This is a dark theme userscript for vjudge

Today I was looking for one but can't find any so I decided to make one, inspired by sigma_g's Codeforces dark theme (link to blog here).

This is the bare minimum of dark theme. Anyone is welcome to use and contribute.

There will be updates and improvements later.

Btw, I will be solving 1600-1900 CF Edu problems in the near future. If anyone interested to join me in vjudge let me know!

Hi everyone,

I write this blog because I encountered a rather weird issue, maybe anyone here has the same issue or even has solved this?

I was participating in a contest earlier when I tried to compile & run for problem B and my code doesn't run >︿<

My case:

This code below compiles and run, I can see Hello printed in my terminal

#include <bits/stdc++.h>
using namespace std;

int main() {
  vector<int> v;
  cout << "Hello";
  // v.push_back(2);
  return 0;
}

However when I uncomment v.push_back(2) it compiles but doesn't run! (I don't see Hello in terminal)

Commands I used: g++ main.cpp -Wall -o main .\main.exe

There's no warning or error message.

I have tried compiling with MSYS64 (my main) and MSVC x64, same results.

Yesterday it was working fine, so maybe something broke my c++ runtime today.

Here's a list of what I did today before running to this problem:

  • installed Anaconda,
  • installed git,
  • installed Visual Studio and C/C++ build toolchain (for rust),
  • installed rust

Similar problem: https://stackoverflow.com/questions/70809283/c-program-does-not-run-if-a-vector-has-any-contents https://stackoverflow.com/questions/70994977/c-code-wont-run-if-a-vector-contains-value

I'd love to participate in that post's comment section however I don't have enough karma.

Someone mentioned this, tho I haven't tried.

Spoiler

Then I tried Visual Studio IDE and it works! Sadly VS complains when I do int arr[n]; saying array size should be static.

I'm considering IDEs since text editor has this issue (I implied IDE is OK because Visual Studio is OK), maybe I'll go with DevC++ or farmanager, or even code in Rust.

I'll share some update if this blog doesn't get >10 downvotes

They knowingly hacked their own code...

I suppose this hack is illegal? Will codeforces detect this automatically or someone has to report this?

Edit

 if(n == 3 && a[0] == 228 && a[1] == 1337 && a[2] == 228){
        cout << "HACKED LOL" << endl;
        return;
 }

for those who doesn't bother reading the submission
