Codeforces community (especially : wuhudsm, MikeMirzayanov) please look into this:

This user ckuhn222 seems suspicious to me by his/her shady problem submission's.

Firstly this user has loads of past skip submissions. I don't understand why can't codeforces make their rating 0 again if they get a skip or ban them.

Secondly today, Just after submitting A in div 1 in c++, they submit F1 in a minute in python (which i don't even think LGM'S can do) but it goes for Idleness limit exceeded on pretest 1 and then after 6 mins submits problem E which again fails.

This seems like they were just trying their best to copy paste solutions from various sources which eventually has passed in past leading them to reach master from newbie in span of 5 months.

I won't explain alot, you can kindly have a look at their profile.

If i am wrong I will delete this post & sorry ckuhn222 if i am wrong.

I have used chatgpt to frame my idea to look formal

Today, it’s super easy to create and work with arrays. Just declare and use. But I was thinking — in the past, memory was expensive, and even a simple array was a big deal. Now imagine the future...

What if we have a 2D array where each cell is like a tiny intelligent unit — able to communicate with its neighbors and make decisions? Almost like every grid cell being a mini GPT or agent.

So instead of writing pathfinding algorithms like BFS or Dijkstra centrally, the grid itself would solve it. Cells could pass messages, saying “I can reach the goal from here” or “I’m blocked” etc. Eventually, the path could be stitched automatically because each cell knows something local and shares it. Kinda like how ants communicate using pheromones or how neurons fire signals.

It feels like a wild blend of distributed systems, cellular automata, and AI. But the more I think about it, the more it feels like a direction computing could go in — especially with how edge AI and neuromorphic stuff is evolving.

I know it’s not useful today, but I’m curious — what do you think about this kind of direction? Has anything similar already been tried or theorized?

Thank you

Hi Radewoosh, please bring back Blogewoosh :). They were always fun to read and offered something new and interesting each time — even if I didn’t fully understand everything, I still enjoyed them a lot

Hello community, I really want to Study About Data structures in depth because I come from a non-cs background & was never taught about it in class.

Which is the best book to study Data Structures & Algorithms in depth. If Not a Book, any website which has a very detailed content on DSA Just like How MIT has on machine learning ( sure they have for DSA aswell)

Thank-you for your time

Hi,

If you enjoy or are interested in watching your favourite competitive programmers solve problems, here are some participants who record their contest sessions and share them after the contest concludes.

I have provided the user and link to their channel below:

Sorry If I missed out someone

Enjoy :)

This blog is just an appreciation post and a heartfelt thank you to Shayan. Whatever rating I have today is because of him. I started with zero knowledge of programming and used to watch his streams to learn new topics like arrays, strings, math, greedy algorithms, binary search, etc.

I was especially afraid of binary search and math, but Shayan motivated me to keep moving forward without fear. There were times when I felt discouraged, stuck on certain concepts that seemed impossible to grasp. However, his guidance and encouragement helped me push through those struggles.

Thank you, Shayan! You inspire people like me—those who are new to programming and hesitant to compete due to self-doubt and lack of confidence. Your support means a lot!

I will keep moving ahead and try my best to improve everyday.
