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

题目大意

求多组数据两个数的和，以a,b均为0结束。

代码

<span style="font-size:18px;">#include<stdio.h>
int main()
{
    int a,b;
    while(scanf("%d%d",&a,&b)&&(a!=0||b!=0))
    {
        printf("%d\n",a+b);
    }
    return 0;
}
</span>
