Enhance Core Utility Functions: Array and String Processing Improvements

Description

Summary of Work

This pull request consolidates key improvements to our core utility functions, focusing on robust and flexible array and string manipulation capabilities.

Motivation

Our utility libraries now provide more comprehensive and reliable tools for common data transformation tasks, with a focus on:

• Flexible list flattening capabilities
• Efficient string manipulation
• Robust error handling
• Enhanced type safety

Key Benefits

• Improved data processing flexibility
• Consistent and predictable utility function behavior
• Support for complex nested data structures
• Comprehensive test coverage across various input scenarios

Future Outlook

These foundational improvements will support more complex data processing requirements, enabling more sophisticated transformations in our upcoming development phases.

Changes Made

Array Utilities

• Implemented recursive flatten_array() function
• Added support for deeply nested list structures
• Handled various input types and edge cases

String Utilities

• Developed in-place string reversal method
• Implemented robust input validation
• Supported complex string manipulation scenarios

Architectural Improvements

• Introduced type hinting
• Created modular, reusable utility functions
• Established consistent error handling patterns

Tests and Verification

Test Coverage

• Comprehensive test suite for array flattening

  • Nested list scenarios
  • Empty list handling
  • Mixed content lists

• String reversal test coverage

  • Unicode support
  • Palindrome handling
  • Input type validation

Verification

• 100% test pass rate across 13 test cases
• Tested edge cases and potential failure modes
• Ensured consistent behavior across different input types
