##### The great kian `Hackerearth`

The great Kian is looking for a smart prime minister. He’s looking for a guy who can solve the OLP (Old Legendary Problem). OLP is an old problem (obviously) that no one was able to solve it yet (like P=NP).

But still, you want to be the prime minister really bad. So here’s the problem:

Given the sequence a1, a2, …, an find the three values a1 + a4 + a7 + …, a2 + a5 + a8 + … and a3 + a6 + a9 + … (these summations go on while the indexes are valid).

Input

The first line of input contains a single integer n (1 ≤ n ≤ 105).

The second line contains n integers a1, a2, …, an separated by space (1 ≤ ai ≤ 109).

Output

Print three values in one line (the answers).

```#include <iostream>
#include <vector>
using namespace std;

int main()
{
long int n,c=0,a1=0,a2=0,a3=0;
cin>>n;
while(c<n){
int x;
cin>>x;
a1+=x;
c++;
if(c>=n)
break;
int y;
cin>>y;
a2+=y;
c++;
if(c>=n)
break;
int z;
cin>>z;
a3+=z;
c++;
}
cout<<a1<<" "<<a2<<" "<<a3;
return 0;
}```

int x;
cin>>x;
a1+=x;
c++;

}```
