真正的仿windows计算器，有连续运算如1+2+3+4,但是不能一直按运算符，可以连续按等于号，如1+2=3再按=就是5再按7-Real imitation windows calculator, there is a continuous operation, such as 1+2+3+4, but not always according to operator, you can continuously by equal numbers, such as 1+2 = 3 then = is a 5 and then 7

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.

类似一个聊天工具，分为服务端和客户端，需要先运行服务端。主要是利用Socket进行数据的异步传输，在局域网内互发消息，同进也实现了一个简单的聊天程序。-Similar to a chat tool, divided into server and client, need to run the server. Socket is mainly carried out using the asynchronous data transmission, each message in the LAN, also achieve the same into a simple chat program.

SockProxy: ============================ 该程序透过服务器sock5代理访问防火墙外的程序，这里通过运行server程序来模拟远端。 不过该实例的运行需要有防火墙支持！-SockProxy : ============================ through the process server sock5 Acting visit outside the firewall procedures here by running server process to simulate the distal . However, the examples of the need for operational support firewall!
