第一种格式没有指定排序规则,因此就只能对区域内的元素按数值大小做升序排序。但如果我们是想对一个vector内的string元素按照单词长度进行排序呢?这就需要我们自行指定一个排序规则,例如下面这个例子: //比较函数,按照字符串长度对向量words内的元素进行升序排序 bool is_shorter(const string &s1, const string &s2...

输入:path = "/a/./b/../../c/" 输出:"/c" 提示: 1 <= path.length <= 3000 path 由英文字母,数字,'.','/' 或 '_' 组成。 path 是一个有效的 Unix 风格绝对路径。 这里有一个问题是,如何按照 '/' 来分割路径。C的办法肯定是最高效的,C++有没有什么写起来很快的办法呢?
