UUtkarsh Gaur·Jan 12Beyond Big-O: Rethinking How We Measure Algorithms in Real SystemsBig-O notation has been drilled into us since our first data structures class. O(1) good.O(n) acceptable.O(n log n) fine.O(n²) bad. We memorize it for interviews, use it to compare algorithms, and treat it as the final word on performance. But once y...3 min read·hexplain.hashnode.dev

JJoel Tikoo·Dec 2, 2025Why Big-O Actually Matters (Even If You Think You'll Never Use It)If you’re anything like me, the first time someone explained Big-O notation, it felt like they were trying to measure my code using math from another galaxy. “This algorithm is O(n log n).”“Bro… I just want my code to work.” Same energy. But the deep...3 min read·joelcodes.hashnode.dev
