It’s disappointing to see participants abusing such techniques to disguise copied solutions, especially when the goal of the platform is to encourage learning and fair competition. The fact that these altered submissions can bypass basic similarity checks undermines the efforts of honest contestants. I respectfully ask the Codeforces team to investigate these cases more closely and consider strengthening detection measures to prevent similar issues in the future.

Dear codeforces

I want to sincerely apologize for my actions in this contest. I didn't think my cheating would have consequences like this.

From how to i hashed code, i learned this on a youtube channel which was deleted 2 years ago (about cheating game and security code), and i used chat gpt to generate the program which can hash my code like this.

I have learned my lesson from this time. I feel I deserve to be punished for this, but in my account i have a lot of course about coding, so i hope i will be forgiven for my actions to continue practice (and skipped all my submission in this contest to roll back my rating).

I promise I won't join any contests after and will only use my account to practice

Against, I apologize for my actions last week, and I knew rating isn't important, it's just a number

Thank you for your understanding, and I look forward to practicing more on Codeforces

Thanks a lot, have a good day!

(Sorry for my bad English)

Code obfuscation is not allowed. This user should definitely be banned.

For the sake of self-education,

dafuq happened in this code at all?

    They used macros to make the code intentionally unreadable. for example if i want int n; cin>>n; i can do:

    #define dQw4w9WgXcQ int
#define j69rH6ehk3P cin
#define fjsoH5G7j5T >>
#define hk8G4ag9DE7 n
#define tj7H5jo9Pj4 ;
//...
dQw4w9WgXcQ hk8G4ag9DE7 tj7H5jo9Pj4 j69rH6ehk3p fjsoH5G7j5T hk8G4ag9DE7 tj7H5jo9Pj4

    And during compilation, This will be transformed by the preprocessor into int n; cin>>n:. This can be done to make hacking their solutions harder and/or prevent cheating detection (another comment says they used if(!(cin>>t))return 0; which is a telltale sign of AI use.)
