#include<stdio.h>
int main()
{
    int n,i,j;
    scanf("%d",&n);
    for(i=1;i<=n;i++)
    {int a,b,sum=0;
    scanf("%d%d",&a,&b);
    sum=a+b;
    printf("%d\n",sum);

    }
    return 0;
}

java简单实现

import java.util.*;

public class Main {
    private static final Scanner scanner = new Scanner(System.in);
    public static void main(String[] args) {
        var t = scanner.nextInt();
        while (t-- > 0)
            System.out.println(scanner.nextInt() + scanner.nextInt());
    }
}
