# Problem-Solving Strategies Exemplified by FizzBuzz

## 1. 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.
