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'd like to have the two hats and book YOU: how about you can have the two hats and one ball, i keep the books and 1 ball... right down the middle. THEM: not much for sports, balls don't do much for me. YOU: well, they do not help me at all, so i'd prefer we meet down the middle somehow. do you propose anything different? THEM: alright, i'll take two hats and the two balls if they don't do a thing for you. YOU: and we're still going to roll with an uneven split. in that case, i'll take the books and a hat, then? THEM: yes sir.
