Problem Description

Your task is to Calculate a + b.

 

Input

Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.

 

Output

For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input. 

 

Sample Input

1 5 10 20 0 0

#include<iostream>
using namespace std;

int main()
{
	int a,b;
	while(cin>>a>>b)
	{
		if(a==0 && b==0){
			break;
		}
		else
			cout<<a+b<<endl;
	}
	return 0;
}
