First, the order of the tree -two-fork tree-two fork to find the tree is explained more clearly. One, the tree A tree is a finite set of n (n≥0) nodes. In any of a non-empty tree: (1) Having and having only a specific node called root; (2) When n>1, the remaining nodes can be divided into m (m>0) disjoint finite set T1,T2,...,TM, in which each set itself is a tree and is called the root subtree (subtree). t

The Balanced binary tree (balanced Binary) is an evolutionary body of two-fork lookup trees and the first two-fork tree to introduce the concept of equilibrium. In the 1962, G.M Adelson-velsky and E.M Landis invented the tree, so it was called an AVL tree. Balanced binary tree requirements for each node, its left and right subtree of the height of the difference can not exceed 1, if the insertion or deletio

Pre-order A quadtree or four-dollar Tree is also called the Q-tree (Q-tree). Four fork tree is widely used in image processing, spatial data index, fast collision detection in 2D, storage sparse data, and eight-fork tree (octree) is mainly applied to 3D graphics processing. This can be useful for programming games. This paper focuses on the introduction of the principle and structure of quadtree and eight-

So the last line of code is the backtracking process. If the buffer parameter is not a reference, then backtracking is not required.The understanding of backtracking can be deepened in both ways. Obviously the above one is much more efficient than the code below, but there is no need to tak

On the principle of binary search tree on-line resources are quite many, and the situation is a little complicated, so here I will no longer state, directly on the code bar: #bst. php Files debugging when you can call the sequence traversal to do, I in the previous blog provides PHP implementation of the two-tree graphics, with visual help can better help us to debug, detailed everyone can visit my previous blog: "Using PHP to achieve two-tree graphics display" The above is the PHP two

Title: Enter a binary tree to find the depth of the tree. The length of the longest path is the depth of the tree, which is a path of the tree from the root node to the node of the leaf node (including root and leaf node). Idea: the so-called depth refers to the length of the longest path from the root node to the leaf node, that is, the number of nodes on the path. To analyze the problem, enter root node root and ask its depth to find the depth of the root left and right subtree first, take its

We can use a lot of ways to traverse a binary tree, such as first-order traversal, in-sequence traversal, after the next traversal, in fact, are implemented by recursion. Today we have a sequence traversal of the two-fork tree, which requires the use of another data structure-the queue. The sample code for this article is uploaded to Https://github.com/chenyufeng1991/LevelOrderBinaryTree. The basic idea of sequence traversal is that when accessing a

Last time we looked together. The sparse matrix compression storage and the implementation of some basic operations of matrix based on ternary table storage structure. This time, let's take a look at the tree. The most important data structure-the implementation of the two-fork list storage structure of the two-fork tree and the implementation of four traversal operations of the two-

first, the Clue two fork tree principle Introduction to the principle of binary tree and special binary tree The article mentions that binary trees can use two kinds of storage structure: sequential storage and two-fork list. In the process of using the two-fork-list storage structure, there will be a large number of NULL pointer fields, in order to make full us

Two fork Sorting tree introduction We know that the binary tree, each node has a maximum of 2 Shang trees, known as the Saozi right subtree.The binary sort tree, apparently also a binary tree, has a more salient feature that renders sorting on the data field .In the two-fork sort tree , the data field of the left subtree of each tree is less than its root node value, and the data field of the right subtree
