C++ Priority Queue 是一种常用的数据结构,用于解决优先级队列问题。而 Custom Comparator 则是一种高级的数据结构,允许用户自定义比较器,使得 Priority Queue 可以更加灵活地支持不同的优先级排序需求。在这篇文章中,我们将对 C++ Priority Quee 的 Custom Comparator 进行简要解读与分析。 首先,让我们来看一下 Prio...
I am having problem writing a custom comparator for priority queue in C++. The elements' type in the queue ispair<long long,pair<long long, long long>>I want the queue to rank the elements with the smallestfirstelement first, and if there is a tie, rank the elements with the smallests...

priority_queue、map、set这些元素有序的容器都可以自定义比较规则,常用的有以下两种途径: 自定义比较器类(Comparator Class) 重载运算符(缺省比较器类) 自定义比较器类# 在cppreference页面可以看到,这类元素有序的容器都有个默认的Compare比较器类。比如priority_queue的声明: ...
