Enhance String Manipulation Utilities with Robust Reversal Implementations

Description

Summary of Work

This pull request consolidates and standardizes string manipulation utilities across the project, focusing on creating robust and flexible string reversal functionality.

Key Objectives:

• Provide multiple, complementary string reversal implementations
• Ensure consistent error handling and input validation
• Improve code reusability and maintainability
• Demonstrate different algorithmic approaches to string manipulation

Project Impact:

• Introduces flexible string utility functions
• Supports complex string processing scenarios
• Provides a foundation for advanced text manipulation techniques

Strategic Considerations:

• Supports unicode and special character handling
• Implements explicit type checking
• Uses manual reversal techniques without relying on built-in methods
• Demonstrates algorithmic problem-solving approaches

Changes Made

Functional Enhancements:

• Implemented two distinct string reversal approaches
• Added comprehensive input validation
• Supported diverse string manipulation scenarios

Algorithmic Implementations:

• Two-pointer technique in string_reversal.py
• Iterative reverse approach in string_utils.py

Error Handling Improvements:

• Consistent TypeError handling for invalid inputs
• Explicit type checking before string manipulation
• Robust handling of edge cases (empty strings, special characters)

Tests and Verification

Test Coverage Highlights:

• 14 comprehensive test cases across two test suites
• Validated string reversal for multiple scenarios:
  • Standard string reversal
  • Empty string handling
  • Unicode character support
  • Special character processing
  • Invalid input type detection

Test Verification:

• 100% test pass rate
• Covered multiple implementation strategies
• Ensured consistent behavior across different reversal methods
