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'l take balls and book if you want the hats  YOU: you can have all the balls if i get the book and the hats.  THEM: i would need one of the hats and the balls to at least get 5 / 10  YOU: i can do that. i get the book and one hat, you get the rest.
Solution:
Yes
