TCP文件传输协议的客户端功能实现（JAVA编写）

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.

WINSOCK程序设计共分为客户端和服务器端程序两部分，要求实现功能：服务器端要能监听客户端连接请求，为客户端的连接请求建立SOCKET队列，处理各个客户端发送的数据，并向响应客户端发送应答信息，更新服务器端的端口号。-Winsock program design consists of client and server-side procedures in two parts, requires the function : server can be monitored to client requests for the client to establish a link SOCKET queue handle all the client to send data to respond to a client sent response information update service Works on the port side.
