Binary tree is a very common and useful data structure, which combines the advantages of an ordered array with a linked list. Finding data in a binary tree is as fast as finding data in an array, and adding and removing data in a binary tree is as efficient as it is in a linked list, so the relevant technology of binar
ajax| Dynamic | tree-structured tree structure is a kind of widely used data structure. The genealogy of Clan and the organization form of modern enterprise in human society are all tree-shaped structure. In the field of computer,
node.Descendants: Conversely, any node in a subtree that is rooted in a node is called a descendant of that node.Level: defined from the root: The root is the first layer and the child of the root is the second layer. Parents on the same level of the knot are cousins.Depth or height of the tree (depth): The maximum level of the nodes in the tree is called the depth or height of the tree.Ordered
1. Preface:The dynamic find tree is mainly: two fork find tree ( Binary Search Tree ), Balanced binary lookup tree ( Balanced Binary Search Tree ), red-black tree (Red-black Tree) , B-
One problem with using a two-fork search tree is that one branch of the tree has many layers, while the other branches have only a few layers, just like this:If the amount of data is large enough, we will consume a significant amount of time when we are doing an additional pruning on an edge. We spend our energies building a structure that can improve efficiency,
A tree is a data structure in which an element can have two or more data elements, with a one-to-many feature that uses a tree structure to store files. the overview of the treeRead
Node Degree: The number of child nodes. For example, there are 3 sub-nodes in Node 1, and the degree of Node 1 is 3.

A Tree is a finite set of n (n ≥ 0) nodes. In any non-empty tree:
(1) There is only one specific Root node;

Why is B + tree used? Simply put, it is because the files are large and cannot be fully stored in the memory. Therefore, it is necessary to store the files to the disk.

Why is B + tree used? The reason is:
1. files are large and cannot be stored in the memory. Therefore, they must be stored on disks.

1. A tree is a finite set of N nodes. If n = 0, it is called an empty tree. In any non-empty
Red-black tree is a relatively common data structure in computer science, which makes the search, insertion and deletion of data can maintain the time complexity of O (LGN). However, compared to the general data structure, the implementation of red-black trees has increased the difficulty. The implementation of the red-black

Two methods of implementing the tree structure 1. Recursive method
Recursion refers to an explicit invocation of itself in a function.
The feature of the tree structure by recursion is that it is faster to write data and slower to display (especially in the case of branches/levels of trees). Applies to the case that th
a non-tree T:(1) There is a special data element called the root node of the tree, and the root node has no precursor nodes.(2) If n>1, the rest of the data elements outside the root node are divided into M (m>0) disjoint sets of T1,t2,...,tm, each of which is a set of Ti (1≤I≤M) itself is a tree. The tree T1,t2,...,t
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
