Feature: Robust Prime Number Checker Implementation

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 comprehensive prime number checking function with robust error handling and efficient algorithmic approach.

Implementation Details

• Function: is_prime(number) in src/prime_checker.py
• Key Features:
  • Efficiently checks primality with O(√n) time complexity
  • Handles various input scenarios
  • Provides clear type checking and error handling

Acceptance Criteria Met

1. ✅ Correctly identifies prime and non-prime numbers
2. ✅ Handles edge cases (0, 1, negative numbers)
3. ✅ Raises appropriate type errors for invalid inputs
4. ✅ Efficient implementation checking only up to square root

Testing Approach

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

Algorithm Explanation

• Uses trial division method
• Checks divisibility only up to square root of the number
• Provides early termination for non-prime numbers
• O(√n) time complexity for primality testing

Potential Future Improvements

• Consider adding support for very large numbers
• Implement more advanced primality testing algorithms if needed

Changes Made

• Implemented is_prime() function with efficient primality checking
• Added comprehensive type checking
• Created test suite to validate prime number detection
• Handled edge cases for input validation

Tests

• Verify prime number detection for positive integers
• Check handling of edge cases (0, 1, negative numbers)
• Validate type checking and error handling
• Ensure performance for various input sizes
