using namespace std;

long int T1,T2; vectorarr1; set a;

bool binarysearch(long int s) { long int mid,high=T1,low=0; while(high>low+1) { mid=(high+low)/2;

if(arr1[mid]==s)
        return true;

    if(arr1[mid]<s)
        low=mid -1;

    else
        high = mid +1;
}
return false;

}

int main() {

cin>>T1;
long int q;
for(long int i=0; i<T1; i++)
{
    cin>>q;
    arr1.push_back(q);
    a.insert(q);
}
sort(arr1.begin(),arr1.end());

cin>>T2;

for(long int i=0; i<T2; i++)
{
    cin>>q;
    a.insert(q);
}


long int r1=0,r2=0,ans1=0,ans2=0;
for( set<long int>::iterator i=a.begin(); i!=a.end(); i++)
{
    if(binary_search(arr1.begin(),arr1.end(),*i))
        r1++;

    else
        r2++;

    if(r2>r1)
    {
        ans1+=r1*2;
        ans2+=r2*2;
        r1=0;
        r2=0;
    }

}
cout<<ans1+(r1*3)<<":"<<ans2+(r2*3)<<endl;
return 0;

}

really sorry if i wasn't clear enough !!
