Question

please answer c

a) The binary tree can be traversed by different ways. Describe the major difference
between preorder traversal algorithm and postorder traversal algorithm.
The difference between preorder traversal and postorder traversal is that in preorder
traversal, the order is roof, left, then right, while postorder is left, right, then root.
b) Given the following binary tree, what is the output (the sequence of nodes that are
visited) of preorder traversal algorithm?
Pre-order traversal: (root, left, right)
Output: A, B, D, E, G, C, F, H
c) Suppose a Binary TreeNode reference R refers to the root node of a binary tree, describe
the key algorithm to compute the total number of leaf nodes in the tree. Here, Rllink
is a reference that points to R's left child and Rrlink points is a reference that points to
A's right child.
