答案：import java.util.ArrayList;
import java.util.Scanner;
public class Text10021 {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
ArrayList<String> arr = new ArrayList<String>();
for(int i = 0;i<=n;i++)
{
String s = sc.nextLine();
arr.add(s);
}
for(String string : arr)
{
String s1[] = string.split(" "); 
if(s1.length==2) {
int sum = Integer.decode(s1[0]) + Integer.decode(s1[1]);
System.out.println(sum);
}
}
}
