Question
The null left pointer pointing to predecessor and null right pointer pointing to successor. how many types of threaded tree are possible with this convention?
Solution
There are two types of threaded trees possible with this convention:
-
Single Threaded: Each node is threaded towards either its in-order predecessor or successor (i.e., left or right) meaning that each node has a single thread.
-
Double Threaded: Each node is threaded towards both the in-order predecessor and successor (i.e., both left and right) meaning that each node has two threads.
