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 _1000
{
    class Program
    {
        static void Main(string[] args)
        {
            while (true)
            {
                string now = Console.ReadLine();
                if (now == null)
                {
                    break;
                }
                int[] x = now.Split().Select(int.Parse).ToArray();
                Console.WriteLine(x[0] + x[1]);
            }
        }
    }
}
