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 
        
         int main(){
       int a,b;    while(scanf("%d %d",&a,&b)&&(a||b))    {        printf("%d\n",a+b);    }return 0;}
