Answer: Worm

Explanation: Worm is the malicious software program which acts as the infection in the computer system. It has the ability to replicate itself and spread in the other systems .It is found in those parts that have automatic operation and non-noticeable.

The effect of the worm is slowing down the operations ,disturb the network etc.Other options are incorrect because virus is the malicious program that infects the host, key-loggers are used for monitoring of system and  time bomb is the program for releasing the virus in computer network.

In this project you will write a set of instructions (algorithm). The two grids below have colored boxes in different locations. You will create instructions to move the colored boxes in grid one to their final location in grid two. Use the example to help you. The algorithm that you will write should be in everyday language (no pseudocode or programming language). Write your instructions at the bottom of the page.Example: 1. Move the orange box 2 spaces to the right.2. Move the green box one space down. 3. Move the green box two spaces to the left.Write your instructions. Review the rubric to check your final work.Rules: All 6 colors (red, green, yellow, pink, blue, purple) must be move to their new location on the grid. Block spaces arebarriers. You cannot move through them or on them – you must move around them

(Display nonduplicate words in ascending order)Write a program that prompts the user to enter a text in one line and displays all the nonduplicate words in ascending order.
Sample Run
Enter a text: Good morning Good afternoon Good evening
Good afternoon evening morning

Answers

The programreturns uniqueelements in the string passed in with no duplicates. The programis written in python 3 thus :

text = input('Enter text : ')

#promptsuserto enterstring inputs

split_text = text.split()

#splitinputtedtext basedonwhitespace

unique = set(split_text)

#usingtheset function,takeonlyuniqueelementsin thestring

combine = ' '.join(unique)

#usethejoinfunctiontocombinethestringstoformasingle lengthstring.

Answer:

The program to this question as follows:

Program:  

value = input("Input text value: ") #defining variable value and input value by user

word = value.split() #defining variable word that split value

sort_word = sorted(word) #defining variable using sorted function

unique_word = [] #defining list

for word in sort_word: #loop for matching same value

   if word not in unique_word: #checking value

       unique_word.append(word) #arrange value using append function

print(' '.join(unique_word)) #print value

Output:

Input text value: Good morning Good afternoon Good evening

Good afternoon evening morning  

Explanation:

In the above python code, a value variable is defined that uses input function to input value from the user end, and the word variable is declared, which uses the split method, which split all string values and defines the sort_word method that sorted value in ascending order.

  • Then an empty list "unique_word" is defined, which uses the for loop and inside the loop, a conditional statement is used.
  • In if block, it matches all value is unique if this is condition is true it will arrange all values and uses the print function to print all value.  

Write a class named Episode. An instance of this episode class will represent a single episode of a TV show, with a title, a season number, and an episode number. For example "Friends, season 1, episode 1", or "The Wire, season 3, episode 5." Your class should have the following constructors and methods: A constructor that accepts three arguments: a String for the title, an int for the season number, and an int for the episode number. A constructor that accepts only a String, for the title, and sets the season and episode numbers to 1. A setter and getter for the title. (never mind the season and episode numbers.) A method named "equals", that accepts an Episode, and returns true if the title, season number and episode number are the same as the receiving object's. A method named "comesBefore". This method should also accept an Episode. It should return true if the episode that receives the invocation comes before the parameter. That is only true if the two objects have the same title, and if the argument comes from a later season, or the same season, but a later episode. Write only the class. Do not write a whole program

this.title = title;

this.seasonNumber = seasonNumber;

//Getter and setters

public void setEpisodeNumber(int episodeNumber) {

this.episodeNumber = episodeNumber;

}

public boolean comesBefore(Episode e){

//Check if titles' match

g Write a line of code to invoke a function named RandNum, which accepts no parameters, and storing the return value in a variable called num (which has already been defined). Separate each item with 1 space (except around the parentheses), and end the line with a semi-colon.

Answers

Answer:

public int RandNum();

* Assuming it returns an integer

Explanation:

I believe you mean to write the function header of randNum.

To write the header of the function, we need to specify its return type, name, parenthesis and parameters inside the parenthesis - if exist.

If it returns an integer it should have int, if it returns a double it should have double in the header. In the answer, I assumed it returns an integer.

The name is already given, RandNum

Since, the function does not take any parameter, inside of the parenthesis will be empty.
