Give the coordinates of the n block of ice, the number of penguins on each ice pack and the number of times they can withstand the jump, and ask what ice floe will bring the penguins together.
Analysis:
The limit of the point traffic is converted to the limit of the edge traffic, and the maximum flow is calculated.
Code:
POJ 3498//sep9 #include
The Dinic algorithm, the complexity of On*n*m (n is the number of points, M is the edge count), because the average number of points is less than the amount of edges, so more than Ek (om*m*n) a bit better.

Concept ---- Data Flow Diagram (DFD)
Data Flow Diagram(Date flow divisor, DFD) is a tool used in the SA method to represent the system logic model. It graphically depicts the process of data flow and processing in the system, because it only reflects the logical functions required by the system, it is a function model.
One, Java streaming input/output principle Stream is used to read and write data, Java has a class called file, it encapsulates the filename of the files, just an object in memory, the real file is a piece of space on the hard disk, in this file contains a variety of data, we want to read the data in the file what to do? is to read through a stream, we want to read from the program, for the computer, no matter what type of data is read in 010101101010 such form. How to read the data inside the
