The basic structure of the following cocos2d-x and some important classes are introduced in the previous article, "Rookie learning Cocos2d-x 3.x--basic Concept", and here we begin to introduce and analyze these important classes separately. Start it ~ ~ ~
Node Nodes class
The node class is a very important class in Cocos2d-x, it inherits from class ref, about the ref class, the ref class is a memory managed
Cocos2d-x uses the scene, layer, Genie hierarchy to organize the game elements, at the same time, this hierarchy also corresponds to the rendering level of the game, so the game elements can be organized into a tree structure, it is called a rendering tree.
The Cocos2d-x abstracts every game element on the rendering tree into a Node, that is, a Node. All game elements are inherited from Node, so they all have the features provided by Node.
Node defines the general features of a plotting object,
First, let's take a look at the msdn example.Program: Print the names of all nodes in a tree.

This article mainly introduces the basic tutorials for JavaScript operations on HTMLDOM nodes, including operations such as creating, modifying, and deleting nodes. It also mentions appendChild () and insertBefore () when inserting a node, you need to pay attention to this issue. For more information, see the DOM. This allows you to use JavaScript to obtain, create, modify, or delete a node.

LeetCode -- Reverse Nodes in k-GroupDescription:Given a linked list, reverse the nodes of a linked list k at a time and return its modified list.If the number of nodes is not a multiple of k then left-out nodes in the end shoshould remain as it is.You may not alter the values in the
For example, a UL has 10 Li, and the 3rd Li has a special style (such as red color, the other is black). I want all other li--not including red li--color also set to red, at this time, you need to get red Li's all sibling nodes.
Brother, is peace with you, neither at the level nor the next level, and there may be older than you (brother), may be younger than you (younger brother). Sibling node in the same way, here is a regular method of acquiring si
In the actual development, we often want to get an HTML element in the page, dynamically update the element's style, content attributes, and so on.
So how do you get the elements to be updated? There are many ways to get these nodes with JavaScript, and here are some of the methods that are summarized.
1. Obtain from document node:
(1) document.getElementById (ElementID): This method through the node ID, can accurately obtain the required elements,

JQuery uses control nodes to transmit parameters only through the get method at the front end. jqueryget
This example describes how jQuery uses control nodes to pass parameters only in the foreground using the get method. Share it with you for your reference. The specific analysis is as follows:
This is also the content of html dom. The core of Front-End scripting languages such as javascript and jquery is
The maximum distance between nodes in a binary tree (the longest path of the tree)-recursive method, the maximum distance of a binary tree
In the previous article, we described a kind of deformation of this question and provided a non-recursive solution.
Now I will giveOriginal questionARecursive Solution. As you can see, the Code Implementation of the recursive solution provided in the previous blog is quite concise.

Question: Given a binary tree, the distance between nodes is the number of nodes contained in the path between two nodes, and the maximum distance between nodes is obtained.

Filter nodes inaccessible to Hadoop using Shell scripts
The hp1 cluster recently used, because the maintenance staff of the cluster is not powerful, the node will always drop one or two after a while. Today, we found that HDFS is in protection mode when Hadoop is restarted.
I decided to filter out all the inaccessible nodes in the slaves node, so I wrote a small script and recorded it here for convenience
Title link, Password: HPUDescriptionGiven a tree (a connected graph with no cycles), you have to find the farthest nodes in the tree. The edges of the tree is weighted and undirected. That's means you had to find nodes in the whose distance was maximum amongst all nodes.InputInput starts with an integer T (≤10), denoting the number of test cases.Each case starts with a integer n (2≤n≤30000) denoting the tot

Try to write an algorithm to exchange the left and right subtree of all nodes in the two-fork tree
Algorithmic thinking
Because it is necessary to exchange the left and right subtrees of all the nodes in the two-fork tree, the simplest way is to use recursion. To complete the whole tree of the exchange of trees, you can consider two ways, from the top down to excha
