Data Structures Trees Interview Question:

What is threaded binary trees?

Submitted by: Administrator

In a threaded binary tree, if a node 'A' has a right child 'B' then B's left pointer must be either a child, or a thread back to A.

In the case of a left child, that left child must also have a left child or a thread back to A, and so we can follow B's left children until we find a thread, pointing back to A.

This data structure is useful when stack memory is less and using this tree the treversal around the tree becomes faster.
