I'm a final-year student who has been delving into Data Structures and Algorithms (DSA) for the past three years, but I'm still having a tough time mastering it. While I understand the theory of DSA really well, translating that knowledge into coding is where I'm struggling. I can follow tutorials and replicate the code for a bit, feeling confident at first, but when I try to write it from memory weeks later, everything goes blank. It's frustrating!
I often realize I've made simple mistakes in my code—like using the wrong loop boundaries or starting points—and I can't find those bugs because I haven't learned to dry run my code properly. When I try to debug, I just get stuck.
I'm not looking for more tutorials or roadmaps, I really want to know what the best approach to learning DSA is. Any guidance would be much appreciated!

I suggest leaving behind the tutorials for now. Try tackling problems on platforms like LeetCode on your own. Pick one topic, like hashmaps, and work through it. If you're stuck, you can peek at solutions, but focus on understanding the reasoning behind each step! Remember, even the pros started where you are now.
You mentioned struggling with dry running your code. It's about visualizing how your code operates step by step, almost like acting it out in your mind. This can help you identify where things go wrong. Practice this technique, and it'll get easier!
That's a solid point! It's all about understanding the flow. Try writing out what each part should do before coding.
Honestly, the best approach is immersion in the algorithms themselves. Start with basics, ensure you can implement them without references, then move to more complex variations. Don't shy away from making mistakes; instead, learn from them! Keep practicing daily if you can—consistency is key!
It sounds like you're struggling with both remembering the algorithms and truly understanding them. The key isn't to memorize every algorithm, but to grasp why they're structured that way. Look up a specific algorithm when you need it, study the pseudocode, and then create your own implementation based on that. Give yourself a chance to learn through trial and error—it's part of the process!
Exactly! It's all about understanding the concepts instead of rote memorization. It'll make a big difference in how you code.
Have you thought about using a debugger in your coding sessions? It can really help you track down issues more easily and understand what's happening in your code.
Thanks for the suggestion! I think I need to shift my focus to problem-solving rather than just watching others.
