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.Collections.Generic;

namespace Volume10_1000
{
	class Program
	{
		static void Main(string[] args)
		{
			List<int> sums = new List<int>();

			do {
				string str = Console.ReadLine();
				if(str == null) {
					break;
				}

				string[] vs = str.Split(' ');
				int a = int.Parse(vs[0]);
				int b = int.Parse(vs[1]);

				sums.Add(a + b);
			} while(true);

			foreach(int sum in sums) {
				Console.WriteLine(sum);
			}
		}
	}
