Big O Notation - What Every Developer Must Know

Big O Notation is more than just a theoretical concept; it is the absolute yardstick for evaluating code quality and system reliability. Are you still judging your program's performance based on mere "intuition" or "execution time"? In this lecture, we dive deep into the foundations of Big O to help you bridge the gap between a beginner and a professional engineer. A program that runs fine with 100 records might trigger a system-wide collapse when scaled to a million. We will provide you with the mathematical "blueprint" to predict and prevent these failures before they happen.
