    This looks correct to me. In which case number does your code fail?

        hmm, maybe make sure that you have initialized everything correctly (init the dsu, init opp to -1)

          Ohh, I somehow deleted the memset (for -1 initialization) line.

          Thank you very much for your help!

Problem: D

Can anyone explain why my code didn't pass?

I exactly did the same things written in the editorials.

Are the test cases available to download somewhere? (I'm trying to debug my solution to G).

Hey, I can't access the editorial. Also, is there a way to view other's submissions?

    Hi there, the editorial seems to be fine on our side. Maybe it's a problem on your side?

    Regarding viewing submissions of others, the feature has not been added yet sadly.

      Yeah it's working fine now. Since submissions are not visible I think it would nice to have a tester or setter's code in the editorials to get more thorough with the implementation details(for at least noobs like me). Thanks!
