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

Sample Output

6
30

代码

 1 #include <iostream>
 2 using namespace std;
 3 int main() {
 4     int a, b;
 5     cin >> a >> b;
 6     while (!(a==0 && b==0)) {
 7         cout << a + b << endl;
 8         cin>> a >> b;
 9     }
10     return 0;
11 }
