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 would like one of each.  YOU: gimme hat  THEM: i will agree to you having all the books.  YOU: hat for me, you take all rest  THEM: nope, i can't agree to that, i need one of each.  YOU: no deal?  THEM: guess it's a no deal.  YOU: waitin for button  THEM: still don't have the no deal button on this side either, final offer one each of the book, hat and ball to me.  YOU: hmmmmm nope.

Solution: No
