I've recently asked this question. As pointed out correctly by one of the commenters, there is a (completely in context) error in my description. Also, my general attempt to solve the question I posted (as described in the question body) is either wrong, or confused and useless in the context of solving the question.
On one hand leaving the question 'as-is' keeps the correct context for the comments and answers, on the other hand - the question description contains wrong or unhelpful ideas.
Should I edit the question and remove the wrong \ unimportant parts?
