The answer
It means taking a confusing mathematical formula (like 2*row - 1), calculating it, and storing it in a descriptive variable (like maxStars) before the loop starts.

More FAQs in Optimizing Pattern Code Readability
Because patterns naturally require dense math and nested loops. If you don't write it cleanly, the code becomes impossible to debug or explain to an interviewer.
Variables like 'i' and 'j' carry no semantic meaning. Using 'row' and 'space' explicitly documents the loop's geometric purpose.
Yes, especially for composite patterns. Creating functions like printStars(int amount) drastically reduces code duplication and makes the main loop highly readable.
