版本一

// 输入挂
Scanner cin = new Scanner(new BufferedInputStream(System.in));
// 输出挂
static BufferedWriter print = new BufferedWriter(new OutputStreamWriter(System.out));
// 示例
import java.io.BufferedInputStream;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.util.Scanner;

public class Main {
    static BufferedWriter print = new BufferedWriter(new OutputStreamWriter(System.out));
    public static void main(String[] args) throws IOException {
        Scanner cin = new Scanner(new BufferedInputStream(System.in));
        int n = cin.nextInt();
        for (int i = 0; i < n; i++) {
            int a = cin.nextInt();
            int b = cin.nextInt();
            print.write(a + b + "\n");
            print.flush();
        }
    }
}
