说明：  在Internet上的聊天室程序一般都是以服务器提供服务端连接响应，使用者通过客户端程序登录到服务器，就可以与登录在同一服务器上的用户交谈，这是一个面向连接的通信过程。因此，程序要在TCP/IP环境下，实现服务器端和客户端两部分程序。(In Internet chat rooms on the procedure is generally based on the server side connection in response to the provision of services, the user through the client program to log on to the server, you can log in the same server with the user to chat, this is a connection-oriented communication process. Therefore, procedures to TCP/IP environment, the realization of server-side and client procedures in two parts.)

在给定字符串中找出单词（ “单词”由小写字母字符大写字母和构成，其他非字母字符视为单词的间隔， 如、问空格号、数字等等；另外单个字母不算单词）；找到单词后，按照长度进行降序排序， （排序时如果长度相同，则按出现的顺序进行排列），然后输出到一个新的字符串中；如果某个单词重复出现多次， 则只输出一次；如果整个输入的字符串中没有找到单词，请输出空串。输出的单词之间使用一个“空格”隔开， 最后一个单词后不加空格。(Identify the word (" word" character from the uppercase and lowercase letters constituted, other non-alphabetic characters as word spacing, such as asking a space number, number, etc. another is not a single letter word) in a given string find words after descending order according to length, (if the same length, the order stated that appears when sorting arranged), and then output to a new string If a word is repeated several times, only output once If the entire input string is not found in word, outputs an empty string. Used between the output of a word " space" separated, no spaces after the last word.)
