When the problem has the right structure, that shortsighted strategy still lands on the global optimum, and it does so far faster than exhaustive search. The catch is that greedy is only correct for some problems, and proving which is the real skill.</p> <h2 id="why-greedy-matters">Why Greedy Matters<a class="header-anchor" href="#why-greedy-matters" aria-label="Permalink to this heading">#</a></h2> <p>Greedy algorithms are the fastest tool in the box when they apply: usually O(n log n) dominated by a sort, sometimes O(n). Activity selection, Huffman coding, Dijkstra&rsquo;s and Prim&rsquo;s algorithms, interval scheduling, and many coin and jump problems are greedy. Interviewers use greedy questions to see whether you can justify a strategy rather than just code one, because the wrong greedy choice fails silently on an edge case.</p>
