hello.. need some help with this qn.. i know that it has been threaded b4.. i still don't know how to solve part (d) no matter how many times i try to trade :(.
question: i am supposed to collect basketball cards from 1-10. currently, i have the cards: 10 , 10 , 9, 9,9,8. How am i supposed to trade with someone else in order to get a complete set of cards from 1 - 10?
rules of trading:
1. you give the person two cards and ask for three which add up to the same value as your two ( e,g, you could give him 8 and 6 and ask for a 7,a 4 and a 3, or two 5's and a 4.)
2. You cannot ask for a higher card than the best one you gave him.
(e.g he won't trade your two 8s for a 10, 5 and 1.)
3. He never does a two-for-one swap ( e.g. if you give him a 9, he won't give you a 7 and a 2)
4. You cant scam him by trying to give him a 9 and a 6 for a 7 a 6 and a 2.)
