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 for a pair of ints: priority_queue<pair<int, int>, vector<pair<int, in...
priority_queue<int> q;//这里用优先队列存储intn; cin >> n;intm = n * (n -1) /2;for(inti =1; i <= m; i++) {intx; cin >> x; q.push(-x);//从小到大升序,因为优先队列默认是大根堆,也就是从大到小排序,取-就从小到大了}vector<int>ans(n+1);for(inti = n -1;i>=1;...
