Tracing Code Line by Line Builds Big-O Intuition
A developer explains complexity analysis by counting operations in simple loops, nested loops, and dictionary lookups. The method shows how to derive O(n), O(n²), and O(1) by tracing code examples. The approach aims to make algorithmic complexity intuitive for learners.

A practical tutorial, but it covers basics already well-documented elsewhere; its value is in the hands-on tracing method.
