Calculate a+b. Many of the topics test data will have many groups, generally our online system does not write specific requirements, the input is the end of EOF. The basic framework of the problem is as follows:

int main ()
{
   int A, B;
   while (scanf ("%d%d", &a,&b)!=eof)     //Pay special attention to the wording of this line
   {
       ...//sum
       ...//output
   }   return 0;
}

The scanf function has a return value, and if a number is successfully read from the keyboard, the return value is 1, and if 2 is read successfully, 2 is returned. If the end of the file is processed, EOF is returned
Special Note: The requirements of the topic actually refers to the end of each set of data input, immediately output the results of this group, rather than waiting for all the data after the output results

Input

Input as multiple sets of test data. Each row, enter 2 integers a and b per line

Output

For each set of test data, output one line and output the value of a+b until the end of the file

Sample Input

1 12 23 3

Sample Output

246
