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: evening! how would it sound to you if you got to keep every single hat? i'll be happy with the book and both balls.  YOU: no deal. i will take the hats and one ball and you can have the rest  THEM: i absolutely can't part with a ball. i'm prepared to let you have the book and the hats, though.  YOU: deal.

Solution: Yes
