列举制定的目录中被打开的文件，和打开这些文件的进程的PID，命令：lof 驱动文件 目标文件夹。由于驱动的限制，该程序仅适用Windows 2000/XP。(Listed in the directory has been developed to open the file, and open the files of the process PID, the command: lof driver file destination folder. As the driving restrictions, the program applies only to Windows 2000/XP.)

无线传感器网络中使用kmeans算法对网络节点进行分簇(wsn kmeans)

zoj094 Matrix multiplication problem is a typical example of dynamical programming. Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose. For example, let A be a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix. There are two different strategies to compute A*B*C, namely (A*B)*C and A*(B*C). The first one takes 15000 elementary multiplications, but the second one only 3500. Your job is to write a program that determines the number of elementary multiplications needed for a given evaluation strategy.
