Feb 7:
• A nested list is s list, one of whose elements is itself a list. E.g., (1 (2 3) 7 10) is a nested list.
• A flat list is a list that is not nested. E.g., (1 2 7 10)

Feb 7: Your procedure should also work with flat lists.

E.g., (topsyturvy2-4 '(1 2 3 4)) returns (1 4 3 2).

Feb 3: There is a typo in Question 3. Thanks to Janos for catching it.

(else (unknown (cdr a-list) c1 c3 c3))

should be:
(else (unknown (cdr a-list) c1 c2 c3))

Write a predicate procedure (palindrome? lst) where lst is a list, that tests to see if lst is a flat list and if it is that has the same ...

The word that should have been the word flat.
