The solution is to sort.Quick sort will be okay.
And pay attention to the string of three symbols "#".
Here is my code:
#include<iostream>
#define maxn 100007
using namespace std;
long n,k,r[maxn];
void Qsort(long *a,long l,long r)
{
long i=l,j=r,mid=a[(l+r)/2];
do{
while(a[i]<mid) i++;
while(a[j]>mid) j--;
if(i<=j)
{
long t=a[i];a[i]=a[j];a[j]=t;
i++;j--;
}
}while(i<=j);
if(l<j) Qsort(a,l,j);
if(i<r) Qsort(a,i,r);
}
int main()
{
/*
freopen("data.in","r",stdin);
freopen("data.out","w",stdout);
//*/
cin>>n;
for(long i=1;i<=n;i++)
cin>>r[i];
Qsort(r,1,n);
getchar();getchar();getchar();getchar();getchar();
cin>>k;
for(long i=1;i<=k;i++)
{
long t;
cin>>t;
cout<<r[t]<<endl;
}
return 0;
}
