Add Binary Tree Traversal Algorithm

[staging-devin-ai-integration]

Binary Tree Traversal Algorithm Implementation

Purpose

This pull request implements a binary tree traversal algorithm in Python, adding new functionality to the marcosfede/algorithms repository. The implementation includes inorder, preorder, and postorder traversal methods for binary trees.

Implementation Details

• Created a new file binary_tree_traversal.py in the tree directory.
• Implemented TreeNode class for representing nodes in a binary tree.
• Implemented BinaryTreeTraversal class with the following methods:
  • inorder_traversal
  • preorder_traversal
  • postorder_traversal
• Each traversal method uses a recursive helper function for efficient traversal.
• Added example usage in the __main__ section of the file.

Testing

• Created a new file test_binary_tree_traversal.py in the tree directory.
• Implemented unit tests for:
  • Empty tree
  • Single node tree
  • Sample tree with multiple nodes
• All tests pass successfully, ensuring the correctness of the implementation.

Benefits

• Provides a clear and efficient implementation of common binary tree traversal algorithms.
• Enhances the repository's collection of tree-related algorithms.
• Includes comprehensive tests for reliability and maintainability.

Next Steps

• Consider adding iterative versions of the traversal algorithms for comparison.
• Explore the possibility of adding more advanced tree traversal techniques (e.g., level-order traversal).

Please review the changes and provide any feedback or suggestions for improvement.
