Answer:

c, d and e.

Explanation:

An algorithm is a step by step procedure

in solving a particular problem. An algorithm is finite - it has a beginning and an end.

With the options provided;

* option a is not an algorithm, though it describes the tool to solving a problem, it does not specify the steps involved in solving the problem.

* option b is also not an algorithm because it only shows a list of favorite animals and that is solving no problem.

* option c is also an algorithm. An algorithm solves a problem by providing steps to solving it. A problem statement describes the problem, and the steps on how to solve the problem.

* option d is an algorithm. Setting up the new DVD player is the problem. Steps for setting it up are shown in the instructions. Therefore, since a problem will be solved by following those instructions, that option is an algorithm.

* option e is also an algorithm. Moving a lighting bot around to turn on the lights is the problem. How this is solved are shown in the series of steps. This makes option e and algorithm.

Answer:

A. The mathematical formula for finding the area of a circle.

D. Instructions for setting up a new DVD player

E. A series of steps that moves a "lighting bot" around to turns on lights.

Explanation:

Algorithm is a systematic procedure (or process) that produces the answer to a question or the solution of a problem in a finite number of steps.

Option A is an algorithm. The mathematical formula for finding the area of a circle gives a solution to a problem. The problem is finding area of a circle and the formula gives the step by step procedure finding the area of a circle.

Option B is not an algorithm. Option B just provide a list of your favourite animals and it doesn't answer a question we know about.

Option C is not an algorithm. A problem statement is still a problem with no solution whereas algorithm provides solution

Option D is an algorithm. It provides the step by step procedures for setting up a new DVD player

Option E is an algorithm. It provides a series of steps that moves a lighting bot around to turns on lights, so it provides a solution.

In public-key encryption, the two keys–one for coding and one for decoding–are known as ________.

Feliz [49]

Public key and private key - In public key encryption, a pair of keys is used (public key and private key). The public key can be made available publicly, while the private key is only known by the owner. The public key is used to encrypt the message, while the private key is used to decrypt the message.

Write a second constructor as indicated. Sample output: User1: Minutes: 0, Messages: 0 User2: Minutes: 1000, Messages: 5000

Mashcka [7]

Complete Question:

Write a second constructor as indicated. Sample output:User1: Minutes: 0, Messages: 0User2: Minutes: 1000, Messages: 5000// ===== Code from file PhonePlan.java =====public class PhonePlan { private int freeMinutes; private int freeMessages; public PhonePlan() { freeMinutes = 0; freeMessages = 0; } // FIXME: Create a second constructor with numMinutes and numMessages parameters. /* Your solution goes here */ public void print() { System.out.println("Minutes: " + freeMinutes + ", Messages: " + freeMessages); return; }}

Answer:

The second constructor is given as:

//This defines the constructor, the name has to be the same as the class //name

PhonePlan(int numOfMinutes, int numberOfMessages) {

this.freeMinutes = numOfMinutes;

this.freeMessages = numberOfMessages

}

Explanation:

The second constructor is defined using java programming language.

The given class has two constructors This is called "Constructor Overloading) which implements polymophism
In the second constructor that we created, we pass in two arguments of type integer numOfMinutes and numberOfMessages.
In the constructor's body we assign these values to the initially declared variables freeMinutes and freeMessages

Charlie has a large book collection. He was keeping track of it in a spreadsheet, but it has grown big enough that he wants to c

zepelin [54]

Answer:

Check the explanation

Explanation:

Ans 1) storing the data in one single row comes with its own barriers and that is if you delete one of the record in the spreadsheet, all the equivalent records which you didn't wanted to delete would be deleted. For take for instance, if you wish to delete the record of author "James Taylor" then all the books he has written would also be deleted from the spreadsheet.

Ans 2) In 1NF, all row is expected to have only 1 tuple, but here in this spreadsheet the title field for Author "James Taylor" has 2 books, so it would be separated into single rows.

Ans 3) The table in the attached image below doesn't delete with Delete anomaly, i.e., for author "May Norton" if you delete this record, then the only book written by her would be deleted.

So, you have to convert this table into 2NF.

Make separate tables for Author and Book

Author(Author Name, Author Country)

Books(Author Name, Book title, Publisher, Publisher Location, Year, price)

This cannot be normalized any further.

Write a public static method named printArray, that takes two arguments. The first argument is an Array of int and the second ar

Serjik [45]

Answer:

Written in Java

public static void printArray(int myarr[], String s){

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

System.out.print(myarr[i]+s);

}

Explanation:

This defines the static method alongside the array and the string variable

public static void printArray(int myarr[], String s){

The following iteration iterates through the elements of the array

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

This line prints each element of the array followed by the string literal

System.out.print(myarr[i]+s);

}

The method can be called from main using:

<em>printArray(myarr,s);</em>

Where myarr and s are local variables of the main
