**Composition**: Build complex classes by combining simpler ones. - **SOLID Principles**: Follow best practices in OOP to create maintainable and scalable code. #### **Recursion** - **Base Case**: Always define a clear base case to prevent infinite recursion. - **Smaller Problems**: Break down the problem into smaller instances of the same problem. - **Execution Flow**: Trace the function calls to understand how the recursion unfolds. - **Avoid Redundancy**: Use memoization to avoid recalculating results for the same input. - **Tail Recursion**: Refactor to tail recursion if supported, to optimize space complexity. --- ### **Weekly Reflection** - Spend 30-60 minutes at the end of each week reviewing your progress. - Write down key lessons, challenges faced, and areas needing further review. -

Understanding the Problem - **Clear Requirements**: FizzBuzz teaches the importance of fully understanding the problem before coding. - Example: Knowing exactly when to print "Fizz", "Buzz", and "FizzBuzz". - **Identifying Edge Cases**: Consider all possible inputs and outputs. - Example: Handling the start and end of the sequence, potential zero or negative inputs. ## 2. Start Simple, Then Optimize - **Naive Solution First**: Begin with the most straightforward implementation. - Example: Using separate if statements for each condition. - **Incremental Improvements**: Refine the solution step by step. - Example: Combining conditions to reduce redundant checks. ## 3. Pattern Recognition - **Identifying Repetition**: Recognize recurring elements in the problem. - Example: The cyclic nature of multiples of 3 and 5. - **Generalizing the Solution**: Create a solution that can handle similar patterns. - Example: Using modulo operations for divisibility checks. ## 4. Efficiency Considerations - **Time Complexity**: Analyze how the solution scales with input size. - Example: Ensuring O(n) time complexity for n numbers. - **Space Complexity**: Consider memory usage. - Example: Deciding between storing results or printing directly. ## 5. Code Readability vs. Cleverness - **Clear vs. Concise**: Balance between easy-to-read code and clever one-liners. - Example: Comparing a straightforward if-else structure with a more compact list comprehension. - **Self-Documenting Code**: Write code that explains itself. - Example: Using meaningful variable names like `is_divisible_by_three`. ## 6. Extensibility and Maintainability - **Parameterization**: Make the solution flexible for future changes. - Example: Allowing custom ranges or divisibility rules. - **Modular Design**: Separate concerns for easier maintenance. - Example: Creating separate functions for divisibility checks and output generation. ## 7. Testing and Validation - **Edge Case Testing**: Ensure the solution works for all scenarios. - Example: Testing with numbers like 0, 1, 3, 5, 15, and 100. - **Unit Testing**: Write tests to verify each component of the solution. - Example: Testing the "Fizz", "Buzz", and "FizzBuzz" conditions separately. ## 8. Performance Optimization - **Minimize Operations**: Reduce unnecessary computations. - Example: Checking for divisibility by 15 before 3 and 5 separately. - **Appropriate Data Structures**: Choose the right tools for the job. - Example: Using a dictionary for mapping numbers to words for more complex rules. ## 9. Scalability and Future-Proofing - **Handling Large Inputs**: Consider how the solution would work with a much larger range. - Example: Using generators for memory efficiency with large ranges. - **Adaptability**: Design the solution to easily accommodate new requirements. - Example: Structuring the code to easily add new divisibility rules. ## 10. Code Reusability - **Generic Solutions**: Create solutions that can be applied to similar problems. - Example: Designing a function that can handle any set of divisibility rules and outputs. - **DRY Principle**: Don't Repeat Yourself – identify and extract common logic. - Example: Creating a single function to check divisibility and return appropriate strings. By applying these strategies, programmers can approach not just FizzBuzz, but a wide array of coding challenges with a structured and effective methodology. These principles foster the development of efficient, maintainable, and scalable solutions.
