Call once and return twice. The child process PID and 0 are returned respectively in the parent and child processes. Using different return values, you can write different processing bran

Topic Given the head node of a binary tree, it is known that the values of all the nodes are not the same, find the two fork tree with the most nodes in the search, and return the head node of this subtree. For example Max search subtree as right Analytical First of all to explain what is the largest search subtree, is the binary search tree, the value of any node must be greater than the maximum number

How to get the order of the two-fork tree by the pre-sequence and the middle order of the two-fork tree?First of all, we must understand what is pre-order, middle order, sequence.Binary Tree Pre-order: The traversal sequence is, the root node, the Zuozi, the right subtree; middle order: The traversal order is, the Zuozi, the root node, the right sub-tree; Post order: Traversal sequence is, Zuozi, right subt

Java. util. concurrent package source code reading 23 Fork/Join framework Fork tip, forkjoin The previous article has been tracking the pushTask method of ForkJoinWorkerThread, and there is still no way to explain the Fork principle. Let's take a look at the run method of ForkJoinWorkerThread: Public void run () {Throwable exception = null; try {// initialize the

first you have to understand that the project you are importing is likely to be different from your current Eclipse environment,and theJDK version is consistent with the JRE version . , such as those used in the project Tomcat the name is 777 , you have Eclipse there is no 777 of the Tomcat , first make changes to where the environment needs to be changed! and then solve the JSP file is a fork problem, for the JSP file said servlet,jsp , etc. do not k

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

Problem Description: The Web project name in Eclipse has a red fork, but there is no Red Cross for every file underneath. Reason: There's a lot of reasons, and here I only record the reason for my error: Because I used the server in the eclipse's own basic, and then it went wrong. WORKAROUND: Re-new Apache (Tomcat) service, successfully resolved. Operation: Click on the service--> right---> Click new--> click Server--> Choose Apache under your so

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

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-

generate two sub-processes... In fact, the number of processes still increases by the number of algebra. Imagine if a function is executed once, then the process can generate sub-processes, and sub-processes will generate sub-processes ...... In this Recursive Execution, the process expands exponentially. Is this the legendary fork bomb? (how should I write this function? I can see one on the Internet. It'

meet the above requirements: when we find the ownership of the current new node from top to bottom, we will split the full node along the way, then we can guarantee that whenever we want to split aFull node y, make sure its parents are not full. It can be seen that the only way the tree grows tall is to split the root node.First, create a new node Z and then the original y node of t ... 2t-1 (t-1) to the new node Z, and then put the middle keyword in yThe parent node.Insert the keyword into the

problem : Print the binary tree from top to bottom, and the nodes in the same layer are printed to one line from left to right. For example: Print results: 8 6 10 5 7 9 11 Analysis: In order to print each row of the two-fork tree to a single line, we need two variables: One variable represents the number of nodes that have not been printed in the current layer, and the other represents the next level of nodes. Print binary tree void print (binarytre

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-
