What are some advanced techniques for binary tree traversal?

Some advanced techniques include Morris traversal, level order traversal using two queues, and depth-first traversal with iterative methods.

Can you explain Morris traversal in detail?

Morris traversal is a way to traverse a binary tree without using extra space. It modifies the tree structure temporarily to create links between nodes.

What are the advantages of using Morris traversal?

The main advantage is that it uses O(1) space, making it efficient for large trees. It also has a time complexity of O(n).

Are there any drawbacks to Morris traversal?

Yes, since it modifies the tree structure, it can lead to issues if the tree is used concurrently or if the modifications are not restored.

What other traversal techniques should I know?

You might want to explore depth-first search, breadth-first search, and various tree balancing techniques for optimal traversal.
