It took nearly one day to finally implement the dikexch algorithm (Dijkstra. Efficiency needs to be improved, and correctness needs to be verified. Now paste the source code.

least-authorized path is as follows:Traversal gets the actual shortest pathShow Shortest Path:Finally, write an external usage class that you can use on Android or anywhere else.Getdijkstrapath.javaIn the main method, the distance to the target point (5, 4) or (5, 5) is output as follows:The output path is in JSON format and is easy to parse. in Android, the source of the snake is adapted for random generation of related "maps". After various tests, the alg
The margin is for you:A few days ago in the blog Park, a small partner posted Huawei 2010 10K (Salary) Employees 3-level promotion questions.The main problem is the algorithm implementation.in the with a large number of seniors staying in Huawei, as a small partner who loves algorithms , also want to try a little bit of skill. Problem Address: http://www.cnblogs.com/preacher/p/4126261.htmlLet's review the basics before solving the above problems:
The shortest path algorithm of Dijkstra is based on the shortest path of the predecessor vertex, and it is relatively simple in general, the following is the code:
Copy Code code as follows:

First, the prefaceProgrammers in the web and other projects, often need to add files to upload, download, delete the function, sometimes a single file, sometimes multiple file bulk operations, and these features of the code programmers can collect their own as a tool to use, so that programmers in the process of programming will be more than a multiplier, The next blog will explain how to use the file uploa
