单射函数问题 设函数f将点集S = {0,1, , n -1}映射为f (S) = { f (i) | iÎ S} Í S 。单射函数问题要 从S中选取最大子集X Í S 使f (X )是单射函数。 例如，当n=7， f (S) = {1,0,0,2,2,3,6} Í S 时， X = {0,1,6} Í S 是所求的最大子集。-Injective function, the function f the problem will be the point set based S = (0,1,  , n-1) maps to f (S) = (f (i) | iÎ S) Í S. Injective function of the problem from the largest subset of S, select the X Í S so that f (X) is injective function. For example, when n = 7, f (S) = (1,0,0,2,2,3,6) Í S, when, X = (0,1,6) Í S is a subset of the desired maximum.

模拟数据链路层的实现 采用 go back n 的方案，进行差错控制 vc6.0-implement the data link protocol of "go back n"

使用方法： 首先安装winpacp驱动，发送的时候可以选择ARP的TYPE。如果是ARP请求报文，则只要输入要问的IP地址，如果是ARP应答报文则要输入发送端的IP以及对方询问MAC地址对应的IP地址。 最后的发送速度可选参数为：（大小写敏感） fast----------最快 hear---------每60MS一个包（比较适合结合SNIFFER做监听） slowhear---每500MS一个包 auto---------每1秒一个包 slow---------每2秒个包 -Usage: First, install the driver winpacp, send when ARP can choose the TYPE. If the ARP request message, the question as long as the input to the IP address, if the ARP response packet will have to enter the sending end of the IP and MAC address of the other asked whether the corresponding IP address. The final optional parameter for sending speed: (case sensitive) fast fastest hear- a packet every 60ms (SNIFFER make more suitable combination of monitor) slowhear- every 500ms a packet auto- every one seconds a packet slow- every two seconds of packet
