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

The conversion flow is mainly two inputstreamreader and OutputStreamWriter1. InputStreamReader is mainly to convert the input stream of the byte stream into the character input flow2. OutputStreamWriter is mainly to convert the output stream of the byte stream into a character output flowThe print

First knowledge of reactive StreamReactive stream (response flow/reaction flow) is a set of standards introduced by JDK9 and is a set of data processing specifications based on the publish/subscribe pattern. The response stream began in 2013 as an initiative to provide an asynchronous stream processing standard for non-blocking back pressure. It is designed to so

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

1. Introduction of NiO (New io stream)JDK4 appears nio. The new IO and the traditional IO have the same purpose, are used for the input and output, but the new IO uses a different way to handle the input and output, in a memory-mapped file, the file or a section of the file map into memory, you can access the same memory as a visiting file, This is much more efficient than the old Io, but there are a lot of places where we see the old IO reference, so
