Enhance Core Utility Functions: Data Transformation, Search, and Parsing Improvements

Description

Summary of Work

This pull request consolidates multiple improvements to core utility functions across different modules, focusing on enhancing functionality, error handling, and code robustness.

Key Objectives:

• Standardize utility function implementations
• Improve input validation and error handling
• Provide flexible and reliable data transformation utilities
• Ensure comprehensive test coverage for edge cases

The changes span multiple utility functions including array flattening, binary search, RGB to hex conversion, string manipulation, and URL parsing. Each module has been carefully refined to provide more reliable and predictable behavior across various input scenarios.

Changes Made

Functional Improvements:

• Array Flattener: Enhanced nested list handling with comprehensive input validation
• Binary Search: Improved search algorithm robustness, handling edge cases like empty lists and duplicate elements
• RGB to Hex Conversion: Added extensive input type and value range checking
• String Reversal: Implemented flexible string manipulation with special character support
• URL Parser: Strengthened URL parsing logic to handle complex and minimal URL structures

Architectural Enhancements:

• Consistent error handling approach across utility functions
• Modular design allowing easy extension and maintenance
• Improved input validation patterns
• Minimal side-effect implementations

Tests and Verification

Test Verification Steps:

• Executed full test suite covering 35 test cases across 5 utility modules
• Validated all tests passing without any failures
• Comprehensive coverage including:
  • Positive test scenarios
  • Negative input handling
  • Edge case detection
  • Type safety checks

Test Coverage Highlights:

• 100% passing rate for all existing test cases
• Tested various input types and scenarios
• Verified error handling mechanisms
• Ensured no regressions in existing functionality
