Expert Solution & Answer
Chapter 20, Problem 14RQE
Explanation of Solution
Pseudocode
Pre-order Traversal:
In the pre-order traversal, initially it visits the root node, then traverses the left sub tree, and finally it traverses the right sub tree.
Pseudocode:
In this algorithm, recursion of binary tree “T” is “T’”, let us consider “N” denote the root of a subtree of “T’”, “L” is the subtree of “T’”, whose root is the left child of “N”, and “R” be the subtree of “T’”, whose root is the right child of “N”.
Input: T, a binary tree
Output: The contents of the nodes of T displayed in PreOrder
Algorithm:
if T is not empty then
