Google-forces round 810 :

Google-forces round 808 :

Google-forces round 805 :

This shows nowadays we need to learn Chinese language and improve our searching skills, But this isn't fair, MikeMirzayanov What's your opinion about this?

P.S : Every single thing I say in the comments is just my opinion and never wanna insult any country/organization/person and etc.

1044F is a harder version of round 808 problem C(I wasn't aware of it in contest).I came across this problem today while randomly solving 2700s on CF.Its probably a coincidence.

Bad point: I'm so sad because I got a lot of penalties at div1B at round 808. Good point: I become orange by messing few rounds, I'm not on a wrong way.

Two problems being similar does not necessarily mean it is copy-pasted. Maybe it is a coincidence and the author just did not know about it.

    According to this blog : https://codeforces.com/blog/entry/105221 That problem was completely copy-pasted Also in other two rounds that I've mentioned the problems are exactly the same as the source, So maybe you're right sometimes it's consodence but not for these rounds!

Speaking specifically about 808 Div2D, the authors proposed the problem long before an equivalent problem appeared on Codechef, so it is certainly not copied from Codechef.

I also know myself what it is like from my own contests to come up with a problem I love, and to have checked very carefully if it appeared before, only to find out on contest day that it appeared before.

We are doing everything we can to avoid unoriginal problems by having experienced testers look at the problems, but some will inevitably slip through given the huge number of problems out there and no team of testers will have seen all of them.

    Basic Chinese may not be difficult, but it may be difficult to chat normally and understand each homophonic stem.For example.理解这个或许有“亿”点困难。

      Understanding this may be difficult with "billions"

        This is a common meme in Chinese and it seems that you are using a translator. It is saying that learning Chinese is difficult in a humorous way.

        here the 亿 (yi with the tone going down)== 100 million and 一 (yi with the tone staying high) == 1 have a very similar pronunciation, which tricks stupid foreigners like me up!

        We try to say "one bit" and end up saying "100 million bits" without realizing it. (Or the other way around, like Zuck when talking about his user number in Chinese)

        EDIT: Ok I'm wrong it actually sounds the same here (see ACGN's comment), the pronunciation of the one character "一" depends on the context!

          Actually, when saying "a bit" (一点), the tone of the "一" (yi) also goes down in the same way as 亿 (yi) because of some rules regarding tone. Thus, phonetically, 一点 (a bit) is the same as 亿点 (a billion bits).

            great to know, thanks for correcting me! The more Chinese I learn the more I get confused about the pronunciation!!

            Does anyone know any good learning resources about pronunciation variation for those characters where it changes depending on the situation?

If div1C/ div2E is also copied then why div2 is not unrated?

        Have you even bothered to use Google Translate?

        The Chinese version is

          n <= 2^30
          a XOR b XOR c = 0
        

        whereas in the div1C

          n <= 2^200000
          WLOG a < b < c, a XOR b + b XOR c > a XOR c
        

        They only have similarities and are totally different problems, unlike div1E.

CodeTON Round 2 is also Chinese round, I knew some of the writers before, so I hope that round will be better.

Learning chinese is difficult but sometimes interesting! but chinese students have to learn english in class so they can make sentences and understand english tasks easily.

Maybe I don't think you can learn Chinese well like I can't learn stupid English well,and considering Chinese is a little bit more difficult,ther is no need for you to learn it just for coding,and the quality of these competitions are not that high.So maybe learning Chinese is a stupid choice.

OK. For Chinese OIers like me, we need to learn the English language to read problem statements on some programming websites like Codeforces. You said that it's not fair to learn Chinese, but please think about people who have difficulty learning English, then you will feel better.

    Bruh, First of all you don't need much knowledge of English to read the problems on codeforces, Second is learning English is much simpler to learn Arabic or French or Chinese

        My mother tongue is Persian, And I don't say that learning English is piece of a cake but it's much easier to learn English than Persian or Arabic and etc.

          Everyone has his own idea, but you can't say learning Chinese for you is unfair. Chinese people may think them are discriminated against by you.

您好,我是一名来自中国的信息学奥赛选手。I'm an OIer from China. Chinese people maybe think the Chinese language is straightforward to learn. But it's not true. When we learn English in China, we need to know so much grammar and spend so much time reciting words. Although I have learned English for six years, I still can't write this passage very smoothly. There are more grammar and words in Chinese. It's very difficult for People in another country. So I have some suggestions. If you are a very “强” (excellent) OIer and will communicate with Chinese OIer, I think you can learn some Chinese knowledge (but in fact, most excellent Chinese OIer are fluent in English). If you just want to see the problem on some Online Judge, you can simply understand the professional terms and basic content. There is no need for systematic learning. That's a waste of time. After all, Google Translate can translate Chinese more accurately. Or you can try 百度翻译 (Baidu Translate): fanyi.baidu.com

This isn't fair that we should learn English to improve our Programming Skills too. Learning has no border, and I think learning Chinese is no need for you if you don't want to study it. Follow your heart. There are many ways to improve searching skills.
