Could someone measure the difficulty of GCJ2018 World Finals? For example, problem "Jurisdiction Restrictions" has its difficulty similar to one Div1C (I don't know, it is only an example), or even "too hard for a regular round at Codeforces". I think it will be great to know this and see how great was the work of the world finalists. I know that this question is a kind of relative, and one question could be hard to one person, and easy for other (tourist), but everyone can expose the opinion about this.
Thanks and congratulations to all world finalists.
PS: Does anyone know how to change my handle? I think it should be "SnapDragonIsTheSecondBestAgainIHope".
