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: Accepted)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
	public static void main(String[] args) throws IOException {
		// TODO 自動生成されたメソッド・スタブ
		BufferedReader stdReader = new BufferedReader(new InputStreamReader(
				System.in));
		String line;
		while ((line = stdReader.readLine()) != null) {
			String[] tokens = line.split(" ");
			int x = Integer.parseInt(tokens[0]);
			int y = Integer.parseInt(tokens[1]);
			System.out.println(x + y);
		}

	}
