In the CSDN Community Support Section, I often see people asking why credits cannot be downloaded, and such problems emerge one after another. The points system descriptions on the Forum are scattered and difficult to find, in order to help new registered users quickly learn about the points rules of the forum, and to reduce repeated replies from Community Support Team administrators, the Administrator has

As SEO practitioners, if you do not know the ranking mechanism of some search engines, want to get a good ranking is also a certain degree of difficulty, understand the search engine ranking mechanism can better work for us, so that we better understand the ranking mechanism algorithm. As illustrated below. SEO Elements of the periodic table, is published very early. It was intended to be further explained in this regard, but because of the reasons for the work. The delay did not write out, toda

Test instructions: Given the points on the N two-dimensional plane, find a line that makes the line pass through the most points and finds out the number of points.My thoughts are:Fix two points as a straight line, and then traverse the other points to see if the line is on the other side and the record is traversed al

First of all we want to know is that Baidu Library points and Baidu know is the same system, you know in Baidu to obtain points can also be used for Baidu Library. The 2nd is that integrals are made up of empirical values and wealth values, and you can buy documents in a library using the wealth value you know. Then we will be divided into two aspects to understand how Baidu's library

Purpose: Crawl all secondary data in the Kunming range, including name, coordinates.First into the basic, this article mainly on the principle, and the realization of step decomposition, for the Python code to lay the groundwork for writing.Since it is the foundation of the 0, it will be more detailed.As the realization of the purpose, crawling all the data of Kunming City, is to obtain the Baidu map on the Kunming range of all key words with secondary school Geographic information data (

Label: style blog HTTP color Io OS ar Java sp I. Application Scenario: the map application determines whether a location is in a region. I used Baidu map and implemented the code as Js. As far as I know, Baidu map API already provides this function. Ii. Overview: 1. the boundary of the administrative area is a polygon. 2. polygon is divided into Convex Polygon and concave polygon. 3. Application: generate random data (that is, a plane coordinate) within the boundary of an administrative division

need to master, beginners Java, the first is certainly taught you how to execute Java programs on the command line, but many people once the Java finished, the IDE used, forget this. Why emphasize to know this, know the Java most pure startup way, you can start when the problem, to analyze how many directories started, how to execute naming, parameters, whether there are missing. This will help you to really develop and solve the strange and environment-related problems. The knowledge that nee

Given n points on a 2D plane, find the maximum number of points that lie on the same straight line.There are 3 special cases to consider: 1, x1=x2, slope infinity, 2, X1=x2,y1=y2, the same point also to be counted, when the final result is calculated to add the value, and the same point number is initialized to 1, that is, its own; 3, y1=y2;When calculating the slope (double) (

Baidu Browser How to get points: 1, only need to login Baidu browser, daily search and access to the Web page will generate points, these points accounting into your Baidu browser when the use of Baidu account, the highest daily access to 320 points. 2, a Beijing-east red envelopes as long as 10
