The unofficial tutorials of most problems can be found on the forum but yes they should have released the editorial.
Yes, its too long. But I would suggest that we see the unofficial ones, they are by no means any worse/bad than the official ones. In case unofficial ones don’t clarify your doubts, ping us/ask as doubt. We will try to best help you. 
Please i request to all guys that do not post the same question again and again.
