Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.

Let me give you an example: THEM: i need the hats and the ball  YOU: i can give you one hat and the ball. i want 2 books and 1 hat  THEM: i have to have both hats and the ball or both hats and a book to make a deal  YOU: sorry, i won`t make a deal without a hat  THEM: if you take 1 hat i have to have everything else  YOU: sorry can`t do  THEM: no deal  YOU: yesh no deal, sorry  THEM: no deal  YOU: no deal.
The answer to this example can be: No
Here is why: Both participants do not agree to the deal, so the answer is No.

OK. solve this:
THEM: hi. i'd like four hats and the book, leaving you with two balls. what do you say?  YOU: that could not be fare...  THEM: what are you offering?  YOU: i need one book and the hats  THEM: i definitely can't give up the hats. how about you take the book and the balls, and i get the hats.  YOU: that sounds good  THEM: ok great. i get all the hats, you get the book and both balls. deal?  YOU: no no, wait  THEM: what?  YOU: that's very raw deal  THEM: ok, well then we're not going to make a deal, because i am not giving up any hats.  YOU: no deal then.
Answer:
No
