Implement Recursive Array Flattening Function with Comprehensive Test Coverage

Description

Task

Create Array Flattening Function

Acceptance Criteria

• Function should handle arrays of any nesting depth
• Should preserve order of elements
• Should handle empty arrays and non-array elements
• Should work with mixed data types

Summary of Work

Overview

This pull request implements a robust and flexible array flattening function that can handle nested arrays of varying depths and types.

Implementation Details

• Location: src/array_utils.py
• Function: flatten_array()
• Approach: Recursive implementation with comprehensive type handling

Key Features

• Handles arbitrary levels of nested lists
• Supports mixed data types
• Works with empty lists, single elements, and complex nested structures
• Type-annotated for improved code clarity

Implementation Highlights

• Recursive algorithm that extends flattened results
• Handles base cases:
  • Non-list inputs (converted to single-element list)
  • Empty lists
  • Nested lists with multiple levels

Testing Approach

• Created comprehensive test suite in tests/test_array_utils.py
• Test coverage includes:
  1. Simple list flattening
  2. Nested list flattening
  3. Deeply nested list flattening
  4. Empty list handling
  5. Single element handling
  6. Mixed type handling
  7. Complex nesting scenarios

Test Results

• All 7 test cases passed successfully
• 100% coverage of expected functionality
• Verified robust handling of various input types and structures

Acceptance Criteria Met

• Create a function to flatten nested arrays
• Handle multiple levels of nesting
• Support different data types
• Comprehensive error handling
• Thorough test coverage

Notes

• Function is pure and does not modify the original input
• Implemented with type hints for better type safety
• Follows Pythonic principles of simplicity and readability

Changes Made

• Created src/array_utils.py with recursive flatten_array() implementation
• Implemented type-annotated function with comprehensive input handling
• Added docstring with function description and examples
• Created tests/test_array_utils.py with comprehensive test cases
• Ensured 100% test coverage for various input scenarios

Tests

• Test simple list flattening
• Test nested list flattening
• Test deeply nested list flattening
• Test empty list handling
• Test single element handling
• Test mixed type handling
• Test complex nesting scenarios
