2.10 Modular Design
Modular design is a fundamental concept in software engineering and computational thinking, focused on breaking down a system into smaller, manageable, and interchangeable parts, known as modules.
Example: In programming, functions or methods are modules that perform specific tasks. In Python, a function to calculate the area of a rectangle:
Example: OOP uses classes and objects to implement modular design.

Example: In web development, modular design can be applied through components and services.
Steps to Implement Modular Design
2.11 Algorithm Dry Run
The algorithm dry run means manual checking the execution of an algorithm by providing it specific set of inputs. This helps not only helps to verify algorithm's correctness but also to understand algorithm's behavior on certain inputs and conditions. By doing this, we are also able to identify logical errors, if any.
