import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.StringTokenizer;

public class Main {
    public static void main(String[] args) throws IOException {

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        StringBuilder sb = new StringBuilder();

        int num = Integer.parseInt(br.readLine());
        int answer = 0;

        for (int i = 0; i < num; i++) {
            answer = 0;
            StringTokenizer st = new StringTokenizer(br.readLine());
            while (st.hasMoreTokens()){
                answer += Integer.parseInt(st.nextToken());
            }

            sb.append(answer).append("\n");
        }

        System.out.println(sb.toString());

    }
}
