I'm pretty new to data structures and algorithms (DSA) and I'm not sure why they're important. What exactly should I focus on learning? How much time do I need to invest, and will it really make a difference in my programming career? I'm struggling to find the motivation to start. Can someone explain if this is really worth it and how to get going?

Getting a grip on big O notation will definitely enhance your programming skills. It's not just about writing code; it's crucial to understand how long your code takes to run and how much memory it uses. Once you start comparing different solutions, you'll see why one is more effective than another, especially with larger inputs. DSA might sound daunting, but with just a few days of study, you can pick up the basics. It could even turn into a fun challenge once you get the hang of it. Try websites like Codewars for practice, and check out free resources like CS50's DSA videos or the Scrimba DSA course to get started!
Learning DSA enhances your problem-solving skills, teaching you how to think critically, not just how to code. You don't need to be an expert from the start—begin with fundamental concepts like arrays and strings. Dedicating an hour a day can be a great way to get into it. This knowledge will be beneficial for interviews, and every project you'll encounter. Just focus on starting small and being consistent, and you'll gradually find that spark of motivation!
Should I watch YouTube tutorials or jump straight into solving questions? I have a basic understanding of C++ and have studied linked lists, stacks, and graphs in college. What do you recommend?
