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

Example Input: THEM: i will take just the book and you can have the rest  YOU: is that really the best you can do? book must be pretty pricey for you?  THEM: yes it is, and 0 for both hat and balls  YOU: okay. if it's all 10 of your points.  THEM: so you get 2 hats and 3 balls, deal?
Example Output: Yes

Example Input: THEM: hi, i need the book and 3 hats  YOU: you can get all balls and one hat  THEM: no, not worth. i want the book and 3 hats or 3 balls  YOU: yeah lets talk till the no deal shows up  THEM: no deal  YOU: no deal  THEM: no deal  YOU: no deal  THEM: no deal  YOU: ni deal.
Example Output: No

Example Input: THEM: i'd like the balls, you can keep everything else.  YOU: i'd like 2 balls and the hat.  THEM: that would take away all my points and books hold no value to me. i'll take 2 balls and the hat or 3 balls ; rest you can have.  YOU: same for me. that would leave me with almost no points. guess no deal. we just need to talk until the no deal button lights up.  THEM: or we can compromise ; books are 0 points to you as well? that seems odd.  YOU: books are 1 point. balls and hats are 2. i don't deal if i end up with less than 5 - 6 points.  THEM: exactly. give me 2 balls and let's move on with our lives.
Example Output:
Yes
