Explanation:
"Two threads try to acquire the same resource at the same time and both are blocked. Then, they continually change their states in the same way and are continuously blocked. This condition is called" LIVELOCK.
The term ''livelock" in is a very good and a very important in aspect that is related to computing. LIVELOCK simply means a lock in which the process in denied multiple times. A perfect example is;
When a person A and a person meet on a very narrow path. Both person A and Person B will want to shift to a position which will allow each of them to pass(This are the processes Person A and B wants to take), so if the two now move to the same exact position instead of moving in an opposite direction then, we will say that we have a LIVELOCK.

The program is an illustration of loops and conditional statements.
Loops are used to perform repetitive operations, while conditional statements are statements whose execution depends on the truth value.
The program in Java, where comments are used to explain each line is as follows:
import java.util.*;
class Main {
public static void main (String[] args) {
//This creates a scanner object
Scanner input = new Scanner(System.in);
//This gets input for n
int n= input.nextInt();
//This declares array a
int []a = new int [n];
//The following loop gets input for array a
for(int i=0;i<n;i++){
a[i]=sc.nextInt();
}
//This declares array b
int []b = new int [n];
//The following loop mutates array a to b
for(int i=0;i<n;i++){
b[i]=0;
if(((i-1)>=0)&&((i-1)<n)){
b[i]+=a[i-1];
}
if(((i)>=0)&&((i)<n)){
b[i]+=a[i];

}
}
//The following loop prints the mutated array b
for(int i=0;i<n;i++){
System.out.print(b[i]+" ");
}
}
}
At the end of the program, the elements of the mutated array b, are printed on the same line (separated by space).

The difrent between valid deductive argument and strong inductive argument? At least 2 example
Answer:
If the arguer believes that the truth of the premises definitely establishes the truth of the conclusion, then the argument is deductive. If the arguer believes that the truth of the premises provides only good reasons to believe the conclusion is probably true, then the argument is inductive.
ALSO
Deductive arguments have unassailable conclusions assuming all the premises are true, but inductive arguments simply have some measure of probability that the argument is true—based on the strength of the argument and the evidence to support it.

Canadian Tire is one of Canada’s largest companies. They operate four large distribution centers service over 470 tire retail outlets. They recently installed a Yard Management System (YMS), which they have integrated with their Warehouse Management Systems (WMS) and Transport Management System (TMS) systems. Their expectation was improved performance in over-the-road transportation equipment utilization, driver productivity, and warehouse dock/door utilization. As a relatively new logistics employee, you have been asked to develop an evaluation system to measure operational productivity improvement. While management does not want a financial impact evaluation, they are interested in developing benchmarks to measure initial and sustainable productivity improvement. You have the job-how would you proceed?
Answer: Provided in the explanation section
Explanation:
A YMS acts an interface between a WMS and TMS.The evaluation system with the key performance indicators are mentioned in the table below.
NOTE: The analysis follows in this order given below
MetricDescriptionCommentsMetric 1
Trailer utilization
Description :This captures the status of the trailer whether it is in the yard or is in transit
Comments : Helps in measuring the trailer productivity on a daily ,weekly or monthly basis
Metric 2
Driver utilization
Description : This captures the status of the driver whether the driver is in the yard or is in transit
Comments : Helps in measuring the driver productivity on a periodic basis
Metric 3
Trailer sequence
Description : This captures the order of movement of trailers in the yard on a given day, week or month
Comments : Helps in measuring the order fulfilment efficiency i.e. whether the priority orders have been serviced first or not
Metric 4
Total time in yard
Description : This captures the time spent by the trailer in the yard from the time it enters and leaves the yard
Comments : This helps in measuring the time taken to fulfill a particular request
⇒ Capturing these metrics need inputs from both WMS and TMS, and also the trailers need to have RFID tags attached to them.Then compare these performance metrics with the ones prior to the deployment of YMS to identify the percent gains in the overall operational productivity.

Explanation:
The main() function call the function getMileage() function after that the control moves to the getMileage() definition of function. In this firstly declared the "mileage" variable after that it taking the input and module is finished we see that the "mileage" variable is local variable i,e it is declared inside the " Module getMileage() " and we prints in the main module that are not possible to correct these we used two technique.
Technique 1: Declared the mileage variable as the global variable that is accessible anywhere in the program.
Technique 2: We print the value of "mileage" inside the Module getMileage() in the program .

Given a set, weights, and an integer desired_weight, remove the element of the set that is closest to desired_weight (the closest element can be less than, equal to OR GREATER THAN desired_weight), and associate it with the variable actual_weight. For example, if weights is (12, 19, 6, 14, 22, 7) and desired_weight is 18, then the resulting set would be (12, 6, 14, 22, 7) and actual_weight would be 19. If there is a tie, the element LESS THANdesired_weight is to be chosen. Thus if the set is (2, 4, 6, 8, 10) and desired_weight is 7, the value chosen would be 6, not 8. Assume there is at least one value in the set.
Answer:
In the question stated a we declared a set named as weights also an integer variable was the desired_weight
In python A set is regarded as {12, 19, 6, 14, 22, 7}
Explanation:
Solution
The python program code is executed below:
# Declare a tuple
weights = (12, 19, 6, 14, 22, 7)
# Declare an integer variable to store desired weight.
desired_weight = 18
# Declare an integer variable to store actual_weight weight
actual_weight = weights[0]
# Create a for-loop to read each value in the tuple.
for each_weight in weights:
# Create an if-statement to find the that is
# closest weight but not greater than desired weight.
if(each_weight > actual_weight and each_weight < desired_weight):
actual_weight = each_weight
weights=list(weights)
# Delete the actual weight
weights.remove(actual_weight)
weights=tuple(weights)
# Display the actual weight
print("Actual Weight:",actual_weight)
# Display the resulted tuple.
print("Resulted set:",weights)
This program here is to declare a set which is as follows:
# Declare a set
weights = {12, 19, 6, 14, 22, 7}
# Declare an integer variable to store desired weight.
desired_weight = 18
# Declare an integer variable to store actual weight
# Assign first index element using list.
actual_weight = list(weights)[0]
# Create a for-loop to read each value in the tuple.
for each_weight in weights:
# Create an if-statement to find the that is
# closest weight but not greater than desired weight.
if(each_weight > actual_weight and each_weight < desired_weight):
actual_weight = each_weight
# Delete the actual weight using discard() method.
weights.discard(actual_weight)
# Display the actual weight
print("Actual Weight:",actual_weight)
# Display the resulted tuple.
print("Resulted set:",weights)
(TCO C) When a remote user attempts to dial in to the network, the network access server (NAS) queries the TACACS+ server. If the message sent to the server is REJECT, this means _____.
Answer:
The correct answer to the following question will be "The user is prompted to retry".
Explanation:
NAS seems to be a category of server system a broader open internet as well as web through in-house and perhaps remotely associated user groups.
It handles as well as provides linked consumers the opportunity to provide a collection of network-enabled applications collectively, thereby integrated into a single base station but rather portal to infrastructure.Unless the text or response sent to the server seems to be REJECT, this implies that the authentication process continued to fail and therefore should be retried.A security professional wants to test a piece of malware that was isolated on a user's computer to document its effect on a system. Which of the following is the FIRST step the security professional should take?
A. Create a sandbox on the machine.
B. Open the file and run it.
C. Create a secure baseline of the system state.
D. Hardon the machine
Answer:
The correct answer is option (A) Create a sandbox on the machine
Explanation:
Solution
From the example given, the first step the security professional should take is to create a sandbox on the machine.
Sandbox: It refers to as a remote testing environment that allows users to run programs or implement files without distorting the application, system or platform on which they run.
In areas of computer security a sandbox is a security technique used for separating running programs, normally in an effort to reduce system failures or software vulnerabilities from moving further.

Description
There is a cricket that lives by our timeshare in Myrtle Beach, South Carolina. Most every night I hear it patiently chirping away. Some nights it chirps faster than others, and it seems like the warmer it is, the faster it chirps. There are many crickets, and each of them seems to behave the same. On several different nights, armed with a stopwatch and a thermometer, I recorded the frequency of the chirps and compared it to that night's air temperature.
Experimental Results
The chirping follows a simple linear formula: take the number of chirps, add 40 and divide that sum by four to get the temperature in degrees Fahrenheit.
Assignment
Create a simulation to model the crickets chirping at various randomly generated frequencies, create an Environmentclass that knows and can return the current temperature. Create a Cricket class that chirps, or for simplicity, returns how many chirps per minute the cricket would make at that temperature. Repeat the simulation for at least three trials.
Extension: There is a cricket variety in some parts of South Carolina that is a little slower than most normal Carolina crickets. Add a ClemsonCricket class that extends Cricket but chirps slower by 20%.
Bonus: Implement polymorphism in the driver class.
Rubrics
Cricket class should include the following items:
A variable that stores the frequency of chirps.
A default constructor that initializes the frequency to a random value
An overloaded constructor that initializes the frequency to a value of your choice that gets passed on as a parameter.
A method for changing the frequency to a random value.
A getter method that returns the frequency.
clemsonCricket class should include the following items:
A default constructor that initializes the frequency to a random value that is 20% lower than what the parent class constructor would initialize it to.
A overloaded constructor that calls to the parent constructor.
A polymorphic method that changes the frequency value to a value that is 20% lower than what the parent method would change it to.
Environment class should include the following items:
A variable that stores the temperature.
A default constructor that initializes the temperature to a value of your choosing.
An overloaded constructor that initializes the temperature based on the formula in the assignment.
A method that takes in a frequency as a parameter and calculates the temperature based on the formula in the assignment.
testCrickets program should do the following items:
Creates an Environment object in the test program or in the Cricket or clemsonCricket classes and displays temperature Creates a cricket object and displays temperature before and after changing frequency
Creates a Clemson cricket object and displays temperature before and after changing frequency
Creates a polymorphic Clemson cricket object and displays temperature before and after changing frequency.

cheers i hope this helped !!
Given parameters b and h which stand for the base and the height of an isosceles triangle (i.e., a triangle that has two equal sides), write a C program that calculates: The area of the triangle; The perimeter of the triangle; And The volume of the cone formed by spinning the triangle around the line h The program must prompt the user to enter b and h (both of type double) The program must define and use the following three functions: Calc Area (base, height) //calculates and returns the area of the triangle Calc Perimeter (base, height) //calculates and returns the perimeter Calc Volume(base, height) //calculates and returns the volume
Answer:
The area of the triangle is calculated as thus:
[tex]Area = 0.5 * b * h[/tex]
To calculate the perimeter of the triangle, the measurement of the slant height has to be derived;
Let s represent the slant height;
Dividing the triangle into 2 gives a right angled triangle;
The slant height, s is calculated using Pythagoras theorem as thus
[tex]s = \sqrt{b^2 + h^2}[/tex]
The perimeter of the triangle is then calculated as thus;
[tex]Perimeter = s + s + b[/tex]
[tex]Perimeter = \sqrt{b^2 + h^2} + \sqrt{b^2 + h^2} +b[/tex]
[tex]Perimeter = 2\sqrt{b^2 + h^2} + b[/tex]
For the volume of the cone,
when the triangle is spin, the base of the triangle forms the diameter of the cone;
[tex]Volume = \frac{1}{3} \pi * r^2 * h[/tex]
Where [tex]r = \frac{1}{2} * diameter[/tex]
So, [tex]r = \frac{1}{2}b[/tex]
So, [tex]Volume = \frac{1}{3} \pi * (\frac{b}{2})^2 * h[/tex]
Base on the above illustrations, the program is as follows;
#include<iostream>
#include<cmath>
using namespace std;
void CalcArea(double b, double h)
{
//Calculate Area
double Area = 0.5 * b * h;
//Print Area
cout<<"Area = "<<Area<<endl;
}
void CalcPerimeter(double b, double h)
{
//Calculate Perimeter
double Perimeter = 2 * sqrt(pow(h,2)+pow((0.5 * b),2)) + b;
//Print Perimeter
cout<<"Perimeter = "<<Perimeter<<endl;
}
void CalcVolume(double b, double h)
{
//Calculate Volume
double Volume = (1.0/3.0) * (22.0/7.0) * pow((0.5 * b),2) * h;
//Print Volume
cout<<"Volume = "<<Volume<<endl;
}
int main()
{
double b, h;
//Prompt User for input
cout<<"Base: ";
cin>>b;
cout<<"Height: ";
cin>>h;
//Call CalcVolume function
CalcVolume(b,h);
//Call CalcArea function
CalcArea(b,h);
//Call CalcPerimeter function
CalcPerimeter(b,h);
return 0;
}
Write a program that prompts the user to enter three cities and displays them in ascending order. Here is a sample run: Enter the first city: Chicago Enter the second city: Los Angeles Enter the third city: Atlanta The three cities in alphabetical order are Atlanta Chicago Los Angeles
Answer:
import java.util.Scanner;
public class SortStrings3 {
public static void main(String args[]){
Scanner scanner = new Scanner(System.in);
String str1, str2, str3;
System.out.print("Enter the first city: ");
str1 = scanner.nextLine();
System.out.print("Enter the second city: ");
str2 = scanner.nextLine();
System.out.print("Enter the third city: ");
str3 = scanner.nextLine();
System.out.print("The three cities in alphabetical order are ");
if(str1.compareTo(str2) < 0 && str1.compareTo(str3) < 0){
System.out.print(str1+" ");
if(str2.compareTo(str3) < 0){
System.out.print(str2+" ");
System.out.println(str3);
}
else {
System.out.print(str3+" ");
System.out.println(str2);
}
}
else if(str2.compareTo(str1) < 0 && str2.compareTo(str3) < 0){
System.out.print(str2+" ");
if(str1.compareTo(str3) < 0){
System.out.print(str1+" ");
System.out.println(str3);
}
else {
System.out.print(str3+" ");
System.out.println(str1);
}
}
else{
System.out.print(str3+" ");
if(str1.compareTo(str2) < 0){
System.out.print(str1+" ");
System.out.println(str2);
}
else {
System.out.print(str2+" ");
System.out.println(str1);
}
}
}
}
EXPLANATION:
Okay, we are given that a program should be written which will make user to enter three cities namely Atlanta, Chicago and Los Angeles (which should be done in ascending alphabetical order).
So, we will be writting the code or program with a programming language known as JAVA(JUST ANOTHER VIRTUAL ACCELERATOR).
We will make use of java to write this program because Java can be used in Loading code, verifying codes and executing codes on a single or multiple servers.
The code or program can be seen in the attached file/document. Kindly check it.
First, define an integer variable and assign it any value of your choice. Then you'll need to perform the following operations with it:
1. Add 9
2. Multiply by 2
3. Subtract 4
4. Divide by 2
5. Subtract by the variable's original value
6. Finally, display what the end result is.
7. Once your math / code is complete, double check your work by seeing what happens with the end result when you use different starting values. You should notice something "interesting".
In this scenario, two friends are eating dinner at a restaurant. The bill comes in the amount of 47.28 dollars. The friends decide to split the bill evenly between them, after adding 15% tip for the service. Calculate the tip, the total amount to pay, and each friend's share, then output a message saying "Each person needs to pay: " followed by the resulting number.
Answer:
The java program for the given scenario is as follows.
import java.util.*;
import java.lang.*;
public class Main
{
//variables for bill and tip declared and initialized
static double bill=47.28, tip=0.15;
//variables for total bill and share declared
static double total, share1;
public static void main(String[] args) {
double total_tip= (bill*tip);
//total bill computed
total = bill + total_tip;
//share of each friend computed
share1 = total/2;
System.out.printf("Each person needs to pay: $%.2f", share1);
}
}
Explanation:
1. The variables to hold the bill and tip percent are declared as double and initialized with the given values.
static double bill=47.28, tip=0.15;
2. The variables to hold the values of total bill amount and total tip are declared as double.
3. All the variables are declared outside main() and at class level, hence declared as static.
4. Inside main(), the values of total tip, total bill and share of each person are computed as shown.
double total_tip= (bill*tip);
total = bill + total_tip;
share1 = total/2;
5. The share of each person is displayed to the user. The value is displayed with only two decimal places which is assured by %.2f format modifier. The number of decimal places required can be changed by changing the number, i.e. 2. This format is used with printf() and not with println() method.
System.out.printf("Each person needs to pay: $%.2f", share1);
6. The program is not designed to take any user input.
7. The program can be tested for any value of bill and tip percent.
8. The whole code is put inside a class since java is a purely object-oriented language.
9. Only variables can be declared outside method, the logic is put inside a method in a purely object-oriented language.
10. As shown, the logic is put inside the main() method and only variables are declared outside the method.
11. Due to simplicity, the program consists of only one class.
12. The output is attached.
Answer:
bill = 47.28
tip = bill *.15
total = bill + tip
share = total
print( "Each person needs to pay: "+str(share) )
