What is abstraction in the context of computer science?
- The process of breaking down a complex problem into smaller parts
- Ignoring irrelevant details and focusing on essential aspects of a problem
- Combining multiple algorithms to solve a problem
- Creating a physical representation of a problem
How does abstraction contribute to code maintenance and readability?
- It makes the code longer and more complex
- It introduces unnecessary details into the code
- It simplifies the code by hiding complex implementation details
- It limits the scalability of the code
