    if he stole first problem solution, he stole all the solutions =) so, ban him! :P

    just kidding

    Not only he stole it, but also went back in time to reduce the time penalty. People will now time travel just to save their ratings, smh...

      They even do that for unrated contests just to look cool

    I knew it, I knew it. The time machine exists.

    Yeah, I was thinking the same. I compared both codes, and they are almost the same (well the code in the main function are exact in both of them). I am not saying that you guys cheated (ofc it just don't make sense to cheat when you both were out of competition), but just imagine how many ways would be there to write the code in the main function. There would be trillions of them (these possibilities would be reduced a lot if possibly BERNARD is inspired by tourist in the way of writing codes or vice versa. Is it so?). Anyways, It's just cool to imagine that out of all these ways, there were 2 codes that were the same.

Even in this case tourist's submission is faster than yours

How are you generating the author and created comment in your code? (I hope its not manual)

    CP EDITOR HAS THIS INBUILT FUNCTION.

      Is there any way to do this in VS Code?

        Don't Know!

        • 44 hours ago, # ^ |

          OK, no problem

      • 39 hours ago, # ^ |

        I use VS Code to create it.

  • 38 hours ago, # ^ |

    For VS Code.

    • Press Ctrl + Shift + P (or Cmd + Shift + P on macOS) to open the Command Palette.

    • Type Preferences: Configure User Snippets and select it from the dropdown.

    • Choose the language for which you want to create the snippet (e.g., C++).

    • In the opened snippet file, add the following snippet:

    Spoiler
    • Save the file.

    Now, whenever you type header and press Tab, it will insert the comment template with the current date and time.

and it is also impossoble to increase rating if you solve simple enough problems

That moment when whitespace tells you more than the code itself…
