优先队列的应用 好坑,好坑,好坑,重要的事情说三遍! #include<iostream> #include<cstdio> #include<cstring> #include<queue> using namespace std; #define maxn 50005 struct Node { int f,s,id; friend bool operator < (Node a,Node b) { if(a.f != b.f) return a.…

题目链接:http://acm.hust.edu.cn/vjudge/contest/view.action?cid=115361#problem/D 题意大致是:给出最多50000个人,拥有最初速度F和1秒后的速度V,(F<=500,V<=100)每秒将速度最快的那个人淘汰,按淘汰的人的顺序输出他们的序号. 思路:由于人数很多,用暴力更新每秒淘汰的人显然会TLE.注意到F很小,那么对于任意两个人来说,即使有500的路程差,速度快的那个人哪怕是每秒只快1米,在501秒后就能超越,也就是说,50…

STL 中优先队列的使用方法(priority_queu) 基本操作: empty() 如果队列为空返回真 pop() 删除对顶元素 push() 加入一个元素 size() 返回优先队列中拥有的元素个数 top() 返回优先队列对顶元素 在默认的优先队列中,优先级高的先出队.在默认的int型中先出队的为较大的数. 使用方法: 头文件: #include <queue> 声明方式: 1.普通方法: priority_queue<int>q; //通过操作,按照元素从大到小的顺序出队…

用优先队列储存每个人的初始距离和编号,每轮求出最快的人,然后pop掉 一开始想遍历队列的,后来发现队列没办法遍历,汗-_-! 题意,给几个第一秒冲出的距离和以后速度,求每秒后最前面人的编号,求完后最前面的退出 2 3 100 1 100 2 3 100 5 1 1 2 2 3 3 4 1 3 4 Case #1: 1 3 2 Case #2: 4 5 3 2 1 Hint The first case: 1st Second end Player1 100m (BOOM!!) Player2 1…
