Question

Suppose we have an ArrayHeap<int> that uses the array representation from class (also called "tree representation 38" in lecture). Recall that in this representation that the leftmost item is unused.
Consider a heap with the following underlying array.
-8 5 -2 9 8 01 10 10 12
Suppose we perform a pre-order traversal of the heap represented by this array. What will be the last value in the pre-order traversal?

Add Boolean instance variables to indicate whether a node pointer is a thread or regular pointer. You may not add any additional pointers to BSTNode. The whole idea of threads is that they take advantage of unused BSTNode pointers and thereby reduce the binary tree’s wasted overhead. Add setter/getter methods to access the Boolean instance variables or modify existing setters/getters as necessary.
