Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.
One 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.
Solution is here: No
Explanation: Both participants do not agree to the deal, so the answer is No.

Now, solve this: THEM: i need the three books and atleast one hat  YOU: i can not make that deal as i need the same. are the balls worth anything to you  THEM: no balls nothing worth to me  YOU: for me as well. can we split the difference if i can have two books, one hat, and one ball you can have the rest  THEM: okay then give me atleast 2 hats and one ball and one 1 book  YOU: splitting the difference is not you getting two hats. we both needed the hats. one hat each.  THEM: well you want two books as well so you need to be fair here too! @  YOU: there are three books not two so they would have to be split. i want to make a deal but, it doesn't look like that is going to happen  THEM: so you want what??  YOU: i want two books one hat and one ball.
Solution:
No
