I modified the description. It seems that the confusion was only for a few ones:-) Maybe you could have a look to tell me if it suits you.
Have a good day.

Well, see computerguy103's comment below:

Okay then can the description be edited to indicate which languages should eliminate duplicates, and which shouldn't worry about them?

At this point, you're the only one who can fix the confusion (and use this chance to add formatting to the description).

Read what Zozo said below. I didn't mention duplicates; it was your idea when you did the HS translation...

@g964: However, if you mention them explicitly, make sure to handle them in your tests. :D

(Yeah, 500+ solutions and so on, I know)

Thanks for the feedback but read posts below about duplicates:-)
