I need a simple Prolog predicate like:
make_list_elements_unique([1,1,1,2,2,3], X) with X = [1,2,3].
Before starting to write it on my own, I want to search for a built-in predicate. I can't suggest that Prolog hasn't such a predicate.
Do you know it?
您可以使用内置谓词sort/2
。
I've found the built-in predicate list_to_set/2 for that!
Works very fine.
