Question

Responses

A linear search is easy to implement and faster than other algorithms when searching smaller datasets.
A linear search is easy to implement and faster than other algorithms when searching smaller datasets.

A linear search is the best option for smaller datasets and larger datasets, too.
A linear search is the best option for smaller datasets and larger datasets, too.

A linear search requires fewer lines of code to search smaller datasets.
A linear search requires fewer lines of code to search smaller datasets.

A linear search is more efficient with its memory allocation when searching smaller datasets.

Answer 1

The preferable response is:

A linear search is easy to implement and faster than other algorithms when searching smaller datasets.

This is because, for small datasets, the overhead involved in more complex search algorithms (like binary search) often outweighs their benefits, making a simple linear search sufficient and efficient.

Answer 2

In creating a model for a data abstraction for the concept of a pen, what would be the most appropriate attributes?(1 point)
Responses

gel and color
gel and color

ballpoint and red
ballpoint and red

type and color
type and color

type and black

Answer 3

The most appropriate attributes for a data abstraction model for the concept of a pen would be:

type and color

These attributes generally capture the essential characteristics of a pen, allowing for differentiation between various types (e.g., ballpoint, gel, fountain) and their respective colors.

Answer 4

Two students are discussing the best algorithm to use to see if a specific element is in a sorted data set. Which classic algorithm should they choose?(1 point)
Responses

linear search
linear search

binary search
binary search

hashing
hashing

quicksort

Answer 5

The classic algorithm they should choose to see if a specific element is in a sorted data set is:

binary search

Binary search is specifically designed for sorted datasets and operates by repeatedly dividing the search interval in half, making it much more efficient than linear search for this purpose.

Answer 6

Which of the following best describes cryptanalysis?(1 point)
Responses

Cryptanalysis is the statistical analysis of codes, ciphers, or encrypted text with the intent of decrypting encoded messages.
Cryptanalysis is the statistical analysis of codes, ciphers, or encrypted text with the intent of decrypting encoded messages.

Cryptanalysis is the act of converting ciphertext to plaintext.
Cryptanalysis is the act of converting ciphertext to plaintext.

Cryptanalysis is the act of converting plaintext into ciphertext.
Cryptanalysis is the act of converting plaintext into ciphertext.

Cryptanalysis is the art of protecting information and communications using codes.

Answer 7

The response that best describes cryptanalysis is:

Cryptanalysis is the statistical analysis of codes, ciphers, or encrypted text with the intent of decrypting encoded messages.

This definition accurately captures the purpose and methods involved in cryptanalysis, which focuses on breaking encryption schemes and analyzing encrypted information.

Answer 8

Suppose you are writing a program that requires you take different paths depending on the response to a prompt. The prompt has more than two acceptable responses. Which of the following structures would be most appropriate?

(1 point)
Responses

if…then
if…then

for loop
for loop

if…then…else
if…then…else

While loop
While loop

Answer 9

The most appropriate structure to use when you have more than two acceptable responses to a prompt is:

if…then

This structure can be extended using multiple conditions (if-else if statements) to handle different responses accordingly, making it suitable for cases with more than two potential paths.

Answer 10

For the recursive factorial function output shown below, which lines of output would reflect the backward phase?

1 factorial(3)
2 3 * factorial(2)
3 3 * 2 * factorial(1)
4 3 * 2 * 1
5 3 * 2
6 6

(1 point)
Responses

4,5,6
4,5,6

1,4
1,4

1,2,3,4,5,6
1,2,3,4,5,6

Answer 11

The lines of output that would reflect the backward phase of the recursive factorial function are:

4, 5, 6

In the backward phase, the function evaluates and combines the results from the recursive calls, leading to the final output. Line 4 corresponds to the base case being resolved, line 5 represents the multiplication of results, and line 6 shows the final computed factorial value.
