Balanced binary sorting treeBalanced binary sorting tree (Balanced binary sort trees), previous blog "Data structure" binary sort tree BST spoke BST, and at the end we said that the operation on BST would not exceed O (h), since tree height is so important, So Bbst's study is to make the depth of the
The last time, the content of the nonlinear logical data structure tree is opened, and the deep review and summary of the two-fork tree is started. First, let's review a few important concepts:First, review1. Full two fork tree with complete binary treeA two-prong tree means
noun explanation
Tree this data structure uses the concept of recursion: tree trees or trees;
Degree: The number of sub-trees of the node;
The degree of the tree: the maximum value of the degree of any node in the tree;
Brother: The parent of the two node is the same;

recently searched nodes in the most easily searchable root node. In many application environments, such as Web applications, some fixed content is repeatedly accessed (such as the MV of Jiangnan style). Stretching the tree allows this repetitive search to be done with high efficiency.3.

The definition of a tree
Tree-shaped structure is a kind of important nonlinear structure. A tree structure is a structure with a branch and a hierarchical relationship between nodes.
called the child of the node, and correspondingly, the node is called the child's parents.
The children of the same parents are called brothers.
The ancestor of the node is all nodes from the root to the branch of the node.
Any node in a subtree rooted in a node is called the descendant of the node.
The level of the node is defined from the root, the root is the first layer, and the child of the root is the second layer. Their parents are cousins to each other at the same level of n

The 2-3 trees in the balance lookup tree are explained earlier and the red and black trees are implemented. 2-3 tree species, a node has a maximum of 2 keys, while the red-black tree uses a staining method to identify the two keys.Wikipedia defines B-trees as "in computer science, B-Tree (B-
(d>1). In addition to level D, the number of nodes in each of the other layers has reached the maximum, and all the nodes in level d are continuously arranged from left to right, so the two-fork tree is called a complete binary tree, in which the two-tree is defined as a complete binary tree with all leaf nodes at the

1. Tree Definition
Tree structure is an important non-linear structure. A tree structure is a structure with branches and hierarchical relationships between nodes. It is very similar to
lists: pointers to precursors and successors are called clues, plus the two-linked list of clues is called the clue chain list. The corresponding two-fork tree is called the Clue two fork tree.Thread: The process of traversing a two-fork tree in some order to turn it into a clue two fork tree.1typedefenum{Link,thread} Pointertag;/*link ==0 Indicates a pointer to
1. Overview
Binary lookup trees (Binary search tree, also known as the binary sort tree, that is, Binary kind trees) can support a variety of dynamic set operations, which can be used to express ordered sets, indexing, etc., so in practical applications, binary sorting tree is a very important data structure.
