Debugging for some peopleCode, And its slow code. After debugging, it is found that this is caused by no initialization. This member has a significant impact on the performance. The performance is 10 thousand times worse than that set or not set.

The classic 8 digital problem mainly uses the "ordered search algorithm" in artificial intelligence, which is also called a algorithm. # Include # include # include # include # include using namespace STD; const int Len = 9; struct pstatus

The first time I encountered the biggest stream problem. Although I know the algorithm of the largest stream, I did not expect to use the largest stream to solve this problem. For the solution, see http://www.cppblog.com/narutoacm/archive/2010/03/01/
