将数据存入优先队列,优先队列出队顺序按照分数从大到小,设置数组vis[]来标记对应日期是否有空闲时间,
若无空闲时间则必须舍弃当下分数:
#include<stdio.h>
#include<cstring>
#include<queue>
using namespace std;
struct node
{
	int time;
	int score;
	friend bool operator < (node a,node b)
	{
		return a.score<b.score;
	} 
};
int main()
{
	int n,m,j,i,t;
	int vis[2100];
	while(scanf("%d",&t)!=EOF)
	{
		memset(vis,0,sizeof(vis));
		priority_queue<node>q;
		node x;
		for(i=0;i<t;i++)
		{
			scanf("%d%d",&n,&m);
			x.time=n;
			x.score=m;
			q.push(x);
		}
		int sum=0;
		for(i=0;i<t;i++)
		{
			x=q.top();
			for(j=x.time;j>=1;j--)
			{
				if(vis[j]==0)
				{
					vis[j]=1;
					break;
				}
			}
			if(j==0)
			sum+=x.score;
			q.pop();
		}
		printf("%d\n",sum);
	}
	return 0;
}
