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: i'll take one of each.  YOU: i will give you all 3 basketballs if i get the book and hat  THEM: no, you may have all three balls and i will take the book and the hat.  YOU: if you give 2 balls and the hat we could have a deal  THEM: i must have the hat. the balls are 0 to me.  YOU: give me all 3 ball and the book and we have a deal  THEM: deal.
Answer:
Yes
