Which term describes condensing a codebase into a shorter representation while retaining its core behavior?

• A. Summarizing code
• B. Refactoring
• C. Obfuscation
• D. Documentation

Answer: (A)

Refactoring focuses on changing the internal structure of code to be cleaner and often shorter, while keeping its observable behavior the same. This makes it the best fit for condensing a codebase into a shorter representation without altering what the code does. You might extract repeated blocks into functions, rename variables for clarity, and simplify complex conditionals. All of these changes improve maintainability and readability without changing how the program behaves from a user’s perspective. Other terms don’t fit as well: summarizing code isn’t a standard practice term for modifying code itself, obfuscation aims to hide intent or make code harder to understand (not primarily to shorten and preserve behavior for readability), and documentation explains code rather than altering its implementation.
