Problem:
A + B Problem

Compute A + B.

Input

The input will consist of a series of pairs of integers A and B separated by a space, one pair of integers per line. The input will be terminated by EOF.

Output

For each pair of input integers A and B, you must output the sum of A and B in one line.

Constraints

-1000 ≤ A, B ≤ 1000

Sample Input

1 2
10 5
100 20

Output for the Sample Input

3
15
120

Sample Program

#include<stdio.h>

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

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.*;
import java.io.*;

public class Main {
	public static void main(String args[]){
		Scanner in = new Scanner(System.in);
		while(in.hasNext()){
			long a = in.nextLong(), b = in.nextLong();
			System.out.println(a+b);
		}
	}
}
