📝 Program Descriptions

Special Number Concepts

Neon Number: A number whose sum of digits of its square equals the number itself.

• Example: 9 → 9² = 81 → 8 + 1 = 9 ✓

Spy Number: A number where the sum of all digits equals the product of all digits.

• Example: 1412 → Sum(1+4+1+2) = 8, Product(1×4×1×2) = 8 ✓

Palindrome Number: A number that reads the same forwards and backwards.

• Example: 121, 1331, 12321

Decision Making Concepts

Even or Odd: Determines if a number is even (divisible by 2) or odd.

• Example: 4 is even, 7 is odd

Leap Year: A year is a leap year if divisible by 4, but not every year divisible by 100, except if also divisible by 400.

• Example: 2000 and 2020 are leap years, 1900 is not

Positive, Negative, or Zero: Classifies a number as positive (>0), negative (<0), or zero (=0).

• Example: -5 is negative, 3 is positive, 0 is neither

Largest of Three: Finds the largest number among three given numbers.

• Example: Among 3, 7, and 5, the largest is 7

Grade Calculation: Assigns a grade based on marks using if-elif-else conditions.

• Example: 85 marks → Grade A, 70 marks → Grade B

Contribution Guidelines

• Follow Python naming conventions (PEP 8)
• Add comments explaining the logic
• Include example input/output in comments
• Test your code before submitting
• Update the README if adding new programs

📋 Code Style

All programs in this repository follow these conventions:

• Naming: Descriptive variable names (camelCase or snake_case)
• Comments: Triple-quoted docstrings for problem statements
• Input: Clear prompts for user input
• Output: Descriptive output messages
• Structure: Simple, readable code suitable for beginners

🐛 Known Issues

• Some programs reference "Java" in comments but are Python implementations
• The Operators/README.md file also references Java instead of Python

🔮 Future Enhancements

• Add more advanced programs (loops, functions, classes)
• Include unit tests for each program
• Add error handling and input validation
• Create separate directories for different topics
• Add more complex algorithms and data structures
