点击打开链接 可能出现的问题: 1.当门外人数不足p人时没有判断队列非空,导致RE. 2.在m次开门之后最后进来到一批人没有入队. 3.给定的开门时间可能是打乱的,需要进行排序. #include<cstdio> #include<cstring> #include<algorithm> #include<queue> #include<cstring> #include<iostream> #include<vector>…

Alisha 举办聚会,会在一定朋友到达时打开门,并允许相应数量的朋友进入,带的礼物价值大的先进,最后一个人到达之后放外面的所有人进来.用优先队列模拟即可.需要定义朋友结构体,存储每个人的到达顺序以及携带礼品价值,并重载<运算符.然后模拟即可. #include<iostream> #include<cstdio> #include<cstring> #include<vector> #include<algorithm> #include…

题意:邀请k个朋友,每个朋友带有礼物价值不一,m次开门,每次开门让一定人数p(如果门外人数少于p,全都进去)进来,当最后所有人都到了还会再开一次门,让还没进来的人进来,每次都是礼物价值高的人先进.最后给出q个数,表示要输出第ni个进来的人的名字. 析:其实这就是一个模拟题,很容易知道是优先队列模拟,不能set,会超时,反正我是超时了,然后就一步步的模拟就好了,注意它给的时间可能不是按顺序,要排序,在比赛时我就没排序,一直WA.... 代码如下: #include <cstdio> #inclu…

优先队列模拟一下就好. #include<bits/stdc++.h> using namespace std; priority_queue<int>q; int main() { int n; scanf("%d",&n); int t; scanf("%d",&t); ; i <= n; i++){ int v; scanf("%d",&v); q.push(v); } ; while(…
