Launching a New Tool for Competitive Programmers: The First Code Compiler with Hacking Capabilities!
By shisukenohara, history, 40 hours ago, In English

Link To My Website

Try It Out!!

Features

The website allows you to run code with stdin in Python3 or C++17 and it also allows you to smoothly try to hack someone else's solution smoothly via manually written test cases or generator (PS: It also tells if the code gives TLE or MLE).

  • Edit: As pointed out by near_ai, A new feature is added that doesn't let you run malicious code or the code which can potentially be harmful for the system.

Motivation

As a competitive programming enthusiast, I always wanted to hack a solution but as of now even after being a Codeforces Expert, I have never successfully hacked a solution.

As of now there are multiple websites that allow one to write code with stdin but there is nothing that makes it smooth to hack someone else's code via manual test cases or generator smoothly (at least I didn't find one), so I made one.

Thanks! I was trying to run something like

import os
def fork_bomb():
    while True:
        os.fork()  

fork_bomb()

After that you can get: Request failed: TypeError: Load failed (even after reloading the site).

    Thank You for telling Um_nitsa,

    I have fixed the issue by restarting the service

    Actually, my services are deployed on Render's free tier due to which there are frequent memory and spinning down issues.

    Thank You again for telling.

        Sorry For Inconvenience, Sometimes Due To Peak Concurrency Race Condition Occurs As My Server Has Very Low Memory, I Will Soon Shift To Safe Sandboxing To Fix It. I am Also Thinking Of Adding Some Extra Features Which Will Increase Efficiency.
