If we pass a query `language` while requesting index page, we will get the wrong header `Content-Language`. Please see the result below:

重构 KeyComparator 并通过更多的测试用例来确保排序功能的正确性
同时修复了可能存在溢出导致比较结果不正确的问题，目前：
1. 字符串长度比较：在 compareStrings 方法中，字符串的长度比较使用 Integer.compare，这部分代码不会产生整数溢出问题。
2. 数字部分的比较：在 compareNumbers 方法中，数字的比较是基于字符比较的（即逐位比较每个数字字符），没有涉及到将数3. 字字符串转化为 int 或 long 类型的操作，所以不会存在整数溢出问题。
4. 处理小数部分的比较：在 compareDecimalNumbers 方法中，类似地，比较操作也是基于字符的，不涉及到数值转换，因此也不存在整数溢出问题
