Implement Robust Prime Number Checker with Comprehensive Testing

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

Overview

This pull request implements a robust prime number checker function in Python, providing an efficient and comprehensive solution for determining whether a given number is prime.

Changes Made

• Implemented is_prime() function in src/prime_checker.py
• Added comprehensive test coverage in tests/test_prime_checker.py

Implementation Details

Prime Number Checking Algorithm

• Uses an optimized approach to check primality
• Checks divisibility only up to the square root of the number
• Handles time and space complexity efficiently
• O(√n) time complexity for primality testing

Key Features

• Input validation for integers
• Handles edge cases:
  • Returns False for numbers less than 2
  • Raises TypeError for non-integer inputs
  • Correctly identifies prime and non-prime numbers

Testing Approach

• Implemented test cases covering:
  1. Small prime numbers
  2. Small non-prime numbers
  3. Large prime numbers
  4. Large non-prime numbers
  5. Negative numbers
  6. Invalid input types

Test Results

• All 6 test cases passed successfully
• 100% test coverage for prime number checking functionality

Acceptance Criteria Met

• ✅ Efficient prime number checking algorithm
• ✅ Comprehensive error handling
• ✅ Thorough test coverage
• ✅ Clear and documented implementation

Notes

• The implementation provides a balance between performance and readability
• Future optimizations could include more advanced primality testing for extremely large numbers

Changes Made

• Implemented is_prime() function in src/prime_checker.py
• Added comprehensive test cases in tests/test_prime_checker.py
• Handled edge cases for input validation
• Implemented efficient primality testing algorithm

Tests

• Verify prime number detection for small primes
• Confirm non-prime number identification
• Test large prime and non-prime numbers
• Validate handling of edge cases
• Check input type validation
