Single-Column mode commonly used in JAVA and android, single-column mode in JAVA and android In many development projects, in order to save resources, the constructor of a class is privatized, so that multiple instances cannot be created in the entire project. This method is called the singleton mode. The following Code introduces the singleton mode: After creating a java project, create an entity class Use

There are three shortest path algorithms in this chapter: 1, Bellman-ford algorithm: To solve the general situation of the single source shortest path problem, can be applied to the edge of the weight is negative, and there is a loop, the algorithm returns a bool value, indicating whether there is a source node can be reached from the weight of a negative loop. If present, returns false, otherwise, you can find the shortest path and the weight of this
