Answer:
The function in Python is as follows:
def search_file(filename,mystring):
my_dict = {}
count = 0
file = open(filename)
lines = file.readlines()
for line in lines:
count+=1
if mystring.lower() in line.lower():
my_dict[count] = line.rstrip('\n')
return my_dict
Explanation:
This defines the function
def search_file(filename,mystring):
This initializes an empty dictionary
my_dict = {}
This initializes the number of lines to 0
count = 0
This opens the file
file = open(filename)
This reads the lines of the file
lines = file.readlines()
This iterates through the lines
for line in lines:
This increments the number line
count+=1
This checks if the string exists in the line
if mystring.lower() in line.lower():
If yes, the line number and the string are added to the dictionary
my_dict[count] = line.rstrip('\n')
This returns the dictionary
return my_dict
Which of the following statements is TRUE of a peer-to-peer network?
A. Different parties have very different opinions on what can and can’t be shared through a peer-to-peer network.
B. In a peer-to-peer network, all files being shared are kept on one server. Anyone who wants to access one of those files can get it directly from the server.
C. A peer-to-peer network can create heavy traffic and makes download times increase significantly.
D. Creating a directory of which computers have certain files is an acceptable practice.
Answer:
A. Different parties have very different opinions on what can and can’t be shared through a peer-to-peer network.
Explanation:
CORRECT
Choice 'A' is very true. There have been many arguments and court cases over what content can and cannot be shared through a peer-to-peer network. Users of these networks often argue that free speech allows us to share whatever we want online. Content creators on the other hand frequently sue for copyright infringement.
INCORRECT
Choice 'B' is describing a centralized system, not a peer-to-peer network. In a peer-to-peer network, there is no central location of files. Files are transferred directly from one computer to another without a middleman.
Choice 'C' is also not true of peer-to-peer networks. These networks are actually much more efficient than centralized systems because there is no large server holding all the files. It takes less time to download files from a peer-to-peer network because there is no centralized source of information and files.
Choice 'D' is also false; this was decided in the court case about Napster, one of the first large peer-to-peer networks. Having a centralized directory of who has which files is not considered free speech.
The peer-to-peer network is said to have varying views that form the basis of what can and cannot be shared. Thus, option A is correct.
What is a peer-to-peer network?A peer-to-peer network is given as the connection of the computers that are linked with the following same responsibilities and permissions.
The network is said to have varying views. Many debates and court cases have erupted over what content can and cannot be shared over a peer-to-peer network.
Users of these sites frequently argue that freedom of speech allows us to share whatever we want on the internet.On the other hand, content creators frequently file copyright infringement lawsuits.Thus, option A is correct.

Write a program that prints the sum of the even numbers and the products of odd numbers on the screen
Answer:
The program in Python is as follows:
n = int(input("Number of inputs: "))
total = 0; product = 1
for i in range(n):
num = int(input(": "))
if num%2 == 0:
total+=num
else:
product*=num
print("Sum of even: ",total)
print("Product of odd: ",product)
Explanation:
This prompts the user for the number of inputs, n
n = int(input("Number of inputs: "))
This initializes sum (total) to 0 and products to 1
total = 0; product = 1
This iterates through n
for i in range(n):
This gets the inputs
num = int(input(": "))
If input is even, calculate the sum
if num%2 == 0:
total+=num
If otherwise, calculate the product
else:
product*=num
Print the required outputs
print("Sum of even: ",total)
print("Product of odd: ",product)

Create a class named TriviaGameV1 that plays a simple trivia game. The game should have five questions. Each question has a corresponding answer and point value between 1 and 3 based on the difficulty of the question. TriviaGameV1 will use three arrays. An array of type String should be used for the questions. Another array of type String should be used to store the answers. An array of type int should be used for the point values. All three arrays should be declared to be of size 5. The index into the three arrays can be used to tie the question, answer, and point value together. For example, the item at index 0 for each array would correspond to question 1, answer 1, and the point value for question 1. Manually hardcode the five questions, answers, and point values in the constructor of TriviaGameV1. The five questions and their corresponding answers are shown on page 3. The point values should be set to 1, 2, 2, 3, 1, respectively.
The class should also provide the following two public methods:
• public boolean askNextQuestion() - This method takes no argument and returns a boolean. If there are no more questions to ask, it returns false. Otherwise, it asks the next question and gets an answer from the user. If the player’s answer matches the actual answer (case insensitive comparison), the player wins the number of points for that question. If the player’s answer is incorrect, the player wins no points for the question and the method will show the correct answer. It returns true after Q & A have been processed.
• public void showScore() - This method takes no argument and returns void. It displays the current score the player receives thus far.
The test driver is provided below, which creates a TriviaGameV1 object. After the player has answered all five questions, the game is over.
public class TriviaGameV1Test {
public static void main(String[] args) { TriviaGameV1 game = new TriviaGameV1();
while (game.askNextQuestion()) game.showScore(); System.out.println("Game over! Thanks for playing!"); }
}
Answer:
Explanation:
The following code is written in Java, It creates the class for the Trivia game along with the arrays, variables, and methods as requested so that it works flawlessly with the provided main method/test driver. The attached picture shows the output of the code.

Your systems analysis team is close to completing a system for Azuka Theatre. Kevin is quite con- fident that the programs he has written for Azuka's inventory system used for keeping track of stage scenery and props will perform as required because they are similar to programs he has done before. Your team has been very busy and would ideally like to begin full systems testing as soon as possible. Mark and Allison, two of your junior team members have proposed the following:
a. Skip desk checking of the programs (because similar programs were checked in other installa- tions; Kevin has agreed).
b. Do link testing with large amounts of data to prove that the system will work.
c. Do full systems testing with large amounts of live data to show that the system is working. Respond to each of the three steps in their proposed test schedule. Use a paragraph to explain your response.

Desk checking is a method to check the logic of an algorithm by manually working through it. There are many reasons for Desk Checking that may be omitted or simplified.
What are the reasons for desk checking?If the current program’s logic is identical, then this step may be omitted; this, however, implies some effort to verify “sameness.” If truly identical, perhaps there is re-usable code, or the code to be developed should become a reusable library routine.
Link testing is the testing of the group of modules in order to ensure that the modules operate correctly in combination. It generally verifies that the function or operation is executed properly. System testing is a type of testing that is used to confirm the actual function of the system in which a work is executed or performed.
Therefore, all of the testing mechanisms are well described above.

You are an IT network administrator at XYZ Limited. Your company has critical applications running of its Ubuntu Linux server. Canonical, the company that owns and maintains Ubuntu just releases an update to patch a security vulnerability in the system.
Required:
What BEST action you should take?
Answer:
Explanation:
I believe that the best course of action would be to divide the companies computers and run the critical applications on half of the systems while the other half update to the latest Ubuntu release. Once that half is done updating, you run the applications on the updated systems and update the other half of the systems. This will allow the company to continue its operations without any downtime, while also updating to the latest Ubuntu release on all systems and making sure that all systems do not have any security vulnerabilities due to outdated software.

Transportation, carrying
Warehousing, labour
Answer: Set-up costs, carrying costs
Explanation:
When it comes to production, the goal is to produce with as little costs as possible so that more profit can be made when the goods are sold.
This is why the Economic Batch Quantity is important. It shows the maximum amount of goods that can be produced in a particular production run such that costs will be minimized.
As such, it is based on the set-up costs of production for that run as well as the carrying costs through the run.

Using recursion, write a program that asks a user to enter the starting coordinates (row, then column), the ending coordinates (row then column), and calculates the number of paths from the starting coordinate to the ending coordinate.
Answer:
The program in Python is as follows
def Paths(row,col):
if row ==0 or col==0:
return 1
return (Paths(row-1, col) + Paths(row, col-1))
row = int(input("Row: "))
col = int(input("Column: "))
print("Paths: ", Paths(row,col))
Explanation:
This defines the function
def Paths(row,col):
If row or column is 0, the function returns 1
if row ==0 or col==0:
return 1
This calls the function recursively, as long as row and col are greater than 1
return (Paths(row-1, col) + Paths(row, col-1))
The main begins here
This prompts the user for rows
row = int(input("Row: "))
This prompts the user for columns
col = int(input("Column: "))
This calls the Paths function and prints the number of paths
print("Paths: ", Paths(row,col))
Write a program that randomly (using the random number generator) picks gift card winners from a list of customers (every customer has a numeric ID) who completed a survey. After the winning numbers are picked, customers can check if they are one of the gift card winners. In your main function, declare an integer array of size 10 to hold the winning customer IDs (10 winners are picked). Pass the array or other variables as needed to the functions you write. For each step below, decide what arguments need to be passed to the function. Then add a function prototype before the main function, a function call in the main function and the function definition after the main function.
Answer:
Explanation:
Since no customer ID information was provided, after a quick online search I found a similar problem which indicates that the ID's are three digit numbers between 100 and 999. Therefore, the Java code I created randomly selects 10 three digit numbers IDs and places them in an array of winners which is later printed to the screen. I have created an interface, main method call, and method definition as requested. The picture attached below shows the output.
import java.util.Random;
interface generateWinner {
public int[] winners();
}
class Brainly implements generateWinner{
public static void main(String[] args) {
Brainly brainly = new Brainly();
int[] winners = brainly.winners();
System.out.print("Winners: ");
for (int x:winners) {
System.out.print(x + ", ");
}
}
public int[] winners() {
Random ran = new Random();
int[] arr = new int[10];
for (int x = 0; x < arr.length; x++) {
arr[x] = ran.nextInt(899) + 100;
}
return arr;
}

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. g
Answer:
The program in Python is as follows:
string = input("String: ")
chr = input("Character: ")[0]
total_count = string.count(chr)
print(total_count,end=" ")
if total_count > 1:
print(chr+"'s")
else:
print(chr)
Explanation:
This gets the string from the user
string = input("String: ")
This gets the character from the user
chr = input("Character: ")[0]
This counts the occurrence of the character in the string
total_count = string.count(chr)
This prints the total count of characters
print(total_count,end=" ")
If the count is greater than 1
if total_count > 1:
Then it prints a plural form
print(chr+"'s")
If otherwise
else:
Then it prints a singular form
print(chr)
