Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.
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.
Example solution: No
Example explanation: Both participants do not agree to the deal, so the answer is No.

Problem: THEM: both hats, you get the rest  YOU: i can do that if you include one book.  THEM: so 2 hats and a book for me?  YOU: sorry, meant exchange a book for a hat in your initial offer.  THEM: hats i like alot, they fit perfect  YOU: i bet they look good on you, but my head is cold and needs a hat.  THEM: ok, how about 1 hat a piece, but i get 2 books and the ball  YOU: let's split the hats, and then you can have any two books you want and i keep my ball.  THEM: deal  YOU: ok.

Solution: Yes
