Enhance String Reversal Utility with Robust Implementation and Comprehensive Testing

Description

Summary of Work

This pull request introduces a robust and flexible string reversal utility across multiple implementation approaches, providing enhanced functionality and comprehensive test coverage.

Purpose

Develop a versatile string reversal solution that:

• Supports various input scenarios
• Provides consistent error handling
• Demonstrates multiple implementation techniques
• Ensures high-quality, reliable string manipulation

Key Improvements

• Multiple implementation strategies for string reversal
• Comprehensive input validation
• Support for diverse string types (ASCII, Unicode, special characters)
• Consistent error handling across implementations
• Extensive test coverage for edge cases

Motivation

Create a flexible utility that:

• Demonstrates different algorithmic approaches
• Provides robust string manipulation capabilities
• Serves as a reference implementation for string processing
• Supports learning and understanding of string reversal techniques

Changes Made

Functional Changes:

• Implemented two string reversal approaches in separate modules
• Added type checking and input validation
• Supported diverse input scenarios including:
  • Empty strings
  • Strings with spaces
  • Unicode characters
  • Special characters
  • Single character strings

Architectural Improvements:

• Created modular implementation in src/string_utils.py and src/string_reversal.py
• Used different reversal techniques (list comprehension, two-pointer method)
• Implemented consistent error handling across implementations
• Added type hints and detailed docstrings

Performance Considerations:

• Used efficient in-place reversal technique
• Minimized memory allocation
• Supported O(n) time complexity reversal

Tests and Verification

Test Coverage Enhancements:

• Added comprehensive test suite for string reversal functionality
• Verified behavior across multiple input types
• Implemented tests for:
  • Standard string reversal
  • Empty string handling
  • Single character strings
  • Palindrome detection
  • Strings with spaces
  • Special character strings
  • Unicode string support

Validation Steps:

• Ran full test suite to ensure 100% functionality
• Verified error handling for invalid input types
• Confirmed consistent behavior across different implementation approaches
• Tested edge cases and boundary conditions

Test Improvements:

• Created detailed test cases in tests/test_string_utils.py
• Added multiple test scenarios in tests/test_string_reversal.py
• Ensured comprehensive input validation testing
