I asked a question before, but I failed the solution I made. Then I made an almost completely different attempt to eliminate all errors. I re-posted the question, since editing the old question will override the existing answer. Does the MSE rules allow me to do this? (I got downvote) But, there is a truth. That is the extreme effort I made.

By the way, can I send new solution for questions I have previously failed?

    $\begingroup$ You got one downvote. Big deal. Probably someone's cat walked across his keyboard. $\endgroup$ Feb 23, 2020 at 11:08
  • $\begingroup$ @GerryMyerson Ohh, my english is insufficient so it could be misunderstanding. Taking Downvote is extremely natural. My concern is, did I act against the rules? $\endgroup$ Feb 23, 2020 at 11:11
  • $\begingroup$ Sorry, it looked like you were concluding that m.se didn't like your question on the basis of it receiving a downvote. $\endgroup$ Feb 23, 2020 at 11:15
