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.

TCP的客户服务器通信程序 一：程序运行过程 1、运行服务器程序，等待客户端发出请求 2、运行客户端程序，输入客户的IP地址，请求连接 3、若连接成功，服务器端显示客户的IP地址及端口号；客户端接收文件并保存在d:clientls.txt下，否则，显示错误信息。 二：程序实现原理 发送端：打开文件，逐一读取字符到缓冲区（缓冲区大小为1024），若文件大于1024，则成块发送；若小于，则直接发送。 接受端：与发送端同理。-TCP client-server communication program one : running a process, running the server and wait for the client to issue two requests, the client operating procedures, the importation of customer IP address, link request, if successful connection, the server-client shows the IP address and port number ; the client receives the document and preserve d : client ls.txt, otherwise an error message. 2 : Principle procedures transmitter : open the file, read each character to the buffer (buffer size for 1024), and if the document is greater than 1,024, then sent into pieces; If less, then sent directly. Receivers : Send-the same reason.
