I'm an engineering student eager to learn Data Structures and Algorithms for job placements, but I'm feeling completely lost. I mean, I don't even know where to begin! I'm stuck on a few key points: what topics I should start with, the order in which to tackle them, the best resources for learning, how much time I should dedicate daily, and the right way to practice without feeling overwhelmed. When I check out resources like YouTube or coding platforms, the options seem endless, and I often end up just confused rather than making progress. I even find basic problems challenging since I don't have a strong foundation in problem solving yet. If you were starting from square one again, how would you approach learning DSA, structure your study plan, and consistently practice without getting overwhelmed? I'm more than willing to put in the effort; I just need some clear guidance and resources.

It really depends on your current coding skills. If you’ve taken a course in data structures and algorithms before, that's a good start. A popular method to follow is the Neetcode 150 list, which is a series of problems that cover key topics often asked in interviews. I recommend checking out the crash course titled 'Algorithms and Data Structures for Beginners.' This approach breaks down problems into manageable patterns like arrays, linked lists, sorting, trees, and more. Focus on one pattern at a time and practice—it will take some time to master all these, but free resources are available if you don’t want to spend money on books or courses.
Consider picking up a textbook, like 'Introduction to Algorithms' by Cormen. It's an excellent read—just be ready to do the exercises too. It covers a lot of material that can really boost your understanding.
Isn't that book super long? Like over 1300 pages? You really think I should tackle that?
Just start with GeeksforGeeks! It has practice problems for beginners, and whenever you're stuck, there’s often a related article that can help you understand the concept better. It’s great if you’re leaning towards competitive programming too!
True! The info is solid, but I have a hard time remembering what I practice later.
Don’t worry; DSA doesn’t require heavy math. What you really need is logical thinking, basic math skills (like addition and multiplication), and a knack for recognizing patterns. Advanced math only comes into play for more complex topics like competitive programming. For job interviews, strong logic and lots of practice are what really count! I can break down how much math you'll actually need if you're interested.
Can you share your study plan? Like should I focus on arrays for a week or mix things up?
Can you share what pattern you've been working on? I'm curious!
