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 C# (judge verdict: Accepted)

using System;

public class p1000
{
	p1000(){
		string str;
		string[] st;
		
		while((str=Console.ReadLine()) != null){
			st = str.Split(' ');
			Console.WriteLine("{0}", (int.Parse(st[0])+int.Parse(st[1])));
		}
	}
	
	public static int Main(string[] args){
		new p1000();
		return 0;
	}
}
