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

#include<stdio.h>

int main()
{
    int num1, num2;
    while(scanf("%d%d", &num1, &num2)!=EOF){
        if(num1==0 && num2==0){
            continue;
        }
        printf("%d\n", num1+num2);
    }
    return 0;
}
