Unlike an array, the elements are not contiguous in memory, so you cannot jump to index <code>k</code> in constant time. That single difference drives every trade-off below.</p> <h2 id="why-linked-lists-matter">Why Linked Lists Matter<a class="header-anchor" href="#why-linked-lists-matter" aria-label="Permalink to this heading">#</a></h2> <p>Linked lists show up in interviews less for their raw usefulness and more because they force you to reason about pointers carefully. Reversing a list, detecting a cycle, or merging two sorted lists all reward candidates who can track &ldquo;what points to what&rdquo; without a diagram. They also underpin real structures: hash-table buckets, LRU caches, and adjacency lists all lean on linked-list mechanics.</p>
