Implement Robust 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

• Added is_prime() function in src/prime_checker.py
• Implemented comprehensive primality testing algorithm
• Created extensive test suite in tests/test_prime_checker.py

Implementation Details

• Algorithm:
  • Efficient primality check using square root optimization
  • Checks divisibility up to the square root of the input number
  • Handles computational complexity with O(√n) time complexity

Input Validation

• Validates input is an integer
• Handles edge cases:
  • Returns False for numbers less than 2
  • Raises TypeError for non-integer inputs
  • Correctly processes negative numbers

Testing Approach

• Comprehensive test coverage including:
  1. Prime number verification
  2. Non-prime number identification
  3. Large number testing
  4. Negative number handling
  5. Invalid input type checking

Acceptance Criteria

• ✅ Correctly identifies prime numbers
• ✅ Handles edge cases and input validation
• ✅ Performs efficiently for various input ranges
• ✅ Provides clear error handling

Performance Considerations

• Optimized algorithm reduces computational complexity
• Early return for non-prime numbers
• Minimal memory usage

Notes

• Function returns False for 0 and 1
• Supports integer inputs only
• Designed for clean, readable, and maintainable code

Changes Made

• Implemented is_prime() function with primality testing
• Added comprehensive input validation
• Created efficient primality checking algorithm
• Developed extensive test suite covering multiple scenarios

Tests

• Verify identification of prime numbers
• Confirm non-prime number detection
• Test large prime and non-prime numbers
• Validate input type handling
• Check negative number processing
