Very nice site
Back to General discussions forum
Heya, I'm really enjoying this website. I solved a lot the last days at work and today I decided to register :)
Would be great to see some harder ones or maybe different programming languages.
Keep up the good job!
Dunno what you mean. If you think of another person or bot, then you are definitely wrong. The first +-100 challenges can be done within a short amount of time.
Some challenges are identical to other websites.
Kinda love the website, layout and ideas.
PS: if you have any questions about my codes or challenges I solved, don't hesitate to ask me.
Quite frankly, I do not believe you. I am 100% convinced that you use GenAI to write your code. It is absolutely possible to do 150 solutions in a short period of time, e.g. a few days, for a good, experienced programmer. However you would expect to see a somewhat consistent programming style in that case. That's not all the case for your solutions. You want examples? Here we go:
- Inconsistent use of
sys.stdin.read()or not for reading inputs - Inconsistent use of
""vs'' - Inconsistent use of
if __name__ == "__main__" - Inconsistent use of comments and approach to naming methods
- For good measure, two random (unsuccessful) C/C++ submissions for Brainfuck problems. If you had read the problems, you would have known that the code should have been in BF.
In addition, you write that you would like to see some harder problems. If you had really solved the problems yourself, you would know that some of them are anything but simple.
Uff. Let me try to explain your points.
“Inconsistent use of sys.stdin.read()” This is not evidence of AI. It is a normal choice based on the problem. For larger input, sys.stdin.read() can be convenient or faster. For simpler problems, input() is simpler. Many coders mix this like me.
“Inconsistent use of \"\" vs '’” Many programmers do not enforce one quote style unless using a formatter. On short contest/problem solutions, quote style is often whatever was typed first.
“Inconsistent use of if name == 'main'” Also not evidence. In standalone scripts it is optional. Some people include it from habit, some omit it for tiny submissions.
“Inconsistent comments / naming / method style” Again, normal. Short challenge solutions are not written like a polished library. Some problems need helper functions, some do not. Some are commented, some are not. When solving many problems across days or weeks, style varies.
“Two wrong C/C++ submissions to Brainfuck problems” Here you are almost right. I did not read correctly. I created the codes at work, run them at home. No option for me testing them at work (no permission). For me it is proof of being human. Sorry for that lol.
“If you solved them yourself, you would know some are hard” This is subjective. Difficulty varies by background. A problem that feels hard to one person can be routine to another, especially if it matches experience in parsing, DP, graphs, math, or implementation. Here I'm with you, yes. My words belong to the first challenges I've solved. Sorry for these circumstances.
I just dont get why you are that toxic? I just wanna say thanks for this great website and you started this forum discussion.
Hi Friend and thanks for your kind words!
I created this more than dozen years ago and myself leant much from the process, from the problems I created, and from the feedback and problems created by others :)
However during recent years here is a sad phenomenon of people wasting their time to "solve" problems using more and more advanced AI tools. That's what our colleague Mathias is meaning in the notes above.
I don't know what drives people to do such a useless work, but of course it is somewhat disheartening for me and other decent colleagues. It is devalueing my and other's efforts, you see.
In your case, as Mathias noted above, it is laughable to see that obviously you haven't read many problems, but submitted
several solutions to them. If you try reading the problem statement Say-100 for example and compare with the code you
submitted - you'll probably laugh yourself :)
Anyway thanks for stopping here to drop some encouraging words - it's appreciated.
Meanwhile I think this experience may be somehow useful to make problems more protected against robotized solvers.
I understand your concern about AI-generated solutions — it’s a real issue, and I get why it’s frustrating.
However, in my case, I did solve the problems myself. The inconsistencies you’re pointing out (style, input handling, etc.) come from writing many short solutions quickly and not enforcing a strict template, not from AI usage.
Regarding your specific example (Say-100): if my submission doesn’t match the problem properly, then that’s a mistake on my side. I’ve made incorrect submissions before, including using the wrong language or misunderstanding a task. That’s part of normal problem solving.
I’m happy to verify my work in a concrete way:
I can walk through any of my solutions step by step and explain the reasoning I can discuss alternative approaches and why I chose mine
I think that’s a more reliable way to judge than trying to infer authorship from coding style or occasional mistakes.
If you still think of me used AI stuff, please delete my account. Would be sad :(
I stand by my comments and observations.
Just to highlight one final and fun example: You cannot really misread the Tricky Printing problem, it even starts with a Brainfuck code example. Yet somehow you managed and submitted 7 different solution attempts in Python between 14:15 and 14:22 yesterday, and then switched over to a C/C++ attempt 3 minutes later. You again tried a BF problem - Summing Up - in Python at 15:29 but then provided a correct BF solution at 15:31. Clearly NOT learning from your mistake, you tried a third BF problem - Brain Fibo - 8 times bewteen 17:15 and 17:21. This time your unsuccessful solution attempts indicate use of Python, PHP and C/C++ - just not Brainfuck.
This will be my last post in this thread.
I also wanted to point out the same thing Mathias did: why did you try submitting several solutions to BF problems in any language but BF? In all these problems, it is clearly stated that the solution must be in BF (alright, maybe not in all of them, but they do have brainfuck tag assigned to them), you can't misread it two or three times in a row.
Also, the comments in your code explain obvious things, like input or output. I don't know why you felt the urge to write such comments, but LLMs love to insert them anywhere.
