例如,当我们使用标准库容器如std::vector、std::string等时,如果需要将一个容器的内容转移到另一个容器中,可以使用移动语义来避免不必要的复制操作。这可以显著提高 阅读全文 posted @ 2024-09-17 16:38 daligh 阅读(19) 评论(0) 推荐(0) 编辑

优先队列的声明可以采用形式:priority_queue< int, vector<int>, greater<int> >myQueue; 由于题目明确指出队伍号之间有空格,最后一名后面没有空格。因此在输出前需要判断当前队伍是否为最后一只队伍。可以用int ans变量保存已经输出的队伍的个数,当ans==n时说明此时为最后一只队伍,不输出空格而是输出换行\n。 同样...
