Hi All. Is there any function in Prelude that removes the repeated elements in a list?
In example I've a list like this one: xs = ["3","3","3","3","3","4","4","4","4","4","5","5","5","5","5","6","6","6","6","6","6","6"]
I need a function f such that f xs = ["3","4","5","6"]
thanks in advance for any answer.
