優先隊列之簡單元素
大頂堆 priority_queue<int> q;
小頂堆 priority_queue<int, vector<int>, greater<int> >q;
優先隊列之結構體
按某一元素的值建大頂堆
struct node{ int a; int b;};bool Operator < (node x,node y){ return x.a < y.a;}priority_queue<node> q;按某一元素的值建小頂堆
struct node{ int a; int b;};bool operator < (node x,node y){ return x.a > y.a;}priority_queue<node> q;新聞熱點
