
Struct BinaryTreeNode
{
Int m_nValue;
BinaryTreeNode * m_pL
A tree is a finite set of n (n>=0) data elements of the same type. The data element in the tree is called a node. The n=0 tree is called the empty tree, and any non-empty tree T for N>0 is:1. There is only one special node called the root node of the
before we introduce the traversal algorithm of binary tree, we need to introduce the concepts of binary tree and traversal method.
Two fork Tree: is a special structure of the tree, in the binary tree, each node can have a maxim
node can contain up to 2 T-1 keywords, so an internal node can have up to 2 t children. Let's say that a node is full, if it happens to have 2 T-1 keywords.
T = 2, B is the simplest. At this time, each inner node has two, three, or four children, that is, a 2-3-4 tree. However, in practice, a large T is usually used.
Purpose:
Tree B is a multi-channel balanced search
The pre-order traversal order of the binary tree is: root node, left Tree, right tree
The central traversal order is: left Tree, root node, right tree
The descending order of traversal is: left Tree, right
root node's right subtree (left), resulting in the root node's balance factor from-1 to-2 Zuozi
The imbalances that may result from the four situations can be balanced by the rotation. There are two basic types of rotation:
(1) Left rotation: Rotate the root node to (the root node) the left child position of the right child
(2) Right rotation: Rotate the root node to (the root node) the right child's position on the left child
3. The rotation operation of AVL
Binary Tree definition:From the Baidu Encyclopedia. In computer science, a binary tree is a tree structure that has a maximum of two subtrees per node. The subtree is often referred to as the left subtree and the right subtree (subtree). Binary trees are often used to implement a two-fork search
Tree structure is a type of widely used data structure. The Genealogy of clan in human society and the organization form of modern enterprises are tree structures. In the computer field, the file management structure in the file system, the page table in the memory managemen

"left child, that is K1" shaking vigorously. The K1 becomes the root node, K2 becomes the right subtree of K1, and the right subtree of K1 becomes the K2 left subtree.The rotation of the LR?? When LR is out of balance, it takes two rotations to restore the AVL tree to a balanced position. Such as:?? The first rotation is "RR rotation" around "K1", and the second is "ll rotation" around "K3". Copyright NOTICE: This article for Bo Master original artic
