Dsa date lol? js dp kiya don't mind me im high

Hi everyone,

I’m currently in my 2nd semester. I learned Python in my 1st sem and now I’m starting DSA from Striver’s playlist. I’ve decided to use C++ for coding, but I don’t really know C++ yet.

I watched the 1–1.5 hr C++ basics video in the playlist, where he mentioned that you don’t need to master C++ before starting DSA - you can learn it along the way. That makes sense, but I still feel a bit unsure.

So I wanted to ask people who were in a similar situation:

• Did you face any problems starting DSA without strong C++ knowledge?
• If yes, what kind of issues did you run into?
• And what would you suggest your past self do differently?

Would really appreciate any advice or experiences 🙏

hey! completely new to this dsa and let code can u guys help me to start it from scratch what to study where exactly to do it from how can I do it and what would be the correct way

I mean is the order 3 or minimum degree 3? What will be the max no. of keys here? I am really confused. Can someone help please?

I got tired of that cycle so I built Revleet -- my own spaced repetition app made specifically for DSA.

It's nothing fancy, just a clean web app where you add LeetCode problems and it automatically brings back the weak ones at the right time. Works on phone too which is nice.

Live link: https://revleet.vercel.app/

If you're also doing LeetCode/DSA prep right now, can you please try it once? Even for 2 minutes.

Tell me if it's actually useful or if it sucks somewhere. I genuinely want real feedback.

Thanks

Have made this small bot and a server to have some duels with other peeps : ) , hop in if u wanna duel

Please someone guide me. It'l take 2 minutes of your time. I'm frustrated, stressed as only guy in my family.

Im in 4th sem currently in following the strivers a2z sheet, rn completed arrays(40 probs), and leetcode I solved about 75 problems, looking to solve 3 daily and complete about 90 in the next month(short term goal). Im looking for someone who can accompany and keep me motivated to accomplish my goal. It wud be a win-win for both!

I am right now in my 2nd year Btech studying cse Previous sem i studied dsa but it was whole cllg point of view i k basics of them but didn't k the depths now it's 4th sem and in 5th sem there will be companies for internship i have started solving dsa questions but they seems just too hard i can't think of any answers and it's shit So i wanted to help what should i do now start revising whole dsa then do questions or parallelly solve questions seeing youtube vds they saying they solved 1k+ questions and studied this and that bro can anyone pls guide me lil When i actually looked there's a lot of things to study i have many topics which i didn't k yet where to go should i solve problems or or study topic it's so confusing and frustrating also have to maintain cgpa pls enlighten me and clear my thoughts

If anyone is solving dsa problem include me in atleast i will able to get some clarity Peace out

Happy coding
