[C++] 우선순위 큐 정렬하기

헤더

#include <queue>

기본

priority_queue<int> pq; //내림차순
priority_queue<int, vector<int>, less<int>> pq; //내림차순
priority_queue<int, vector<int>, greater<int>> pq; //오름차순

커스텀 정렬

#include <queue>

struct compare {
	bool operator()(int a, int b) {
		retuern a > b;
	}
};

priority_queue<int, vector<int>, compare> pq;
