Enhance Data Manipulation Utilities: Array Flattening and String Processing

Description

Summary of Work

This pull request consolidates improvements to core data manipulation utilities, focusing on robust array flattening and string reversal functions. The changes aim to provide more flexible and resilient utility functions for handling complex data transformations.

Key Objectives:

• Implement a comprehensive array flattening utility that handles various nested list scenarios
• Create a flexible string reversal function with extensive input handling
• Ensure high-quality, production-ready utility functions with comprehensive test coverage

Benefits:

• Improved input validation and error handling
• Support for complex nested data structures
• Clean, maintainable implementation of common data manipulation tasks

Changes Made

Functional Enhancements:

• Array Flattener:

  • Implemented recursive flattening for nested lists
  • Added support for handling lists with multiple nesting levels
  • Robust error handling for invalid input types

• String Reversal:

  • Developed a versatile string reversal function
  • Implemented handling for edge cases (empty strings, special characters)
  • Ensured compatibility with different string input types

Architectural Improvements:

• Modular design allowing easy integration into larger projects
• Minimal dependencies
• Clear, readable implementation following Python best practices

Tests and Verification

Test Coverage:

• Comprehensive test suite for array flattener (7 test cases)

  • Verified handling of simple and deeply nested lists
  • Tested empty list scenarios
  • Validated input type checking

• Extensive string reversal tests (7 test cases)

  • Covered basic reversal scenarios
  • Tested edge cases including empty strings and special characters
  • Validated error handling for invalid inputs

Verification Steps:

• Full test suite execution with 100% pass rate
• Validated functionality across different input types
• Ensured no regressions in existing functionality
