To delete some edges so that the start point and the end point are not connected, the number of edges to be deleted should be as few as possible when the sum of the right values of the deleted edges is the smallest.

Problem-solving report question Portal question: Give an undirected graph, as well as the start and end points. To delete some edges so that the start point and the end point are not connected, the number of edges to be deleted should be as few as possible when the sum of the right values of the deleted edges is the smallest. Obtain a ratio: the weight of the number of remaining edges and the number of deleted edges. Train of Thought: Obviously, a minimum cut is a minimum cut if the starting poi

Java learning notes 43 (brief introduction to the print stream and IO stream tools) and learning notes Print stream: There are two classes: PrintStream and PrintWriter. The methods of the two classes are the same. The difference is that the constructor PrintStream: constructor: receives the File type, receives the string File name, and receives the byte output

One, file input stream and file output stream: Fileinputstream,fileoutputstreamFileInputStream can use the Read () method to read one byte at a time and return it as an int, or to read into a byte array when using the Read () method, the number of elements of a byte array, and how many bytes are enrolled in. In the process of completing or writing the entire file, such a byte array is usually used as a buff

Stream is one of the most overlooked function series in PHP development (SPL series, stream series, pack function, encapsulation protocol), but it is a useful and important function. Stream can be translated as "stream", in Java, flow is a very important concept. Three Kingdoms Live CasinoThe concept of

This kind of driver mainly presents streaming function interfaces, including XXX_Init, XXX_Deinit, XXX_Open, XXX_Close, XXX_Read, XXX_Write, XXX_Seek, XXX_IOControl, XXX_PowerUp, XXX_PowerDown, etc, note that the preceding interfaces must be output, and XXX must contain three characters. Otherwise, an error occurs. You can manually call the RegisterDevice () and DeregisterDevice () functions to load and uninstall the driver. Users can operate such devices as standard files. They can interact wit

Java IO stream: Random file read/write, javaio stream The Java. io package provides the RandomAccessFile class for creating and accessing random files. Using this class, you can jump to any position of the file to read and write data. The program can insert data into a random file without damaging other data of the file. In addition, the program can also update or delete the previously stored data without o
