Define a prolog predicate flatten, Programming Languages

Assignment Help:

Define a Prolog predicate flatten(List, FlattenedList) that asserts List is any nested list of atoms and FlattenedList is the same list with the nesting removed. The atom [] should also be removed. Your predicate should only produce one answer. You may use the built-in predicates not, ! and append. Do not use a helper predicate.
