  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.
