| Keep the boxes and their car pointers in the same places as the first
| diagram and just move the cdr pointers.

  in the interest of being the least _directly_ helpful on this homework
  assignment, isn't he better off keeping the CDRs and swapping the CARs?

| PS: Are they called "first and rest pointers" these days?

  never seen these function names used to name "pointers".  CAR and CDR are
  still the low-level implementation details of a CONS, while FIRST and
  REST refer to a particular view of the CONS, namely when used as a list.
