    I think using Chinese on CodeForces is not appropriate.

      Why? I thought codeforces is a platform for everyone.

        Because of the community rules.

          Which one? I read the rules but I didn't find "DO NOT USE CHINESE".

            Maybe you're right, there's nothing in the community rules about what language you have to use. But I have been warned for using Chinese. I think it is not allowed.

        Why is most of the comments in this post downvoted? Is there anyone doing that on purpose?

    You can farm contribution as tester or writer

    But don’t mention that. That’s inappropriate.

As we know,Usually a post for Q&A and a summary would be published in Luogu.I think Luogu should also post something like these on CodeForces for people from other countries

    "You must submit your code at the Chinese version of the statement" It would help if you changed the statements to Chinese and then submit them. I got the same error when trying to submit solutions in English statements

I don't think the internationalization of luogu is a good idea,because it's almost impossible to turn everything into English.

For Problem D, My Construction was,

1. check if the graph is tree or disconnected.
2. find bridges in the graph.
3. color all the bridge nodes in the graph as black.
4. if there are remaining uncolored node, then color them as white.
5. else, if all the nodes are colored black, then there should a node which has degree 1. color that vertex as white and move up, until there is a node (u) having degree > 1. at last, color the node u as white.

this construction gives wrong answer.
can someone find a testcase on which this construction fails.

Thanks in Advance!
