This problem is too easy!
Here is my code:
#include<iostream>
#define maxn 107
using namespace std;
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);
//*/
long k,r[maxn],ans;
cin>>k;
for(long i=1;i<=k;i++)
cin>>r[i];
// Input
Qsort(r,1,k);
// Qsort
ans=0;
for(long i=1;i<=k/2+1;i++)
ans+=(r[i]/2+1);
cout<<ans<<endl;
return 0;
}
