Building Intuition for Big-O by Tracing Code Line by Line
Complexity analysis becomes intuitive when you count operations by actually tracing through examples. Practice output prediction problems at PyCodeIt.
Most Big-O explanations are abstract. This one is not.
Complexity analysis is just counting operations. Tracing code to count operations is the most reliable way to build genuine intuition for why an algorithm has the complexity it has.
