It has happened that another community member posted a partial answer to a question which I had answered. Now mine is imperfect and his is incomplete. Should I edit mine to have one complete answer? If he did not want to provide a full solution, should he have made a comment instead of posting the answer, such that I could have improved mine?
Weakly related Incomplete answers
edit: I clarified the last sentence.
edit2: Generalised the question. I never intended to attack anyone but thought the example did not hurt.
