Question
Chapter 7, Problem 55E
Program Plan Intro
a.
Top-down design process:
- In the top-down design process, the problem is placed on the top of the layer.
- In each succeeding level, it is divided into small problems and is further divided into smaller problems in its sub layer.
- In this method, the problem is systematically broken into small problems, which is more convenient.
- It is complicated to resolve big problems as compared to smaller problems.
Explanation of Solution
b.

Sign on to the Internet
Load the search engine.
Enter in "Find phone number"
Load the initial response
Get the phone number
Sign out from the site
E...
Explanation of Solution
c.
Top-down design for finding a telephone number on a scrap of paper that have lost:
Look out the wallets for scrap of paper.
//Performs "WHILE" loop to finding wallets
WHILE (paper is not existing and more wallets are there)
//Determine next one
Find next one
//If the paper is existing, then
IF (paper is present)
//Display the given paper
Paper is found
Look out the waste paper baskets for scrap of paper.
//Performs "WHILE" loop to finding paper baskets
WHILE (paper is not existing and more waste paper baskets are there)
//Determine next one
Find next one
//If the paper is existing, then
IF (paper is present)
//Display the given paper
paper is found

The Horse table has the following columns:
ID - integer, auto increment, primary key
RegisteredName - variable-length string
Breed - variable-length string
Height - decimal number
BirthDate - date
Delete the following rows:
Horse with ID 5
All horses with breed Holsteiner or Paint
All horses born before March 13, 2013
To confirm that the deletes are correct, add the SELECT * FROM HORSE; statement.
Why is Linux popular? What would make someone choose a Linux OS over others? What makes a server? How is a server different from a workstation? What considerations do you have to keep in mind when choosing between physical, hybrid, or virtual server and what are the reasons to choose a virtual installation over the other options?
Objective you will:
1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five)
2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector.
3. Compare the performance of TreeSort with C++'s std::sort on large datasets.
Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST):
1. Insert all elements into a BST (logically sorting them).
2. Traverse the BST in-order to extract elements in sorted order.
3. Store the sorted elements in a vector.
Time Complexity
Operation Average Case Worst Case (Unbalanced Tree)Insertion 0(1log n) 0 (n)Traversal (Pre-order) 0(n) 0 (n)Overall Complexity 0(n log n) 0(n^2) (degenerated tree)
Note: To improve performance, you could use a…
