Teacher: Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.
Teacher: Now, understand the problem? If you are still confused, see the following 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: No
Reason: Both participants do not agree to the deal, so the answer is No.

Now, solve this instance: THEM: i'll take the books and hat if you want the balls  YOU: i need the hat and 1 book and you can have the rest  THEM: i cant make that work mathmatecally...... i could do the hat and 3 balls  YOU: the balls have no value  THEM: thats what i was saying i will take the balls and a hat  YOU: i have to have the hat  THEM: i would have to take everything else if you wanted the hat  YOU: how about i take the books and 1 ball.
