编制程序，监控网络，捕获一段时间内网络上的IP数据包，按IP数据包的源地址统计出该源地址在该时间段内发出的IP包的个数，将其写入日志文件中或用图形表示出来（建议用图形表示出统计结果）。(Program monitoring network, a period of time to capture IP data packets on the network, according to the source address of the IP packet statistics of the number of the source address is issued in the time of the IP package, written into the log file or graph out (that show the statistical results with graphics).)

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.
