With respect, that is a terrible suggestion. The whole purpose of the
exercise is to gain experience using the design recipe with trees and
to gain experience with using append. After solving the problem using
the DR, Charlie, take a look at the suggested site to discover that
you obtained the same result without "cheating."

You can not learn how to exploit structural recursion by copying
answers from others.
