Enhance Core Utility Functions: Advanced List Processing and String Manipulation

Description

Summary of Work

This pull request introduces robust utility functions for list processing and string manipulation, focusing on flexibility, performance, and comprehensive error handling.

Purpose

Develop a set of flexible, performant utility functions that provide:

• Advanced list flattening capabilities
• Efficient string reversal algorithm
• Comprehensive input validation
• Support for complex data structures

Key Benefits

• Improved code reusability across the project
• Enhanced error handling and input validation
• Support for nested and mixed-type data structures
• Efficient algorithmic implementations

Changes Made

Functional Enhancements:

• Implemented recursive list flattening function

  • Supports arbitrarily nested lists
  • Handles mixed-type list elements
  • Robust error handling for non-list inputs

• Developed in-place string reversal function

  • Efficient O(n) time complexity algorithm
  • Unicode and special character support
  • Comprehensive input type validation

Architectural Improvements:

• Modular design with clear separation of concerns
• Type hinting for improved code readability
• Comprehensive docstrings explaining function behavior
• Minimal external dependencies

Tests and Verification

Test Coverage Verification:

• 13 comprehensive test cases implemented

• Full coverage for list flattening functionality

  • Tested with simple, nested, and complex list structures
  • Validated handling of empty and mixed-type lists

• Extensive string reversal test suite

  • Verified basic, empty, and edge-case string reversals
  • Tested Unicode and special character support
  • Validated input type checking

Continuous Integration:

• All tests passing across multiple scenarios
• Consistent performance across different input types
• No regressions introduced
