What The Actual Heck is DSA? (Not Much Nerdy Jargon, Just Chill) Imagine this: You’re cooking. You’ve got ingredients (data). You need containers (bowls, pans) to hold them = Data Structures . Then you need recipes (steps to cook) = Algorithms . That’s it. DSA = containers + recipes. Why it matters? Slow app = bad DSA choice . Fast app = good DSA choice .
