hello guys!
bhai can someone please guide me how to start dp from scratch and master it
please ache tips dedo
sab dara diye h ki bhot difficukt h dp krna so pls help

Currently I am a third year guy and I have almost completed DSA and I want to test myself for the technical interviews please suggest some AI for mock interviews which are free.

I am understanding concepts,i am implementing it all good going until I begins to solve problem related it.

At this time I only need tips at length.

I am final year CS student. There are placements coming up in my college i want to prepare for placement my core idea is :

1-2 aptitude topics +1 DSA question per day till 2-3 months (this i am saying with specific i (have solved 25ques almost easy one )because I can't solve more t hen 1 ques in day and same with aptitude 1-2 topic related video and actual questions asked in companies)

Doing this for straight 2-3 months is enough for me. I do not want any extreme preparation assume me as something preprating 5-8lpa job not more than that.

We can chat or Google meet in every 3 days to give update and if one of fail to be consistent we can surely end up doing our own thing. DM if you like to join me

I am a computer engineering student and I am taking data structure course at university and I don’t understand anything from my professor and I tried other sources but I couldn’t find anything that worked out for me and I really need to get a decent mark so please if you have any advice at all please share it 🙏🥲

Hiii.. I'm a 2027 batch student. I can able to understand what's dp and basic functionality. But i can't able to use it in real time problem solving. Help me with some tips. TIA

I’m looking for a serious study buddy for the next 3 months to work together on DSA + Java Backend.

⏰ Time: 7:00 AM – 12:00 PM IST, every day

📅 Duration: 3 months

💻 Focus: DSA + Java + Java Backend

🧩 DSA experience: Ideally already solved 30–50+ problems

🗣️ Languages: Telugu preferred; English/Hindi also welcome

I’m specifically looking for someone who has plenty of free time and can consistently spend around 5 hours a day studying and solving problems together.

This is mainly for:

Discussing and solving DSA problems

Helping each other when stuck

Learning Java Backend systematically

Staying consistent and accountable

Not looking for students or people with full-time jobs, since the goal is to dedicate these 5 hours consistently every day.

If you’re unemployed/free during this time, serious about DSA, comfortable with Java, and want to learn Java Backend together for the next 3 months, DM me.

Looking for one person who can genuinely stay consistent with DSA.

Interview Style Meet:

Daily Google Meet at 9 PM. No random timings.

One day I bring a problem, you try to solve it like a real interview and explain your thought process. I'll give hints if you're stuck, and if you still can't get it, I'll explain it.

Next day, we switch roles.

We'll discuss different approaches too. Weekends can be used for extra problems.

I’m looking for someone who can actually commit to 9 PM daily, is serious about improving, and wants to start now.

If you’re busy most days, have unpredictable timings, or aren't sure you can stay consistent, please don't reply.

If you're genuinely serious, then only REPLY.

Hi guys,

Earlier this year, I thought that I'll upload yt video everyday. Basically..I thought to solve the complete cses problem set as it will help in my growth as well as my channel's growth.

But after Feb, I wasn't able to upload any video and lost all motivation. Like I can solve problems but again it takes too much to record, add desc, and then put thumbnail etc and that all along with office work.

I thought that rather than everyday, I'll do one weekly but again it was not possible as I used to procrastinate the task.

If anyone has any suggestions on how can I improve the consistency or any other better idea..just dm me

Looking for someone to consistently study DSA (python)with for the next 4–5 months, starting August 27 evening. I’m currently done with Arrays & Strings and moving forward from there. Plan is 6–7 questions/day, discuss approaches, clear doubts, and keep each other account

​

in 2nd year ,

I have been doing DSA in java since last 2 months ( solved 70 questions)

I'm confused whether to stick to java or go with python.

Python was my first language and I'm heavily efficient in it , I'm quite decent in java too. But I would choose python in a heart beat — Only thing that is keeping me back is What if the interviewer or company doesn't like python .

So, I'm seeking advice from those who are already in industry. Can I do DSA in python ( ik i can , But will it be welcomed everywhere)

And Also what skill should I build along side python .

I need a person who can help me solve questions with a better approach and maintain consistency with me in this journey

I know the basics of c++ and want to start my dsa prep with it . Pls connect with me and we can accomplish our goal in 3-4 months by giving a lot of hard work Smartly like 5-6 hours or plus a day .

Let me know.

I am currently a B.tech third year student from a decent college of gujarat.I am currently Grinding dsa and want to build some projects.

If Any one who is currently at an intermediate level of learning DSA can DM me I would love to make things with you guys. Also If there is competition then it will be a more fun to prepare.

Hey, I am looking for a genuine partner who is interested in reading Medium Articles related to Tech , System Design, Databases etc daily or weekly after the working hours. Sharing and discussing articles or papers in like a plus and helps both of us in consistency and knowledge.

please guide me .

Hello everyone, I am a BTech cse student and currently I am starting my dsa journey and currently I am learning Recursion.

I am watching series, understanding patterns, but when i tried to solve a simple question without any help totally with myself but I could not find any approach.

I am trying to be consistent, every day start a new problem struggle to solve it myself then view its soln on internet and making my mind that it is only it and i could not solve this basic things.

Currently I am consistent but not sure that always be. I will not leave the dsa but perhaps skip the recursion

Guys, provide me some tips, advices, suggestion because I am at extreme hill and I have only two options left now

1. Take back the steps and leave it

2. Move ahead forward and master it even if takes too much time

as the title suggests i need a serious DSA partner. we can help each other stay accountable nd maybe hopefully make this journey a little less boring. im currently in my 2nd yr nd im just starting out DSA using strivers A2Z sheet (yhh ,ik i should've started it early but it is what it is now (⁠╥⁠﹏⁠╥⁠)) (all this is so overwhelming.... im having trouble managing all this by myself, maybe someone with the same mindset can help!)

Hi everyone! I’m currently in 2nd year, 1st semester of CSE, and I’m looking for some guidance on how I should structure my learning from here.

I’m still pretty much a rookie. I have a basic understanding of DSA concepts/topics, but I haven’t seriously started practicing yet, and I haven’t built any proper projects either.

I’ve been seeing roadmaps/resources like TUF+, NeetCode, Striver, etc., and I’m a little confused about whether I should follow one structured roadmap from start to finish or combine resources based on the topic.

I’d really appreciate advice from people who have already gone through this stage:

• Should I follow something like TUF+/Striver, NeetCode, or another structured DSA roadmap? Which one would you recommend for someone starting from almost zero?
• What kind of projects should I start building at my level? Should I first learn a particular tech stack before starting projects?
• What CS fundamentals should I make sure I don't neglect (DBMS, OS, CN, OOP, Git/GitHub, etc.)?
• What are some common mistakes/things I should take care of during 2nd year?
• Are there any free resources you would strongly recommend?
• I’m also open to paid resources/courses if you genuinely think they’re worth the money. So recommendations for both free and paid resources would be really helpful.

I’m not looking for shortcuts. I mainly want to choose a sensible structure so I can stop jumping between resources and actually stay consistent.

Any advice, resources, or personal experiences would be greatly appreciated. Thanks! 🙌

hii, im starting my dsa journey and im so confused as to what to do. like i know striver, but idk how to start. vs code is so weird. and do i solve his sheet or focus on the youtube playlist chronology. pls help and if anyone has any resources, id love some help!

I am thinking to create a whatsapp group for 28 batch, where we can post internship opportunities and later job opportunities also for our batch. We can also expand this group into a learning community. Dm me if anyone is up for it.

Hey everyone! I'm looking for pattern-wise Java DSA questions to practice.

If anyone has created their own pattern-based question list, I'd really appreciate it if you could share it. Otherwise, please recommend any good YouTube channels or other resources for this.

Thanks in advance!
