Place a small card on a large card, find the minimum moving distance and all possibilities of DFS traversal, and carry out a two-layer for loop between each card and the card to be moved, note that the Backtracking condition meets the immediate break code (for algorithm reference)# Include HDU 1584 spider card

This article mainly introduces how to determine the black hat jump code (js version and php version) of the spider code based on the user-agent ), if you need a friend, you can refer to the black hat seo technique and use it to determine the user-agent of the client browser on the server and perform further operations, Someone has been using this code on the Internet for a long time. first, a js code is used to determine the visitor's path. if it is

Regular expression, Regular expression: the need to find strings that meet certain rules of responsibility. It's really a tool for describing these rules.1. \b is a meta-character used to match a position that represents the beginning or end of a word, the boundary of a word. such as \bhi\b will find all the words of ' hi ' in the article;2. What you're looking for is hi. Follow a Lucy not far behind. At this point, you should use \bhi\b.*\blucy\b . Here * is also a meta-character, refers to the

Determine the jump code (js and php) of the spider Code Black Hat Based on the user-agent, and the user-agentjs One of the techniques used by everyone in the black hat seo method is to judge the user-agent of the client browser on the server side and then perform further operations, Someone has been using this code on the Internet for a long time. First, a js code is used to determine the visitor's path. If it is a search engine, the Code jumps. If it
