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; }
