(Nthcdr n l) removes the first n elements from the list l.
The following is a theorem.
(implies (and (integerp n)
              (<= 0 n)
              (true-listp l))
         (equal (length (nthcdr n l))
                (if (<= n (length l))
                    (- (length l) n)
                  0)))
For related functions, see take and see butlast.The guard of (nthcdr n l) requires that n is a nonnegative
integer and l is a true list.
Nthcdr is a Common Lisp function.  See any Common Lisp
documentation for more information.
To see the ACL2 definition of this function, see pf.
