I think this judge is wrong, there are so many wrong answer, and the output format isn't clearly described in the problem.
Such as the output sequence, is there a leading space every new line? The problem did't say but the format does have.
Could you check this problem please?

As a general advice, you should follow sample output's format. For this particular problem, output should contain a space before all lines describing the sequence.

Judge's output for this problem was completely wrong. We've changed it and we're rejudging all submissions.
