Czy mogę uczyć się slangu z Reddita w SubRead?

Tak. Spokojny czytnik: otwórz wątek, zaznacz frazę, weź wyjaśnienie i zapisz jako fiszkę.

Czym jest Language Lab?

Krótkie pakiety (czas, hedging, slang, reakcje) jak się pisze na Reddicie — potem pytaj Iggy.

Czy nadaje się dla ESL / poziomu średniego?

Tak: prawdziwe posty i komentarze zamiast dialogów z podręcznika, z AI gdy ton lub slang jest niejasny.

Czy potrzebuję konta?

Możesz czytać bez. Zaloguj się, by zapisywać fiszki, ulubione, czat z Iggy i profil.

Best way to build strong DSA fundamentals?

Hi everyone,

I have around 4 years of experience as a backend Java developer, but most of my work has been building production applications. I never really focused on DSA, so my fundamentals are quite weak beyond the basics.

I want to get good at DSA, but I also want to build a strong foundation instead of memorizing patterns or solutions. I tried following the Striver A2Z sheet, but I found myself watching the solutions too quickly. A few days later, I couldn't remember the intuition or approach.

I'm considering starting with Abdul Bari's Data Structures & Algorithms in Java course on Udemy before moving on to LeetCode and interview preparation.

For those who have been in a similar situation:

Is Abdul Bari's course a good place to start?
Is there a better Java course that you'd recommend instead?
How did you go from weak DSA fundamentals to becoming good at problem solving?
Did you follow a specific roadmap or study strategy that worked well for you?

I'm not in a rush and I'm happy to spend a few months building the right foundation. I'd really appreciate hearing what worked for you.

Thanks!

have you tried not doing that? Anytime you feel the urge to check, just get up from your seat and walk around my dude/dudette.

Is Abdul Bari's course a good place to start?

Yes, but you don't really need to do a paid course. DSA is language agnostic, and with your experience, you should have no trouble implementing pseudocode. I'd just watch his YouTube lectures instead. I'd suggest the Udemy course if you were just coming off an intro to XYZ programming language since it'd give you more practice with a language, but that's not you.

Why would paid courses be necessary here? Just find something interesting and look it up on Wikipedia.. Try implementing Huffman coding or something

  That's a fair point. I know most of the information is available for free. I guess I'm looking for something more structured because I don't have strong DSA fundamentals. I tend to jump between topics or watch solutions too quickly, so having a well-organized course feels like it would keep me on track. Also, I know myself, and paying for a course gives me a bit more motivation to actually finish it instead of hopping between random YouTube videos and articles. Once I have the basics down, I'm completely happy to switch to implementing algorithms on my own and using free resources.

Seem to me that you are in a rush
