4. (15 points) Give an algorithm that takes as input a positive integer n and a number x, and computes xn (i.e., x raised to the power n) by performing O(lgn) multiplications. Your algorithm CANNOT use the exponentiation operation, and may use only the basic arithmetic operations (addition, subtraction, multiplication, division, modulo). Moreover, the total number of basic arithmetic operations used should be O(lgn).

Answers

Answer 1

Answer:

The algorithm is as follows:

Exponent(x, n):

if(n == 0):  

    return 1

pr = Exponent(x, int(n / 2))

if (n % 2 == 0):

 Return pr* pr

else:

 if(n > 0):  

     Return x * pr* pr

 else:  

     Return (pr* pr) / x

Explanation:

In order to get a O(log n) time complexity, a recursive procedure is implemented by the algorithm

The algorithm begins here

Exponent(x, n):

If n is 0, the procedure returns 1

if(n == 0):  

    return 1

This recursively calculates the product of x, n/2 times

pr= Exponent(x, int(n / 2))

If n is even, the square of prod (above) is calculated  

if (n % 2 == 0):

 Return pr* pr

If otherwise (i.e. odd)

else:

If n is above 0, the square of prod multiplied by x is calculated

 if(n > 0):  

     Return x * pr* pr

If otherwise, the square of prod divide by x is calculated

 else:  

     Return ([tex]pr* pr[/tex]) / x

The time complexity is: O(log|n|)

Social engineering is a tactic used by attackers to manipulate individuals into divulging sensitive information or performing actions that may be harmful to the organization.

Social engineering attacks exploit human psychology, emotions, and trust to trick people into revealing sensitive information or performing actions that they otherwise wouldn't. The attacks can take many forms, such as phishing emails, phone scams, pretexting, and baiting.

What is social engineering?

The prevalence of social engineering attacks has increased in recent years, as attackers have become more sophisticated and creative in their methods.

According to the Verizon Data Breach Investigations Report (DBIR) in 2020, social engineering is used in 84% of successful cyber attacks and the most common form of social engineering is phishing. It is also reported that around 30% of phishing messages are opened and 12% of recipients click on the malicious link.

When it comes to combating social engineering, both employees and management carry some level of responsibility. Employees are the first line of defense and play a vital role in protecting the organization's sensitive information. They should be educated and trained on how to identify and avoid social engineering attacks. Management, on the other hand, is

Directions :: Write a Ship class. Ship will have x, y, and speed properties. x, y, and speed are integer numbers. You must provide 3 constructors, an equals, and a toString for class Ship.



One constructor must be a default.

One constructor must be an x and y only constructor.

One constructor must be an x, y, and speed constructor.

Provide all accessor and mutator methods needed to complete the class.

Add a increaseSpeed method to make the Ship speed up according to a parameter passed in.

Provide an equals method to determine if 2 Ships are the same(i.e. in the same location).

You also must provide a toString() method.

The toString() should return the x, y, and speed of the Ship.



In order to test your newly created class, you must create another class called ShipRunner. There you will code in the main method and create at least 2 Ship objects (although you can create more if you like), using the constructors you created in the Ship class. Then you will print them out using the toString method and compare them with the equals method.

Write a procedure ConvertToBinary that takes an input as a number from 0 to 16 (including 0 but not 16) and converts it to a binary number. The binary number should be returned as a list.

Answers

Sure, here's an example of a Python function that converts a decimal number to binary and returns the result as a list:

def ConvertToBinary(decimal):

binary = []

while decimal > 0:

remainder = decimal % 2

binary.append(remainder)

decimal = decimal // 2

return binary[::-1]

The function takes in an input decimal which is a number between 0 and 16 (not including 16) and uses a while loop to repeatedly divide the decimal number by 2 and take the remainder. The remainders are then appended to a list binary. Since the remainders are appended to the list in reverse order, the result is reversed by slicing the list [-1::-1] to give the proper order.

You can also add a check to make sure that the input is within the required range:

def ConvertToBinary(decimal):

if decimal < 0 or decimal >= 16:

return None

binary = []

while decimal > 0:

remainder = decimal % 2

binary.append(remainder)

decimal = decimal // 2

return binary[::-1]

this way you can make sure that the input provided is within the allowed range.

Assume the first part of your code chunk is:

flavors_df %>%

What code chunk do you add to change the column name?

Answers

Answer:

You can use the rename function to change the column name. Here is an example code chunk:

flavors_df %>%

rename(Company = Company...Maker.if.known.)

This will rename the Company...Maker.if.known. column to Company. Note that the old column name is surrounded by backticks () because it contains a period, which is a special character in R. The new column name, Company`, does not need to be surrounded by backticks because it does not contain any special characters.

List 2 or 3 visual aids that you might use during a speech on "Technology in the Classroom" (or a topic of your choosing) to illustrate your main points, and explain exactly how you plan to use them. (Site 1)

Answers

Answer:

Graphs or charts: I would use graphs or charts to illustrate the trend of technology usage in the classroom over time. For example, I could show a line graph that compares the percentage of classrooms that had no technology, limited technology, or full technology access in the past decade. This would allow the audience to see the increasing trend of technology adoption in the classroom and better understand the impact that technology is having on education.

Photos or videos: I would use photos or videos to provide concrete examples of how technology is being used in the classroom to enhance teaching and learning. For example, I could show a video of a teacher using a virtual reality headset to take her students on a virtual field trip to a museum, or I could show a series of photos of students using tablets or laptops to complete assignments and collaborate with their peers. These visual aids would help the audience to better understand the specific ways in which technology is being used in the classroom and how it is benefiting students and teachers.

Infographic: I would use an infographic to present a summary of the main points of my speech in a visually appealing and easy-to-understand format. The infographic could include bullet points or graphics that highlight the key benefits of technology in the classroom, such as increased engagement, improved learning outcomes, and enhanced collaboration. By presenting the information in this way, I could help the audience to quickly grasp the main points of my speech and better retain the information.

Answers

Since the business wants to evaluate how much they're spending on their customers, versus how much their customers go on to spend. The measurement that a business would use to evaluate how much a customer will spend during the time they are a customer is called Customer Lifetime Value (CLV).

What is Customer Lifetime Value (CLV)?

CLV is a prediction of the net profit attributed to the entire future relationship with a customer. It is calculated by multiplying the average value of a sale by the number of repeat transactions and the average retention time.

Therefore, based on the above, CLV can be used to identify which customers are the most valuable to a business and to allocate resources accordingly.
