Last Problem of the Week this year! Having a bit of trouble with it: In how many ways can seven basketball players of different heights line up in a single row so that no player is standing between two people taller than she is?
Does it have anything to do with 7! or am I on the wrong track completely?

  1. They could line up in ascending order of height.

  2. Is this the only solution? I do apologise for sounding rude, but they are generally more difficult than they appear.

  3. The other solution is lining up in descending order.

    These solutions work. I don't see any reason to complicate this problem. :-)

  4. Check back here to see if another math tutor has other solutions.

  5. Okay. Thank you very much, Ms. Sue, I will.
