<section id="description"><p> Comma quibbling是Eric Lippert在他的<a href="http://blogs.msdn.com/b/ericlippert/archive/2009/04/15/comma-quibbling.aspx" title="链接:http://blogs.msdn.com/b/ericlippert/archive/2009/04/15/comma-quibbling.aspx">博客中</a>最初设定的任务。 </p>任务: <p>编写一个函数来生成一个字符串输出,它是列表/序列中输入字的串联,其中: </p>没有单词的输入产生仅两个大括号字符“{}”的输出字符串。只有一个单词的输入,例如[“ABC”],会在两个大括号内产生单词的输出字符串,例如“{ABC}”。两个单词的输入,例如[“ABC”,“DEF”],产生两个大括号内的两个单词的输出字符串,其中单词由字符串“和”分隔,例如“{ABC和DEF}”。三个或更多单词的输入,例如[“ABC”,“DEF”,“G”,“H”],产生除了最后一个单词之外的所有输出字符串,用“,”分隔,最后一个单词用“和”分隔。 “并且都在括号内;例如“{ABC,DEF,G和H}”。 <p>在此页面上显示输出的以下一系列输入测试您的功能: </p> []#(无输入字)。 [“ABC”] [“ABC”,“DEF”] [“ABC”,“DEF”,“G”,“H”] <p>注意:假设此单词是此任务的非空字符串大写字符。 </p></section>
