Implement Efficient Prime Number Checker Function

Description

Task

Implement Prime Number Checker

Acceptance Criteria

• Function should return boolean indicating if number is prime
• Implement efficient primality test
• Handle edge cases (negative numbers, 0, 1)
• Include unit tests for various cases

Summary of Work

Prime Number Checker Implementation

Changes Made

• Implemented is_prime() function in src/prime_checker.py
• Added comprehensive prime number detection logic
• Developed robust input validation and error handling

Implementation Details

• Created an efficient prime number checking algorithm
• O(√n) time complexity for primality testing
• Handles various input scenarios:
  • Positive and negative integers
  • Zero and one
  • Large prime and non-prime numbers
  • Invalid input types

Key Features

• Type checking to ensure integer input
• Early elimination of non-prime numbers
• Optimized divisor checking up to square root
• Special handling for edge cases (2, even numbers)

Testing Approach

• Comprehensive test suite covering:
  • Known prime numbers
  • Known non-prime numbers
  • Large prime and non-prime numbers
  • Negative numbers
  • Invalid input type handling

Test Results

• All 6 test cases passed successfully
• 100% test coverage for prime number detection
• Robust error handling verified

Acceptance Criteria Met

• Accurately identifies prime numbers
• Handles edge cases and invalid inputs
• Efficient implementation with O(√n) complexity
• Comprehensive error handling
• Fully tested and validated

Notes

• Future optimizations could include more advanced primality testing for extremely large numbers
• Current implementation is suitable for most practical use cases

Changes Made

• Implemented is_prime() function in src/prime_checker.py
• Added comprehensive input validation
• Created efficient primality testing algorithm
• Ensured coverage of all test cases in test_prime_checker.py

Tests

• Verify prime number detection for positive integers
• Check handling of edge cases (0, 1, negative numbers)
• Test performance with large prime and non-prime numbers
• Validate type checking and error handling
