Create a class called Palindromes, which will determine if a user’s entry is a palindrome. A
palindrome is a word or phrase that reads the same backwards or forwards. See the examples.
A Santa at NASA My gym taco cat kayak NOW I WON race car
Your program will ignore spaces and ignore case when determining if a string is a palindrome.
Use the String method replace to remove the spaces. If it is a palindrome, output
PALINDROME, or else output NOT PALINDROME.
Additional requirements:
 Add an infinite loop with a sentinel-trigger break test (allowing them to input multiple
attempts). You may decide on its command word or exit-condition.
 As below, make sure a spacer line exists between each run of the program
Here are two sample runs of the program.
Enter a word or phrase: Noon
PALINDROME
Enter a word or phrase: bookkeeper
NOT PALINDROME

Answer 1

Answer:

import java.util.Scanner;

class Main {

 public static void main(String[] args) {

   test("A Santa at NASA");

   test("My gym");

   test("taco cat");

   test("kayak");

   test("NOW I WON");

   test("race car");

   test("bookkeeper");

   Scanner scanner = new Scanner(System.in);

   

   while(true) {

     System.out.print("Enter a word or phrase: ");

     String line = scanner.nextLine();

     if (line.equals("exit")) break;

     if (Palindromes.isPalindrome(line)) {

       System.out.println("PALINDROME");

     } else {

       System.out.println("NOT PALINDROME");

     }

   }

   scanner.close();

 }

 public static void test(String s) {

   System.out.printf("'%s' is %sa palindrome\n", s, Palindromes.isPalindrome(s) ? "" : "not ");

 }

}

class Palindromes {

 static boolean isPalindrome(String s) {

   s = s.replaceAll("\\s","").toLowerCase();

   return s.equals(reverseString(s));

 }

   public static String reverseString(String str){  

     StringBuilder sb = new StringBuilder(str);  

     sb.reverse();  

     return sb.toString();  

 }  

}

Explanation:

I chose to use a string reverse routine. This is slightly less efficient than iterating the string from both ends, but performance is less important than readability here.

The stop word is exit.

Discuss the core technologies and provide examples of where they exist in society. Discuss how the core technologies are part of a larger system

Answers

Answer:

Part A

The core technologies are the technologies which make other technologies work or perform their desired tasks

Examples of core technologies and where they exist are;

Thermal technology, which is the technology involving the work production, storage, and transfer using heat energy, exists in our refrigerators, heat engine, and boilers

Electronic technology is the technology that involves the control of the flow of electrons in a circuit through rectification and amplification provided by active devices. Electronic technology can be located in a radio receiver, printed circuit boards (PCB), and mobile phone

Fluid technology is the use of fluid to transmit a force, provide mechanical advantage, and generate power. Fluid technologies can be found in brakes, automatic transmission systems, landing gears, servomechanisms, and pneumatic tools such as syringes

Part B

The core technologies are the subsystems within the larger systems that make the larger systems to work

The thermal technology in a refrigerator makes use of the transfer of heat from a cold region, inside the fridge, to region of higher temperature, by the  use of heat exchange and the properties of the coolant when subjected to different amount of compression and expansion

The electronic technologies make it possible to make portable electronic devises such as the mobile phones by the use miniaturized circuit boards that perform several functions and are integrated into a small piece of semiconductor material

Fluid technologies in landing gears provide reliable activation of the undercarriage at all times in almost all conditions such that the landing gears can be activated mechanically without the need for other source of energy

Explanation:

Core technologies includes biotechnology, electrical, electronics, fluid, material, mechanical, and others.

What are core technologies?

Core Technologies are known to be the framework of technology systems. The major Core Technologies includes:

Mechanical StructuralMaterials, etc.

They are also called "building blocks" of all technology system as without time, technology would not be existing today.

Write a program that accepts an integer value called multiplier as user input. Create an array of integers with ARRAY_SIZE elements. This constant has been declared for you in main, and you should leave it in main. Set each array element to the value i*multiplier, where i is the element's index. Next create two functions, called PrintForward() and PrintBackward(), that each accept two parameters: (a) the array to print, (b) the size of the array. The PrintForward() function should print each integer in the array, beginning with index 0. The PrintBackward() function should print the array in reverse order, beginning with the last element in the array and concluding with the element at index 0. (Hint: for help passing an array as a function parameter, see zybooks section 6.23) As output, print the array once forward and once backward.

Answers

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

void PrintForward(int myarray[], int size){

   for(int i = 0; i<size;i++){        cout<<myarray[i]<<" ";    }

}

void PrintBackward(int myarray[], int size){

   for(int i = size-1; i>=0;i--){        cout<<myarray[i]<<" ";    }

}

int main(){

   const int ARRAY_SIZE = 12;

   int multiplier;

   cout<<"Multiplier: ";

   cin>>multiplier;

   int myarray [ARRAY_SIZE];

   for(int i = 0; i<ARRAY_SIZE;i++){        myarray[i] = i * multiplier;    }

   PrintForward(myarray,ARRAY_SIZE);

   PrintBackward(myarray,ARRAY_SIZE);

   return 0;}

Explanation:

The PrintForward function begins here

void PrintForward(int myarray[], int size){

This iterates through the array in ascending order and print each array element

   for(int i = 0; i<size;i++){        cout<<myarray[i]<<" ";    }

}

The PrintBackward function begins here

void PrintBackward(int myarray[], int size){

This iterates through the array in descending order and print each array element

   for(int i = size-1; i>=0;i--){        cout<<myarray[i]<<" ";    }

}

The main begins here

int main(){

This declares and initializes the array size

   const int ARRAY_SIZE = 12;

This declares the multiplier as an integer

   int multiplier;

This gets input for the multiplier

   cout<<"Multiplier: ";    cin>>multiplier;

This declares the array

   int myarray [ARRAY_SIZE];

This iterates through the array and populate the array by i * multiplier

   for(int i = 0; i<ARRAY_SIZE;i++){        myarray[i] = i * multiplier;    }

This calls the PrintForward method

   PrintForward(myarray,ARRAY_SIZE);

This calls the PrintBackward method

   PrintBackward(myarray,ARRAY_SIZE);

   return 0;}

Explanation:

One of the disadvantages of cable technology is that systems used by many providers require customers to share bandwidth with neighbors. This ultimately causes many problems since cables would need to be extended to reach every single user that will be sharing the bandwidth. This would mean cables all over the place. Also, it is very difficult to limit the bandwidth per person, meaning that if anyone is using up all of the bandwidth through the cable, the rest of the individuals connected would not have the bandwidth that they need or are paying for.

Explanation:

The option that doesn't cause accumulation of big data is that Law enforcement officials request the driver's license history for a suspect they recently apprehended.

What causes accumulation of data?

Data is an information that is processed by a computer and can be stored in the computer for future use or reference purposes.

The quantity of data processed by a computer depends on the volume of the raw data that is collected and prepared before processing takes place.

From the given options;

Law enforcement officials request the driver's license history for a suspect they recently apprehended. This is just the data of a single individual which can not cause big data accumulation.

Receivers in cell phones request position information from nearby cell phone towers, and this location information is communicated to cell phone companies. This involves more that one cell phone company therefore can cause accumulation of big data.
