import java.io.*;

public class Main {
    public static void main(String[] args) throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));
        int num = Integer.parseInt(br.readLine());

        for (int i = 0; i < num; i++) {
            String[] s = br.readLine().split(" ");

            int a = Integer.parseInt(s[0]);
            int b = Integer.parseInt(s[1]);

            bw.write(a + b + "\n");
        }
        bw.flush();
    }
}

 

StringTokenizer 사용

        BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(System.out));
        int num = Integer.parseInt(br.readLine());

        for (int i = 0; i < num; i++) {
            StringTokenizer st=new StringTokenizer(br.readLine());

            int a = Integer.parseInt(st.nextToken());
            int b = Integer.parseInt(st.nextToken());

            bw.write(a + b + "\n");
        }
        bw.flush();
    }
