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.
Answers
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;
}
}

SMTP (Simple Mail Transfer Protocol) is the standard protocol for transferring mail between hosts over TCP. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. Suppose you wish to build a packet filter rule set allowing inbound and outbound SMTP traffic. You generate the following rule set:
Rule Direction Src Addr Dest Addr Protocol Dest Port Action
A In External Internal TCP 25 Permit
B Out Internal External TCP >1023 Permit
C Out Internal External TCP 25 Permit
D In External Internal TCP >1023 Permit
E Either Any Any Any Any Deny
Required:
Describe the effect of each rule.
Answers
Answer:
The five rules are described as follows:
Rule A permits the inbound Simple Mail Transfer Protocol (SMTP) connection.
Rule B permits the inbound Simple Mail Transfer Protocol (SMTP) connection.
Rule C permits the outbound Simple Mail Transfer Protocol (SMTP) connection.
Rule D permits the outbound Simple Mail Transfer Protocol (SMTP) connection.
Rule E does not perform any action. Thus it is when the action is denied.
Explanation:
Rule A allows information transfer of the incoming email from the external server to the internal remote server, thus this allows an inbound connection.
Rule B allows information transfer of the incoming email from the remote server to the external remote server, thus this allows an inbound connection.
Rule C allows information transfer of outgoing email from the external server to the internal remote server, thus this allows an outbound connection.
Rule D allows information transfer of the outgoing email from the remote server to the external remote server, thus this allows an outbound connection.
Rule E does not allow any action in either direction thus it is when action is denied.
Design a Python3 function to compare every prefix of a string X to every element of string Y, if there is a match, place it in a python set, sort and reversely sort the set, and return the sorted and reversely sorted sets.
Answers
Answer:
The function is as follows:
def compare_prefix(strX,strY):
prefix=set()
for i in range(len(strX)):
for j in range(i+1,len(strX)):
chk =strX[i:j+1]
if chk in strY:
prefix.add(chk)
sort_prefix = sorted(prefix)
rev_sort_prefix = sorted(prefix,reverse=True)
return(sort_prefix,rev_sort_prefix)
Explanation:
This defines the function
def compare_prefix(strX,strY):
This creates an empty set, prefix
prefix=set()
This iterates through each character in strX
for i in range(len(strX)):
This iterates through every other character in strX
for j in range(i+1,len(strX)):
This gets the prefix of strX by concatenating strings from i to j + 1
chk =strX[i:j+1]
This checks if the prefix is in strY
if chk in strY:
If yes, the string is added to set prefix
prefix.add(chk)
This sorts prefix
sort_prefix = sorted(prefix)
This reverses the sorted prefix
rev_sort_prefix = sorted(prefix,reverse=True)
This returns the sorted and reversed prefix
return(sort_prefix,rev_sort_prefix)

Write a program that lets a maker of chips and salsa keep track of sales for five different types of salsa: mild, medium, sweet, hot, and zesty. The program should use two parallel 5-element arrays: an array of strings that holds the five salsa names and an array of integers that holds the number of jars sold during the past month for each salsa type. The salsa names should be stored using an initialization list at the time the name array is created. The program should prompt the user to enter the number of jars sold for each type. Once this sales data has been entered, the program should produce a report that displays sales for each salsa type, total sales, and the names of the highest selling and lowest selling products.
Answers
Answer:
The program in Java is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String [] salsa = {"Mild","Medium","Sweet","Hot","Zesty"};
int [] number = new int[5];
for(int i = 0;i<5;i++){
System.out.print(salsa[i]+" number: ");
number[i] = input.nextInt();
}
for(int i = 0;i<5;i++){
System.out.println(salsa[i]+" : "+number[i]);
}
int smallest = number[0]; int highest = number[0];
int count = 0;
for(int i = 0;i<5;i++){
if(smallest > number[i]){
smallest = number[i];
count = i;
}
}
System.out.println("Smallest");
System.out.println(salsa[count]+" : "+smallest);
for(int i = 0;i<5;i++){
if(highest < number[i]){
highest = number[i];
count = i;
}
}
System.out.println("Highest");
System.out.println(salsa[count]+" : "+highest);
}
}
Explanation:
This initializes the salsa names
String [] salsa = {"Mild","Medium","Sweet","Hot","Zesty"};
This declares the array for the amount of salsa
int [] number = new int[5];
This iterates through the 5 salsas and get input for the amount of each
for(int i = 0;i<5;i++){
System.out.print(salsa[i]+" number: ");
number[i] = input.nextInt();
}
This prints each salsa and the amount sold
for(int i = 0;i<5;i++){
System.out.println(salsa[i]+" : "+number[i]);
}
This initializes smallest and largest to the first array element
int smallest = number[0]; int highest = number[0];
This initializes the index of the highest or lowest to 0
int count = 0;
The following iteration gets the smallest of the array elements
for(int i = 0;i<5;i++){
if(smallest > number[i]){
smallest = number[i];
This gets the index of the smallest
count = i;
}
}
This prints the smallest
System.out.println("Smallest");
System.out.println(salsa[count]+" : "+smallest);
The following iteration gets the largest of the array elements
for(int i = 0;i<5;i++){
if(highest < number[i]){
highest = number[i];
This gets the index of the highest
count = i;
}
}
This prints the highest
System.out.println("Highest");
System.out.println(salsa[count]+" : "+highest);
Your systems analysis team is close to completing a system for Azuka Theatre.

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.

Explanation:
There used to be a popular type of pulp book for younger readers. They were called "Choose Your Own Adventure" novels. The idea was pretty simple. You'd start reading and then a few pages into the book, there would be a plot development that required a choice. The book might describe that you've entered a spooky house and the door has locked behind you. It would then ask you if you want to try to exit by going through the kitchen or exploring upstairs. If you chose to go into the kitchen, you'd turn to page 200, if you chose to go upstairs, you'd turn to page 43. This would repeat maybe five or six times though the book. You could re-read it a few times and try different outcomes.
In this lab you are going to create a choose your own adventure application using navigation controllers. The introduction screen to your application will contain a few lines of text to set up a story and then leave the user with a choice. Below the text, you will present two buttons that correspond to the different choices.
For example, you might see the following text on the main screen:
You are walking down the street when a tiger runs up and takes your lunch and then runs away...
Do you want to chase the tiger or run away?
Chase
Run Away
The user must then tap one of the buttons. This will move the user to a new screen with a few more lines of the story and another choice and two more buttons. You will create three (3) turning points in your story. This means that your story will have eight (8) different possible outcomes and a total of 15 screens.
Requirements
The story must ask three (3) questions, no matter how the user answers the previous question. All the questions must be different and result in a different story text.
The story must have eight (8) possible different final outcomes.
The story must include a minimum of 15 screens in total.
Create content that is appropriate and not-offensive. We will share these and play them together.
For extra credit you can add an extra screen and use inputs to capture data from the user such as a name, favorite food, or lucky number and use this data in the story.

Which statement best describes Link State routing? Group of answer choices Each router builds a cost-weighted graph of the network of all the routers and the shortest links between them, based on information received from each router regarding only its nearest neighbors All of these Each router uses a HELLO packet to announce its presence to its neighbors Each router builds a table with the best distance between each router and the link to use, based on each router’s providing data on distances to all the routers in its routing table to its nearest neighbors
Answers
Answer:
Each router builds a cost-weighted graph of the network of all the routers and the shortest links between them, based on information received from each router regarding only its nearest neighbors.
Explanation:
A routing protocol can be defined as a set of defined rules or algorithms used by routers to determine the communication paths unto which data should be exchanged between the source router and destination or host device.
Additionally, in order for packets to be sent to a remote destination, these three parameters must be configured on a host.
I. Default gateway
II. IP address
III. Subnet mask
After a router successfully determines the destination network, the router checks the routing table for the resulting destination network number. If a match is found, the interface associated with the network number receives the packets. Else, the default gateway configured is used. Also, If there is no default gateway, the packet is dropped.
Basically, there are two (2) main categories of routing protocols used in packet switching networks and these includes;
1. Distance-vector routing.
2. Link state routing.
Link state routing refers to a complex routing technique in which each router learns about it's own neighborhood or directly connected networks (links) and shares the information with every other router present in the network.
Hence, the statement which best describes Link State routing is that, each router builds a cost-weighted graph of the network of all the routers and the shortest links between them, based on information received from each router regarding only its nearest neighbors. Some examples are intermediate system to intermediate system (IS-IS) and open shortest path first (OSPF).
Write a Perl program that uses a hash and a large number of operations on the hash. For example, the hash could store people’s names and their ages. A random- number generator could be used to create three- character names and ages, which could be added to the hash. When a duplicate name was generated, it would cause an access to the hash but not add a new element. Rewrite the same program without using hashes. Compare the execution efficiency of the two. Compare the ease of programming and readability of the two.

The Perl code is attached in the attachment. The execution time for using hashes is 0 seconds while that for without hash is 27 seconds.
Explanation:
In terms of ease of access and readability, both approaches are similar. However, it is evident from the time of execution that the with hashes is more efficient than the value of without hashes. This indicates that using hashes is more efficient.

The following code segment appears in a class other than Backyard. It is intended to print true if b1 and b2 have the same lengths and widths, and to print false otherwise. Assume that x, y, j, and k are properly declared and initialized variables of type int.
Backyard b1 = new Backyard(x, y);
Backyard b2 = new Backyard(j, k);
System.out.println( /* missing code */ );
Which of the following can be used as a replacement for /* missing code */ so the code segment works as intended?
a. b1 == b2
b. b1.equals(b2)
c. equals(b1, b2)
d. b1.equals(b2.getLength(), b2.getWidth())
e. b1.length == b2.length && b1.width == b2.width
Answers
Answer:
b. b1.equals(b2)
Explanation:
The question has a missing source file (which can be found online).
The function that compares b1 and b2 is:
public boolean equals(Object other) {
if (other == null) {
return false; }
Backyard b = (Backyard) object;
return (length == b.getLength() && width == b.getWidth());
}
Using the function definition, we have:
equals(Object other)
This implies that, the first object will be compared to the second, using the function name.
i,e,
b1.equals(b2)
Hence (b) is correct
In this exercise we have to use the knowledge in computational language in C++ to describe a code that best suits, so we have:
The code can be found in the attached image.
To make it simpler we can write this code as:
public boolean equals(Object other) {
if (other == null) {
return false; }
Backyard b = (Backyard) object;
return (length == b.getLength() && width == b.getWidth());
}
This program will result in the following missing variable:
b1.equals(b2)
