Given six integers x_1 x_2 x_3 x_4 x_5 x_6 , you need to sum them \lceil x/2 \rceil times.

Why?
  • Since the cube has 6 faces, you need to buy each x_i one litred colours to paint them. It requries half litre colour to paint one side. Hence, you can simply buy once to paint two cubes.

Code for Reference:

import java.util.*;
import java.lang.*;
import java.io.*;

class Codechef
{
	public static void main (String[] args) throws java.lang.Exception
	{
		Scanner s=new Scanner(System.in);
		int t=s.nextInt();
		while(t-->0){
		    long n=s.nextLong();
		    long x1=s.nextLong();
		    long x2=s.nextLong();
		    long x3=s.nextLong();
		    long x4=s.nextLong();
		    long x5=s.nextLong();
		    long x6=s.nextLong();
		    long cost=0;
		    cost=(x1+x2+x3+x4+x5+x6)*((n+1)/2);
		    System.out.println(cost);
		}
	}
}
