Need Guidance

I am in SY of my btech and haven't started DSA yet and I am not understanding from where I should start ?

Like I completely wasted my FY and didn't built any skills (btw I have to travel daily for 4-5 hrs for college)

I had C language and Java (OOPS) for my first and second sem respectively

So anyone tell me from where I should start and whose playlist I should refer ?

STRIVER A2Z DSA

What is the BEST WAY TO LEARN FROM THIS PLAYLIST???

like should we make notes for all lectures? Or should we jot down only important points? Or should we just listen and understand?

(Extra tips will be acknowledged :)

Feeling lost in DSA before placements. Looking for a roadmap that actually works

Hi everyone,

I'm an S7 Computer Science student, and I have my Infosys placement in about a month.

I'm comfortable with Python (syntax, lists, dictionaries, functions, etc.), but my biggest weakness is DSA problem solving and pattern recognition.

I've been practicing for around 20 days, but when I see a new or indirect problem—even an Easy one sometimes—I go completely blank. I don't know how to start or how to identify which approach or pattern to use.

I can understand solutions after seeing them, and if I revisit similar problems later, I can often solve them. But with new problems, I struggle to connect the dots.

For those who were once in a similar situation and improved:

How did you build your problem-solving skills?

How did you learn to recognize patterns?

If you had only one month before placements, what would you focus on?

I'm willing to work hard—I just want to make sure I'm practicing the right way.

Thanks in advance!

Need Help, i am a dumb student

I admit I am a slow learner, and have to try again and again to learn something. I genuinely want to have good internship, so need to be good at solving questions of data structures. Please suggest some free resources where it is a proper structure of questions. I promise I will follow it religiously. In leetcode, I felt questions were just randomly thrown. Please help

Confused about where to start DSA for placements. Need a clear roadmap.

​

I'm getting overwhelmed by all the DSA resources out there and don't know where to start.

My goal is to get really good at DSA for placements. I know basic C and I've studied DSA in college, but only enough to pass exams. I know the very basics of linked lists, stacks, queues, etc., but it's been around 6 months since I last touched DSA, so I've forgotten quite a bit.

My confusion is:

Should I relearn DSA from scratch first or jump straight into LeetCode?

Is solving problems the best way to learn, or should I finish theory first?(ik problems r better but idk much dsa to start solving good problems)

Which YouTube playlist would you recommend? There are so many (Striver, Abdul Bari, Kunal Kushwaha, etc.) that I'm stuck in tutorial hell before even starting.

I prefer solving problems over watching long videos, so I'm looking for a concise playlist that covers the theory quickly and lets me start grinding LeetCode as soon as possible.

If you were starting again with my current knowledge, what roadmap would you follow?

Thanks!

Which DSA sheet to follow for covering all topics in 2 months time

Hello all!

I am preparing full time now. I can give almost all my day to dsa. So I think 2 months should be enough for this. Which sheet to follow?

Actually I was inclined towards striver A2Z sheet but now it requires to purchase a plan.

can you guys provide some free alternative? Is neetcode 150 enough for cracking good product based companies? Love babbar or shraddha from apna college?

What's is the best way to solve graph and dp problems

Hi everyone,

I've been practicing Graphs and Dynamic Programming for the last six months, but the truth is that I still can't solve a single new problem completely on my own.

Everyone says that DSA is all about recognizing patterns, but I feel like I'm not actually learning those patterns. I've watched many tutorials and solved the questions explained in them. However, whenever I face a different problem that's based on the same pattern, I still can't figure out the approach myself.

This makes me wonder: am I just memorizing solutions instead of learning how to think?

Whenever I look at the solution, I understand the logic and why it works. But what's the point if I can only solve the problem after seeing the answer?

My usual process is to struggle with a problem for about an hour. If I still can't make progress, I use an AI tool to understand the solution. The problem is that this happens with almost every question. It makes me wonder how long I'll have to depend on AI before I can solve problems independently.

I'm feeling really frustrated. Has anyone been through the same situation? What strategy helped you develop problem-solving skills so that you could eventually solve questions on your own instead of relying on solutions?

Best Resource to Master Graph and DP

I'm stuck on Graphs and Dynamic Programming. I understand the basics, but I struggle to solve medium and hard problems on my own.

Can you recommend the best resources, playlists, or problem lists that helped you master these topics? Any structured roadmap would be appreciated.
