LLD Data Structures in Design Context: Why Some Problems Need Prefix Matching In

<blockquote> <p>"Learning data structures teaches you how to write efficient programs. Learning Low-Level Design teaches you why those same data structures quietly become the

<blockquote> <p>"The best software engineers don't recognize Queues by memorizing examples. They recognize the behavior that makes a Queue the right design choice."</p>

<blockquote> <p>"Not every software problem is about finding one object. Sometimes the real challenge is understanding how multiple objects are connected."</p> </blockquote> <p>So

<p>Low-Level Design is not about writing classes or memorizing patterns.</p> <p>It is about a fundamental shift in thinking:</p> <blockquote> <p>Designing systems as a collection
