Given a negotiation between two participants, answer 'Yes' if both participants agree to the deal, otherwise answer 'No'.

Example input: 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 output: No
Example explanation: Both participants do not agree to the deal, so the answer is No.
Q: THEM: hi there, i'd like the hat and the book. you can have the balls.  YOU: i need the hat, and a ball and the book.  THEM: i can't give you all of that. i need the hat at the very least.  YOU: i absolutely need the hat.  THEM: it looks like we will not be able to reach a deal then. i also need the hat.  YOU: that's not good.  THEM: there is nothing else we can do. the "no deal was agreed" button is time activated.  YOU: should we keep typing?  THEM: it couldn't hurt.  YOU: this is silly.
