Given two integer numbers, display the sum of those numbers.
给定两个整数，显示他们的总和。

Write a program:
that read two integers from the keyboard and display sum of those numbers.
从键盘读取两个整数并显示这些数字的总和。

First line contains integer N1.
Second line contains integer N2.

Assume that,

Input contains N1 and N2 integer numbers within the range [-2,147,483,648 to 2,147,483,647].
//此范围为long类型数据范围
//int范围 [-2147483648，214748364]，如用int定义，则有一部分数据无法显示

Input

public static void main (String[] args) {
        Scanner sc = new Scanner(System.in);
        long n; 
        long N1;
        long N2;
        N1 = sc.nextInt();
        N2 = sc.nextInt();
        
        n=N1+N2
       
        System.out.println(n);

    }
