Method Decomposition & Clean Code
Break problems into small, well-named methods. Reduce duplication, prefer pure helpers, and keep parameter lists simple.
Why decompose methods?
Why decompose? Small methods are easier to read, test, and reuse. They highlight intent and hide detail so your main flow reads like a story.
Single responsibility
One purpose per method. If a method both calculates and prints, split it. Keep bodies short (roughly 5–15 lines) and names as verbs.
