Answer:

total time to read whole file = ( 81.380208 mili seconds ) + 80ms + 80ms

Explanation:

Size of a surface = 675/15 = 45 MB

Size of a track = (Number of sectors per track)*(Size of a sector)

= (144*512)Bytes

= 73.728 KB

Number of tracks where 360KB file is located = 360/73.728 = 4.8828125 (Approx 5 tracks)

So Seek time to go the first track of the file = 80 ms

And after seek time for track to track movement = 4*20 = 80 ms

We need 4.8828125 rotations to read whole file.

Time for 4.8828125 ratations = (60.0/3600.0)*4.8828125 seconds = 0.081380208 seconds = 81.380208 mili seconds

So total time to read whole file = ( 81.380208 mili seconds ) + 80ms + 80ms

Answer:

file = open("numbers.txt")

numbers = []

for line in file:

   numbers.append(int(line))

print("The numbers in the file: " + str(numbers[0]) + " " + str(numbers[1]))

print("The sum of the numbers: " + str(numbers[0] + numbers[1]))

Explanation:

The code is in Python.

Open the file named numbers.txt

Create an empty list, numbers, to hold the numbers in the file

Create a for loop that iterates through file and adds the number inside the file to the list

Print numbers

Calculate and print the sum of the numbers

Final answer:

To read two integers from a file and print their sum, use a Python script to open the file, convert the strings to integers, calculate the sum, and print the results with the equation format.

Explanation:

To construct a program that reads the content from the file numbers.txt and prints out the two numbers along with their sum, you would need to use a programming language. Below is an example of how you might write such a program in Python:

with open('numbers.txt', 'r') as file:
   numbers = file.read().splitlines()

num1 = int(numbers[0])
num2 = int(numbers[1])
sum_of_numbers = num1 + num2

print(f"{num1} + {num2} = {sum_of_numbers}")

This program opens the file numbers.txt, reads its content line by line, converts the lines to integers, and then calculates their sum. Finally, it prints out the numbers and the sum in the format specified. It is assumed that numbers.txt contains one number per line and that these can be converted directly to integers.

1. The reason that Am..on (creator of Dynamo), G..gle (creator of Bigtable), and F...book (creator of Cassandra) allowed their employees to publish academic papers about the new breed of database technologies is that technologies were custom-made.

A custom-made technology is created specifically to meet some peculiar business strategies and cannot be utilized elsewhere.

2. The reason the companies did not keep these technologies as proprietary secrets is that other companies cannot use the technologies in their businesses since they were created to meet specific business requirements.

Database technologies are technologies that collect, store, organize, and process information and unstructured data for defined users. Some database technologies come in many shapes and sizes. Examples of database technologies include Dynamo, Bigtable, and Cassandra.

Final answer:

Companies like those who created Dynamo, Bigtable, and Cassandra published academic papers about their innovations to establish themselves as leaders, attract top talent, and foster adoption of their technologies as industry standards, despite the potential risk of giving away proprietary information.

Explanation:

The question asks why companies like those who created Dynamo, Bigtable, and Cassandra chose to publish academic papers about their database technologies, rather than keeping them as proprietary secrets. The decision to openly disclose information about these new database technologies can be attributed to several strategic advantages. First, publishing helps in establishing these companies as leaders in technological innovation, attracting top talent who want to work on cutting-edge projects. Furthermore, by sharing the innovations, these companies foster a community of developers who can contribute to the improvement of the technology, indirectly benefiting the original creators. Lastly, it encourages the adoption of their technologies as standards in the industry, which can lead to wider use and integration into other services, products, and technologies.

These reasons collectively contribute to why companies might decide to publish their innovations in the realm of big data and database technologies. Even though it might seem counterintuitive at first to share proprietary technologies, the long-term benefits of establishing industry standards, fostering a collaborative ecosystem, and attracting top talent can outweigh the risks of competitors gaining insights into their technologies.

Mutation Testing:

Mutation Testing is a type of software testing where we mutate (change) certain statements in the source code and check if the test cases are able to find the errors. It is a type of White Box Testing which is mainly used for Unit Testing. The changes in the mutant program are kept extremely small, so it does not affect the overall objective of the program.

We say a mutant is valid if it is syntactically correct. We say a mutant is useful if, in addition to being valid, its behavior differs from the behavior of the original program for no more than a small subset of program test cases.

VALID MUTANTS

1. if (x < 12 && (r – 3 > 12)) LOR

2. if (x < 12 || (r – 3 < 12)) ROR

3. if (x < 12 || (x – 3 < 12)) IVR

INVALID MUTANTS

1. if (x < 12 ||(r – 3 > 12) UPR

2. if (x < 12 (r – 3 < 12)) MLO

3. (x < 12 || (x – 3 < 12)) CSM

Note:

LOR: LOGICAL OPERATOR REPLACEMENT

ROR: RELATIONAL OPERATOR REPLACEMENT

IVR: INVALID VARIABLE REPLACEMENT

UPR: UNBALENCED PARANTHISIS REPLACEMENT

MLO: MISSING LOGICAL OPERATOR REPLACEMENT

CSM: CONTROL OPERATOR MISSING REPLACEMEN

Answer:

Changing the customer number on a record in the Orders table to a number that does not match a customer number in the customer table would violate referential integrity.

If deletes do not cascade, deleting a customer that has orders would violate referential integrity.

If deletes cascade, customer can be deleted and all orders for that customer will automatically be deleted.

Final answer:

To determine the number of coins that player 2 will spend in a given round of the game, check the rules based on the value of the round: divisible by 3 = 3 coins, divisible by 2 but not by 3 = 2 coins, not divisible by 3 and not divisible by 2 = 1 coin.

Explanation:

To determine the number of coins that player 2 will spend in a given round of the game, we need to check the rules based on the value of the round:

If the round is divisible by 3, player 2 will spend 3 coins.

If the round is not divisible by 3 but is divisible by 2, player 2 will spend 2 coins.

If the round is not divisible by 3 and not divisible by 2, player 2 will spend 1 coin.

So, the method getPlayer2Move should be defined as follows:

public

int getPlayer2Move(int round)

{

if (

round % 3 == 0) { return 3;

}

else if

(

round % 2 == 0

) {

return 2;

} else {

return 1;

} }

Final answer:

The getPlayer2Move method returns 1, 2, or 3 based on the given rules.

Explanation:

The method getPlayer2Move returns 1, 2, or 3 based on the rules given in the question. If the round number is divisible by 3, the method returns 3. If the round number is not divisible by 3 but is divisible by 2, the method returns 2. If the round number is not divisible by 3 and not divisible by 2, the method returns 1. For example, if the round number is 4, which is divisible by 2 but not divisible by 3, the method would return 2.

Answer:

Prior Experience Working with Senior Officers versus Little or None.

Explanation:

Differences and disparities between the Services in career paths leading up to a joint assignment may surprise new staff officers in joint assignments.

For example, Army and Air Force officers will likely come to a joint assignment with prior junior officer experience as an administrative “exec” to a senior officer at the O-5 and above level.

In contrast, Navy, Marine Corps and Coast Guard officers will have had no such experience unless selected for one of the highly competitive Flag Aide or Aide-de-Camp billets to an O-7 or above who rates such an aide.

Having an experience working with senior officers and when a person has little or none shows the key element to remember when working with other services.

The act of working together in a joint project helps to provide some amount of guidance for the use of authority.

Note that having a previous experience in working with senior officers and when a person has little or none can be obviously shown when working with other services.

Answer:

=($B$4 * B23)

Explanation:

Given

Billable Rate: B4

Total Billable Hours: B23

Required:

Daily Bill: B25

Write the following formula in cell B25

=($B$4 * B23)

The question asks that the cell for billable rate should be referenced using the absolute cell reference.

To use absolute reference in a cell, we start by writing a dollar sign and we also separate the cell name and the cell number with a dollar sign.

Hence, cell B4 becomes $B$4

Also, the question asks that the cell $B$4 be multiplied by cell B23.

To write a formula in Excel, we start by writing the equal to sign (=), then we continue with the expression itself

$B$4 multiplied by cell B23 will be written as $B$4 * B23

So, the full formula to calculate daily bill that'll be written in cell B25 becomes is =($B$4 * B23)

The Excel formula in cell B25 that can be used to calculate the daily bill for Monday, July 29 is =($B$4 × B23)

An excel formula represents the expression of a code in an Excel sheet that operates within a range of cell(s).

From the parameters  given:

By using the absolute reference for billable rate, we need to begin the formula with a $ sign, the cell name in conjunction with the cell number is being separated by a $ sign.

Therefore, the cell in B4 can be written as:

Now, multiplying it with cell in B23, we have using the excel formula method, we have:

=($B$4 × B23)

Answer:

import java.util.*;

public class num3 {

   public static void main(String[] args) {

   String sentence = "All good people";

       System.out.println("The vowels in the sentence are ");

       returnVowels(sentence);

   }

   public static void returnVowels(String word){

       String newWord = word.toLowerCase();

       String vowels ="";

       for (int i = 0; i < newWord.length(); i++){

           if(newWord.charAt(i)=='a'||newWord.charAt(i)=='e'||newWord.charAt(i)==i||

           newWord.charAt(i)=='o'||newWord.charAt(i)=='u'){

               vowels = vowels+newWord.charAt(i);

               //System.out.print(newWord.charAt(i)+" ");

           }

       }

       String [] chars = vowels.split("");

       Set<String> uniqueVowels = new LinkedHashSet<>();

       for (String s : chars) {

           uniqueVowels.add(s);

       }

       System.out.println(uniqueVowels);

   }

}

Explanation:

In Java

Create the method/function to receive a string as argument

Change the string to all small letters using the toLowerMethod

Iterate through the string using if statement identify the vowels and store in a new String

Since the sentence does not contain unique vowel characters, use the set collections in java to extract the unique vowels and print out

Iterators in C++

==================

Iterators are used to point at the memory addresses of STL containers. They are primarily used in sequence of numbers, characters etc. They reduce the complexity and execution time of program.

Operations of iterators :-

1. begin() :- This function is used to return the beginning position of the container.

2. end() :- This function is used to return the after end position of the container.

// C++ code to demonstrate the working of

// iterator, begin() and end()

#include<iostream>

#include<iterator> // for iterators

#include<vector> // for vectors

using namespace std;

int main()

{

vector<int> ar = { 1, 2, 3, 4, 5 };

// Declaring iterator to a vector

vector<int>:: iterator ptr;

// Displaying vector elements using begin() and end()

cout << "The vector elements are : ";

for (ptr = ar. begin(); ptr < ar. end(); ptr++)

cout << *ptr << " ";

return 0;

}

Iterators in Java

==================

‘Iterator’ is an interface which belongs to collection framework. It allows us to traverse the collection, access the data element and remove the data elements of the collection.

java. util package has public interface Iterator and contains three methods:

boolean hasNext(): It returns true if Iterator has more element to iterate.

Object next(): It returns the next element in the collection until the hasNext()method return true. This method throws ‘NoSuchElementException’ if there is no next element.

void remove(): It removes the current element in the collection. This method throws ‘IllegalStateException’ if this function is called before next( ) is invoked.

// Java code to illustrate the use of iterator

import java. io.*;

import java. util.*;

class Test {

public static void main(String[] args)

{

ArrayList<String> list = new ArrayList<String>();

list. add("A");

list. add("B");

list. add("C");

list. add("D");

list. add("E");

// Iterator to traverse the list

Iterator iterator = list. iterator();

System. out. println("List elements : ");

while (iterator. hasNext())

System. out. print(iterator. next() + " ");

System. out. println();

}

}

Every class that implements Iterable interface appropriately, can be used in the enhanced For loop (for-each loop). The need to implement the Iterator interface arises while designing custom data structures.

Example:

for(Item item: customDataStructure) {

   // do stuff

}

To implement an iterable data structure, we need to:

Implement Iterable interface along with its methods in the said Data Structure

Create an Iterator class which implements Iterator interface and corresponding methods.

We can generalize the pseudo code as follows:

class CustomDataStructure implements Iterable<> {

// code for data structure

public Iterator<> iterator() {

return new CustomIterator<>(this);

}

}

class CustomIterator<> implements Iterator<> {

// constructor

CustomIterator<>(CustomDataStructure obj) {

// initialize cursor

}

// Checks if the next element exists

public boolean hasNext() {

}

// moves the cursor/iterator to next element

public T next() {

}

// Used to remove an element. Implement only if needed

public void remove () {

// Default throws Unsupported Operation Exception.

}

}

Note: The Iterator class can also, be implemented as an inner class of the Data Structure class since it won’t be used elsewhere.

Answer:

I have answered the first part in another question of yours, but the second part is in the provided screenshot!

Explanation:

Steps to solve this problem:

Go through all the numbers from 1 -> n1, every time you go through each of these numbers, go through all the numbers from 1 -> n2. Multiply these numbers and add them to an output string. Print each line of output.

Answer:

#include <stdio.h>

int main()

{

   float afTest1[5] = {90, 30, 25, 45, 55};

   for (int i = 0; i < 5; i++) {

       printf("%f ", afTest1[i]);

   }

   return 0;

}

Explanation:

Initialize the elements of the array as 90, 30, 25, 45, 55

Create a for loop that iterates through the array

Inside the loop, print each element using printf function

Answer:

enum Flower { ROSE, DAISY, PETUNIA }

Flower flora = Flower.ROSE

Explanation:

Flower is of Enumeration data type and it contains the constants ROSE, DAISY and PENTUA.

To write a statement that declares a variable of that type you use

Var_of_enum_type Var_name

And to initialize it with a constant of the enumeration data type you use the dot (.) operator.

Var_of_enum_type.CONSTANT
