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;
using System.Linq;

namespace AOJ
{
	class Program
	{
		public static void Main(string[] args)
		{
			string s;
			while((s = Console.ReadLine()) != null)
			{
				var n = s.Split(' ').Select(i => int.Parse(i)).ToArray();
				Console.WriteLine(n[0] + n[1]);
			}
		}
	}
