The Dijkstra algorithm is a familiar one in the shortest path algorithm, and is a single-origin full-path algorithm. This algorithm is known as a successful model of "greedy algorithm".
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 genera
