Order dependent answer checkers.

Description:

Task 2 states that List<String> of unique names must be returned, but ordering is not specified.

The issue can be replicated by taking the right solution:

    public List <String> task2 (List <String> names) {
        List<String> result = new ArrayList<>(List.copyOf(Set.copyOf(names)));
        return result;
    }

Which passes the tests and then applying Collections.shuffle() to it, like this:

    public List <String> task2 (List <String> names) {
        var result = new ArrayList<>(List.copyOf(Set.copyOf(names)));
        Collections.shuffle(result);
        return result;
    }

The resulting solution must pass tests according to the statement, but it doesn't.

Actually yes, it's bug
