Hey MD,

I have a very serious rule that I won't answer questions that haven't been written grammatically. This is because it signals one of two things. Either:

a) The question has been copied down incorrectly, in which case mistakes might have been introduced.

b) The question comes from a source that is too lazy to use correct grammar, in which case the questions can't be trusted.

This question doesn't make sense yet, because it isn't clear if we have to use those numbers once, or if we can only use those numbers once. And there are other grammatical errors. Can you repost it with correct grammar?
