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: i'd like the book, a hat and two balls.  YOU: no on the book, you can have 1 hat and 2 balls  THEM: how about i take the book and the hat?  YOU: no deal.  THEM: how about the book and a ball?  YOU: you can have the book if i can have everything else.  THEM: unfortunately, that won't do me much good. i need something with the book.  YOU: that doesn't work for me  THEM: sorry. it's just a bad deal for just the book.  YOU: sorry, guess we have no deal.

Solution: No
