Can you tell me how to delete it?

Once it has a reply you can't delete your post, but it is fine, just remember to mark your post as having spoiler content (when posting code like this in a solution) and it won't be visible in the home page. This time I've marked both your posts for you.

Why are you posting again a solution without marking your post as having spoiler content?

I dont know how to delete the comment, i was training to do another thing.
