尼玛,这么水In Reply To:Re:太水了!!! Posted by:lifanglin at 2012-05-24 09:40:16 对于其他单车选手A,如果他在能超过小明,那么小明就会与A同速。从整体来看,小明是所有选手中最早到达目的地的,因为他总是在其他选手的前面。
int main()
{
double x,y,ans,tmp;
int i,n,len;
while(~scanf("%d",&n)&&n)
{
ans=9999999999;
for(i=len=0;i<n;++i){
scanf("%lf%lf",&x,&y);
if(y<0)continue;
x=x*5.0/18;
tmp=4500.0/x+y;
if(tmp<ans)
ans=tmp;
}
printf("%.f\n",ceil(ans));
}
return 0;
}
