CCCC训练赛一些模板 struct sstream

struct node

friend bool operator< (node n1, node n2)
{
return n1.priority > n2.priority;//"<"为从大到小排列，">"为从小到大排列
}

int priority;
int value;
node(int priority, int value) : priority(priority), value(value) {};

};

priority_queue<node>;

//priority_queue<int, vector<int>,less<int> > qi2;//从小到大的优先级队列，可将greater改为less，即为从大到小

while (getline(cin, line))

stringstream ss(line);
int x;
while(ss >> x)
