I've seen people using negative edges when creating a priority queue because writing a minimum is simply too tedious. And, I gotta say, I agree with them! Look at this code when you have to declare a min heap fo
1、优先队列的创建与其他容器一样，优先队列的创建就是固定的那句代码“容器名<类型名> 变量名”：priority_queue<T> pq; //T为数据类型或类名优先队列可以基于现有的vector数组来初始化，但是无法被直接赋值：vector<int> v={1,2,3,4,5};priority_queue<int> pq(v.begin(),v.end());为了实现自定义...

另一种处理方法是利用STL的优先队列,priority_queue,非常方便简单高效,虽然priority_queue的基本理论思想还是上述的优化思想,但是STL可以直接用相关的功能函数实现这些操作,相对简单,详细参见我的程序。 注意priority_queue与qsort的比较规则的返回值的意义刚好相反 ...
