The first question directly runs the maximum flow can. The plan is built according to the cost flow, the cost is 0.For the second question, in the first question Dinic the remainder of the network to build, the original image of each side (I,J), built (I,J,INF,CIJ), that the cost of C can be augmented by the road. Then from the new source point, the s,1,k,0 represents the traffic to increase the K. Run the minimum cost maximum flow.#include #include #include #include using namespaceStdConst intn

This example describes the go language compression and decompression tar.gz file. Share to everyone for your reference. The specific analysis is as follows:
Golang processing compression package, the most commonly used is the tar.gz, here wrote a test.
Compressed files:
Copy Code code as follows:
Package Main
Import (
"FMT"
"OS"
"IO"
"Archive/tar"
"Compress/gzip"
)
Func Main () {

FW, ERR: = OS. Create ("tar/lin_golang_src.tar.gz")
If Err!= nil {

natural logarithm of x.
sqrt (x)
Returns the X square root.
int (x)
Returns the value of the truncation of X to an integer.
RAND ()
Returns any number n, where 0
Srand ([Expr])
Set the seed value of the RAND function to the value of the expr parameter, or use the time of day if you omit the Expr argument. Returns the previous seed value.
An example is provided:
[Chengmo@centos5 ~]$ awk ' begin{ofmt= "%.3f"; fs=sin (1); F
The language file system is called a stream file (stream), text stream (body file), binary stream (binary file) buffer and non-buffered file sequence operation file and random operation file sequence file: Read/write the K block before reading/writing the 1th to K-1 data blocks; random file: Direct read/ Write the k block; the action of the body file is usually the sequential file; the binary files are all random files.

using a rigorous test-driven development approach, we can first create a test instance and then implement the code to match the test instance. In practice, the exact order may vary depending on the code to be tested.The starting test scenario looks like this:
public void Testsearchbycountry () {Setrequestpathinfo ("/search.do");Addrequestparameter ("Country", "FR");Actionperform ();}
Here, we establish the path to invoke (Setrequestpathinfo ()) and a
logarithm of x.
sqrt (x)
Returns the square root of x.
int (x)
Returns the truncated value of x to an integer.
RAND ()
Returns any number n, where 0
Srand ([Expr])
Set the seed value of the RAND function to the value of the expr parameter, or use the time of day if the expr parameter is omitted. Returns the previous seed value.
To illustrate:
[Chengmo@centos5 ~]$ awk ' begin{ofmt= '%.3f '; fs=sin (1); Fe=exp (Fl=log) fi=
The word "filter" is confusing. a subnode, two subnodes, and three subnodes can be mounted at the next level .... Filter the meanings of a sub-node, such as scanning the entire table.

After saving the view, refresh the cache and you can see the drop-down box for language selection on the foreground. Then we can try to select
