1000: 整数a+b

C/C++版

#include <stdio.h>

int main(void )
{
    int a,b;
    scanf("%d%d",&a,&b);
    printf("%d\n",a + b);
    return 0;
}

Python版

import sys
a =input()
n,m = a.split(' ')
print(int(n)+int(m) )

Java版

import java.util.Scanner;
import java.math.BigInteger;
public class Main{
	public static void main(String[] args){
		Scanner in=new Scanner(System.in);
        // 可以不用大整数
		BigInteger a = in.nextBigInteger();
		BigInteger b = in.nextBigInteger();
		System.out.println(a.add(b));
	}
}
