Your task is to Calculate a + b.
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.
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.
