What Is Readability

That code is what happens when you tell a developer "we need to save space" but forget to mention "code readability" as a requirement. Single-letter variables, no comments, and recursive calls that would make even the Python interpreter question its life choices. The smirking girl in front of the disaster is all of us watching our colleagues defend their "optimized" code during code review while the codebase burns in the background. Remember kids, the next person to read your code might know where you live.
