And c blue boxes and d yellow boxes.
And they are all made out of ticky-tacky.
And they all look just the same.

Input

The input has several test cases. The first line contains the integer t (1 ≤ t ≤ 10) which is the total number of test cases.
For each test case, a line contains four non-negative integers a, b, c and d where a, b, c, d ≤ 2^62, indicating the numbers of green boxes, pink boxes, blue boxes and yellow boxes.

Output

For each test case, output a line with the total number of boxes.

解題報告：

1：求四個數的和，但是是大數，所以可以直接用java解決。

代碼：

import java.math.BigInteger;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int T = scanner.nextInt();
        for (int i = 0; i < T; i++) {
            BigInteger ans = new BigInteger("0");
            BigInteger x;
            for (int j = 0; j < 4; j++) {
                x = scanner.nextBigInteger();
                ans = ans.add(x);
            }
            System.out.println(ans);
        }
    }
}
