Need dsa partner

• Upvotes

Like i already did leetcode and while solving questions i really miss a companion so i wanna have a partner who will be like also solving questions with me

Like basically same questions

So that we can be in the same pace

And not like too much just doing dsa

As i dont want someone who is just dsa dsa

I want someone who does leetcode like maybe 1 or 2 problem daily & maybe post on LinkedIn for daily updates

But also like learn skills and other things

Somethings that i will prefer more

And also like we can be frnds like not only studies but like most of the time only studies actually so that we cant diverse ourselves from distractions and other things

Looking for a serious AI/ML study partner for the next 3 months—London or remote

3 Upvotes

I’m based in London and looking for one committed study partner to work towards data science or ML job applications over the next three months.

My focus is data science, machine learning, neural networks, and DSA, then computer vision, transformers, and RAG as we progress. We’ll prioritise topics based on our gaps and build projects alongside interview preparation.

I’m aiming for 10+ hours on days I’m free, around university and work. I want someone equally ambitious who will show up consistently, challenge my thinking, and expect the same from me.

The plan:

  • Daily goals and honest progress updates.
  • Daily discussions about problems, bugs, and concepts we’re stuck on.
  • Code reviews, problem-solving sessions, and weekly project demos.
  • Job applications and interview practice throughout.

London would be ideal for occasional meetups, but other countries are welcome if our schedules overlap.

If interested, DM me your current level, time zone, availability, and target role. Let’s agree on a realistic schedule and get started.

Mock Interview Practice Group

15 Upvotes

Hi! I (27F) and my friend (23M) are looking to connect with people who are interested in practising mock interviews together.

We’ve been practising for the past month, focusing on DSA, problem-solving, and technical interview preparation. We’d love to connect with people who have industry work experience and can guide us with their insights, interview experiences, and tips on how to approach real-world technical interviews.

If you’re also preparing for interviews or have experience in the industry and would be willing to help us improve, we’d love to connect! We’re also happy to practise together and help each other grow.

Feel free to comment your discord.

11 of us so far—building a tech learning group from London

17 Upvotes

I’ve started a Discord group for people learning AI, machine learning, Python, and DSA. We’re sharing daily progress and planning one weekly session to work through problems and review what we’re building.

Our first challenge: each person brings one real problem they’d like to solve. Together, we’ll question the ideas, choose one, and build a working prototype—sharing the mistakes and results along the way.

If you want to learn, contribute, and build with others, comment or DM me for an invite.

What’s one problem you’d bring to the group?

How to make notes while learning DSA in C++?

1 Upvotes

I wanted to ask all my seniors who made DSA notes: first, did it help you? I am currently learning C++ from YouTube and practicing in VS Code, but I have a doubt regarding notes. I have watched some YouTube videos on how to make them, but I am getting a bit confused. I want to make handwritten notes. In one video, I saw that you should divide your notebook into different sections — one for arrays, another for the next topic, and so on — so that it is easy to revise later. However, I am confused about how much space to allocate to each topic, since I literally don't know anything about DSA yet. Please guide me. I really want to learn DSA and will give my 100% — I just need good guidance. By the way, I am currently watching the DSA series by Apna College. Till now I have only done the basics. (functions, if else, variable, etc.)

Hello..

I am a bca graduate with not much programming knowledge neither skills...

I am thinking to start dsa , but confused to choose language..

Many suggestions told java would be better...but I am thinking to go with python as I am also joining an ai/ml online course...

So it would be helpful for both..

Any suggestions...whether should I go with java or python??

I want to learn DSA and do Leetcode but I'm confused where to start

8 Upvotes

Currently in 1st year, I have completed basic c++, all the loops and c style arrays and stuff like that, now I'm confused how to proceed, I open up a leetcode problem and there is time and memory and all that stuff and I don't know how to deal with it, there is also the weird thing of class stuff that should be at the beginning of each question, I don't know where to learn all of this.

Can someone suggest where to learn all of this, because I couldn't find a proper series that teaches all of this. Also tell me what things I should learn before I start doing leetcode, I have already started learning STL, is there anything else I should learn?

Making DSA easier to learn in Telugu ❤️

6 Upvotes

I run Logic Over Syntax, a YouTube channel where I teach Data Structures and Algorithms (DSA) in Telugu, helping students understand problem-solving logic instead of just memorizing code.

We've already reached 20,000+ watch hours, and my goal is to make coding education more accessible to Telugu-speaking students.

Title: I added a free 8-week DSA roadmap for people struggling to stay consistent with LeetCode

5 Upvotes

One of the hardest parts of DSA prep isn’t solving problems. It’s figuring out what to practice every day and staying consistent.
So I just added a new 8-week DSA roadmap to FeatCode! 🚀
The goal is simple: Stop randomly grinding LeetCode and start following a structured plan.
FeatCode also includes:
✅ Structured DSA practice
✅ Blind 75 + interview-focused problems
✅ Free DSA assessment to identify weak areas
✅ Curated YouTube solutions from popular creators
✅ Progress tracking
✅ Python crash course
Everything is free. No paid subscription required.
🔗 https://featcode.dev
I’m actively improving the platform and would love some honest feedback.
For those preparing for SWE interviews: Would you follow an 8-week structured plan, or do you prefer solving problems at your own pace?
Would love to hear what actually works for you!

I understand DSA solutions, but struggle with unseen problems—any advice?

32 Upvotes

I work as a chef in London, and the long, physically exhausting shifts make finding energy to study difficult. Still, I’m learning DSA from books—my first time learning this way instead of YouTube.

I’ve covered two pointers, hashing, sliding windows, stacks, queues, and time and space complexity. I can understand and explain solutions I read, but struggle to find an approach and write code for unseen questions.

What practice routine would help me solve problems independently while balancing demanding chef shifts?
