Write a program that reads in 10 numbers from the user and stores them in a 1D array of size 10. Then, write BubbleSort to sort that array – continuously pushing the largest elements to the right side

Answers

Answer:

The solution is provided in the explanation section.

Detailed explanation is provided using comments within the code

Explanation:

import java.util.*;

public class Main {

//The Bubble sort method

public static void bb_Sort(int[] arr) {

int n = 10; //Length of array

int temp = 0; // create a temporal variable

for(int i=0; i < n; i++){

for(int j=1; j < (n-i); j++){

if(arr[j-1] > arr[j]){

// The bubble sort algorithm swaps elements

temp = arr[j-1];

arr[j-1] = arr[j];

arr[j] = temp;

}

public static void main(String[] args) {

//declaring the array of integers

int [] array = new int[10];

//Prompt user to add elements into the array

Scanner in = new Scanner(System.in);

//Use for loop to receive all 10 elements

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

System.out.println("Enter the next array Element");

array[i] = in.nextInt();

}

//Print the array elements before bubble sort

System.out.println("The Array before bubble sort");

System.out.println(Arrays.toString(array));

//Call bubble sort method

bb_Sort(array);

System.out.println("Array After Bubble Sort");

System.out.println(Arrays.toString(array));

Our favorite program runs in 10 seconds on computer A, which has a 2 GHz clock. We are trying to help a computer designer build a computer, B, which will run this program in 6 seconds. The designer has determined that a substantial increase in the clock rate is possible, but this increase will affect the rest of the CPU design, causing computer B to require 1.2 times as many clock cycles as computer A for this program. What clock rate should we tell the designer to target?

Answers

Clock rate is simply the number of clock cycles a computer can perform in a second

Computer B should be designed to have a clock rate of 4GHz

The given parameters are:

$\mathbf{t_A = 10s}$ --- time on computer A

$\mathbf{c_A = 2GHz}$ --- computer A clock

$\mathbf{t_B = 6s}$ --- time on computer B

Start by calculating the period of computer A

$\mathbf{T_A = (1)/(c_A)}$

So, we have:

$\mathbf{T_A = (1)/(2GHz)}$

Rewrite as:

$\mathbf{T_A = (1)/(2 * 10^9 Hz)}$

So, we have:

$\mathbf{T_A = 0.5 * 10^(-9) s}}$

Next, we calculate the required number of clocks on computer A

$\mathbf{n_A = (t_A)/(T_A)}$

So, we have:

$\mathbf{n_A = (10)/(0.5 * 10^(-9))}$

$\mathbf{n_A = 20 * 10^(9)}$

Computer B requires 1.2 times as many clock cycles as A.

So, we have:

$\mathbf{n_B = 1.2 * n_A}$

This gives

$\mathbf{n_B =1.2 * 20 * 10^(9)}$

$\mathbf{n_B =24 * 10^(9)}$

The clock period of computer B is:

$\mathbf{T_B = (t_B)/(n_B)}$

So, we have:

$\mathbf{T_B = (6)/(24 * 10^(9))}$

$\mathbf{T_B = 0.25 * 10^(-9)}$

Lastly, the clock rate of computer B is:

$\mathbf{c_B = (1)/(T_B)}$

$\mathbf{c_B = (1)/(0.25 * 10^(-9))}$

$\mathbf{c_B = 4 * 10^(9)}$

Express in gigahertz

$\mathbf{c_B = 4 GHz}$

Hence, computer B should be designed to have a clock rate of 4GHz

. A file allocation table (FAT) is used to keep track of the portions assigned to a file. Select one: True False

Answers

Answer: True

Explanation: File allocation table(FAT) is the part of the file system that helps the hard drives .It is used for the management of the files and data which gets stored in the hard drive by the operating system. It can also help in the extension or expansion of the hard drive storage.

It also keeps tracing the files and data accordingly. This table works for the portable devices ,cameras etc. Thus, the statement given is true.

The advantages of automation include: (I) reduced output variability. (II) reduced variable costs. (III) machines don't strike or file grievances. (IV) machines are always less expensive than human labor.

Answers

Answer:

(III) machines don't strike or file grievances.

(IV) machines are always less expensive than human labor.

Explanation:

The advantage of automation among the option is:

(III) machines don't strike or file grievances - Machine has the advantage of not going on strike or filing grievances. It just obey instruction. Strike are human way of showing grievances. With automation, there is no issue of strike or filing for grievance.

(IV) machines are always less expensive than human labor - Machines as a means of automation are very cheap when compared to human labor. The only added cost for machine is the added cost after the cost of purchase. For human labor, the cost is not fixed or predictable.

Write a program that reads a string (password) and a number. The program will keep asking the user for a password and number as long as the user does not provide the expected values ("milkyway" and 1847, respectively), and as long as the user has not exhausted the maximum number of attempts . In addition, the program will stop asking for data if the word "quit" is provided as a password value (in this case, the program will not read the number). The program will print the message "Wrong credentials" when an invalid password or number (or both) is provided. If the user eventually provides the correct credentials the message "Access Granted" will be displayed; otherwise the message "Access Denied" will be generated. The following example illustrates the messages to use to read data and to display results. Enter password: milkyway Enter number: 10 Wrong credentials Enter password: tomato Enter number: 1847 Wrong credentials Enter password: milkyway Enter number: 1847 Access Granted
