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

Given an JavaScript object list of books that each have a pages attribute to define the number of pages in the book, find the product of all the pages in the object list of books using recursion (you must use recursion to solve this problem).
Keep in mind:
The input list object may be completely empty (ex. {})
The next attribute may not be defined
function getPageCount(list) {// your code here// returns an integer}Example test case:Input: {"book":"A","pages":1,"next":{"book":"B","pages":2,"next":{"book":"C","pages":3,"next": null}}}Output: 6Reasoning: 1 * 2 * 3 pages
