Implement Robust String Reversal Functionality with Comprehensive Test Coverage

Description

Summary of Work

This pull request introduces a robust and efficient string reversal utility with extensive input handling and validation. The implementation provides a flexible solution for reversing strings across various use cases, ensuring reliability and performance.

Key Objectives:

• Develop a performant in-place string reversal mechanism
• Implement comprehensive input validation
• Provide robust handling of edge cases
• Ensure high-quality test coverage across different scenarios

The utility is designed to be both flexible and secure, handling diverse input types while maintaining predictable behavior.

Changes Made

Functional Modifications:

• Implemented two-pointer string reversal algorithm
• Added robust type checking for input validation
• Supported reversal of strings with:
  • Alphanumeric characters
  • Special characters
  • Spaces
  • Mixed character types

Architectural Improvements:

• Created modular, single-responsibility function
• Implemented efficient O(n) time complexity reversal
• Designed with clear error handling and type safety
• Minimal memory overhead using in-place reversal technique

Tests and Verification

Test Coverage Verification:

• Implemented 7 comprehensive test cases covering:
  • Basic string reversal
  • Empty string handling
  • Single character reversal
  • Strings with spaces
  • Strings with special characters
  • Mixed character scenarios
  • Invalid input type detection

Validation Approach:

• Used pytest for comprehensive test suite
• Verified all test cases pass successfully
• Tested edge cases and potential error scenarios
• Ensured TypeError raises for invalid inputs
