The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is A: counter module.

Counter module in python or Python counter is a container that holds the count of each of the elements present in the container. It is a sub-class available in the dictionary class. Jamal can use this module in Python to write a program that will find the 10 most common words in Romeo and Juliet.

Other options are not correct because:

While loop: while loop only iterates its body until a specific condition is met. For loop is used to iterate to a pre-specified condition and iterate until the condition is reached. While the mean module of Python is used to calculate mean and average.

Convert 1.5GB to KBs = 1500000kb

1500000kb/950kb ≈ 1579

Explanation:

A flash disk is a storage device. It has enough memory to store large files. In the given question, the flash disk has a memory of 1.5GB and can store 1578.94 music files of 950KBs each.

A flash disk is a data storage device that uses flash memory specifically : a small rectangular device which is designed to be plugged directly into a USB port on a computer. It is often used for transferring files from one computer to another computer system.

Flash disks have no mechanical platters or access arms. It is termed "disk" because of the data which are accessed as if they were on a hard drive. The disk storage structure is emulated.

In the given question, the flash disk contains 1.5GB memory and has to store music files of 950KBs each. For determining the number of music files which can be stored in the flash disks, we have to first convert the unit of flash disk from GB to KB:

1GB = 1,000,000 KB

1.5 GB = 1,500,000 KB

size of music file = 950 KB

Number of music files that can be stored = storage in the flash disk ÷ size of the music file

Number of music files = 1500000KB ÷ 950KB

Number of music files = 1578.94

Explanation:

DDE (direct data entry) devices are the devices that read data from a source and transfer it directly into the computer. Unlike, other input devices which require physical interaction which requires you to move physically or to do something for an output or feeding data into a computer.  

The DDE devices require no hard work while taking input into the computer as compared to other input devices. These DDE devices made our life very easy. Because these devices take input accurately and there are no chances of human error.

The example of DDE devices are magnetic stripe reader, chip reader, Pin pads, optical mark reader, and barcode reader, etc.

These devices have brought great advantages to human life. Because by using these data entry devices, information can be put into very quickly, more accurate than typing and information of the whole page transferred .very quickly and accurately into the system. These devices are also more secure and can hold lots of data, and the data is protected with the PIN (personal identification number). These are also used in ATM machines, handheld, and entry doors.

answer : 0 (n log n )

Explanation:

Creating an AVL tree containing the same values and containing N integers and without destroying the original BST in the process, the worst case time will be : 0 ( n log n ) and this is because each insertion will take 0 (log n ) time

The worst case time for a binary search algorithm that contain N integers without destroying the original binary search tree (BST) is [tex]0(NlogN)[/tex]

Binary search can be defined as an efficient algorithm that is designed and developed for searching an element from a sorted list of data, especially by using the run-time complexity of [tex]0(logN)[/tex].

Note: N is the total number of elements contained in a list.

In this scenario, the worst case time for this binary search algorithm that contain N integers without destroying the original binary search tree (BST) is given by [tex]0(NlogN)[/tex]

Answer: rent

Answer:

rent

Explanation:

took the quiz

Answer:

Explanation:

The following is written in Java. It is a method/function that takes the oldScore as an int input. It turns it into a String, separates all the digits, puts them into an array. Then adds the first digit to the end and removes it from the beginning, thus shifting the entire score one to the left. Then it turns the String variable back into an Integer called finalScore and prints it out.

public static void newScore(int oldScore) {

       ArrayList<Integer> newScore = new ArrayList<>();

       String stringOldScore = String.valueOf(oldScore);

       for (int x = 0; x < stringOldScore.length(); x++) {

           newScore.add(Integer.parseInt(String.valueOf(stringOldScore.charAt(x))));

       }

       newScore.add(newScore.get(0));

       newScore.remove(0);

       String newScoreString = "";

       for (int x:newScore) {

           newScoreString += String.valueOf(x);

       }

       int finalScore = Integer.parseInt(newScoreString);

       System.out.println(finalScore);

   }

Answer:

Explanation:

The following code is written in Java. It asks the user for an input and saves it in a String variable. Then it loops through all the characters in the string and counts the spaces. Finally, it prints the total number of spaces in the String.

       Scanner in = new Scanner(System.in);

       System.out.println("Enter Line Now:");

       String userInput = in.nextLine();

       int spaceCount = 0;

       for (int x = 0; x < userInput.length(); x++) {

           if (userInput.charAt(x) == ' ') {

                max = numbers[i][j];

        }

    }

    System.out.println("The max is " + max);

}

}

Explanation:

*The code is in Java.

Create a function called findmax() that takes one parameter, numbers array

Inside the function:

Initialize the max as first number in the array

Create a nested for loop that iterates through the array. Inside the second for loop, check if a number is greater than the max. If it is set it as the new max

When the loop is done, print the max

Inside the main:

Initialize a 2D array called numbers

Create a nested for loop that sets the random numbers to the numbers array. Note that to generate random integers, nextInt() function in the Random class is used

Create another nested for loop that displays the content of the numbers array

Call the findmax() function passing the numbers array as a parameter

Explanation:

Analyzing the given code segment

In class Dance,

A method named dance was defined with an instance of two string variables/values

which are name and song

public Dance(String name, String s)

In the main of the program,

The first line creates an instance of Dance as dance1

dance1 is initialized with the following string values: "Tango","Hernandos Hideaway"

- The first string value "Tango" will be passed into the name variable of the Dance method

- The second string value "Hernandos Hideaway" will be passed into the song variable of the Dance method

Next, another instance of Dance is initialized as dance2

dance2 is initialized with the following string values: "Swing","Hound Dog"

- The first string value "Swing" will be passed into the name variable of the Dance method

- The second string value "Hound Dog" will be passed into the song variable of the Dance method

On line 3 of the main: System.out.println(dance1.toString());

The values of dance1, which are "Tango","Hernandos Hideaway" are printed

On line 4 of the main: System.out.println(dance2.toString());

The values of dance1, which are "Swing","Hound Dog" are printed

Hence, option d answers the question
