可以说我有几个短字符串:
string[] shortStrings = new string[] {"xxx","yyy","zzz"};
(这个定义也可以改变数组和字符串的长度,所以不是固定的)
当给定字符串时,我想检查它是否仅与 shortStrings 结合,如何?
假设功能就像bool TestStringFromShortStrings(string s)
然后
TestStringFromShortStrings("xxxyyyzzz") = true;
TestStringFromShortStrings("xxxyyyxxx") = true;
TestStringFromShortStrings("xxxyyy") = true;
TestStringFromShortStrings("xxxxxx") = true;
TestStringFromShortStrings("xxxxx") = false;
TestStringFromShortStrings("xxxXyyyzzz") = false;
TestStringFromShortStrings("xxx2yyyxxx") = false;
请推荐一种记忆力不紧张且速度较快的方法。
[EIDT] 这个函数有什么用?
我个人会用这个函数来测试一个字符串是否是拼音的组合ok,一些中文的东西。如果您看不懂中文,则跟随中文是一回事。
检测一个字符串是否为汉语拼音(例如检测是否拼音域名) 所有的汉语拼音有:</p>

用下面的正则表达式方法,效果轻松了,而且很简单,就是对慢(最擅长的方式)长字符串比较,解决内存溢出</p>
(用正则表达式试了一下:最简单,效果也很好,就是有点慢。长字符串上的递归方式太麻烦了,太容易溢出栈了。)
