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: what would you like  YOU: i'd like the books and balls ; hat is no use to me. make me an offer.  THEM: i need the balls but you can have the rest  YOU: hat any value to you? you wouldn't be interested in 3 books, 1 ball for me would you? : )  THEM: hat has no value for me...  YOU: alright. is it 0 or minimal value? i'll take books, but we need to know who gets the hat. i don't need it.  THEM: i'll take it.

Solution: Yes
