Solution report:
It is still a typical problem of the minimum spanning tree. I used the Kruskal algorithm. Discuss said that the prim algorithm is suitable for dense graphs and the Kruskal algorithm is suitable for sparse graphs. This question is obviously a dense graph, so we should use the prim algorithm for it. However, I still don't use prioriy_queue very much, but I can only use the Kruskal algorithm...

problem?[Email protected][Email protected]Description: System.out.println (per); The ToString method for calling the parent class object by default(2) So, what is the result of the program running? Use Eclipse to open the source code of the println (per) method and see which methods are called in the method, can you explain the results of this example?Returns null if the argument is an empty string, otherwise returns the return value of ToString ().ToString () returns a string that describes th
reconstruct related classes. To make it easy to understand, let's say, for example, the car Class (cars), suppose there are 2 subcategories, Truck Class (Truck) and bus Class (bus), they have [set engine] This action behavior, through the different engine specification settings, you can set them to such as 1500cc (Car1500) , and 2000cc (Car2000) of the car.So, whether it's a 1500cc truck or a 2000cc truck, or a 1500cc bus or a 2000cc bus, they can be subcategories of cars, and:-There is a sub-c

Simple Factory, factory method, abstract factory all belong to the creation pattern in design pattern. Its main function is to help us extract the instantiation part of the object, optimize the architecture of the system, and enhance the extensibility of the system.
This article is my understanding of these three patterns after learning a summary and the difference between them.

At present, machine learning is one of the hottest technologies in the industry.With the rapid development of computer and network, machine learning plays a more and more important role in our life and work, and it is changing our life and work. From the daily use of the camera, daily use of the search engine, online every time shopping, to driverless cars, smart homes, intelligent robots, etc., have machine learning shadow.facebook Open source AI sys
