Question Statement: Explain the steps needed to the display all the items in a linked list
Answer:
A list of linked data structures is a sequence of linked data structures.
The Linked List is an array of links containing items. Each link contains a link to a different link. The second most frequently used array is the Linked List.
Explanation:
Create a node class with 2 attributes: the data and the following. Next is the next node pointer.
Create an additional class with two attributes: head and tail.
AddNode() adds to the list a new node:
Make a new node.
He first examines if the head is equal to zero, meaning that the list is empty.
The head and the tail point to the newly added node when this list is vacant.
If the list isn't empty, the new node will be added at the end of the list to point to the new node of tail. This new node is the new end of the list.
Show() will show the nodes in the list:
Set a node current that first points to the list header.
Cross the list until the current null points.
Show each node by referring to the current in each iteration to the next node.

Explanation:
Bitmap is the technique for mapping from some domain bits. This is particularly referred to as pix-map which is actually map of pixels and this contains more than two colors. it used more than one bit per pixel. Pixels lesser than 8 will represent gray scale.
Write a program that reads in 10 numbers and displays the number of distinct numbers and the distinct numbers in their input order and separated by exactly one space (i.e., if a number appears multiple times, it is displayed only once). After the input, the array contains the distinct numbers. Here is a sample run of the program.
Answer:
Explanation:
The following code is written in Python. It creates a for loop that iterates 10 times, asking the user for a number every time. It then checks if the number is inside the numArray. If it is not, then it adds it to the array, if it is then it skips to the next iteration. Finally, it prints the number of distinct numbers and the list of numbers.
numArray = []
for x in range(10):
num = input("Enter a number")
if int(num) not in numArray:
numArray.append(int(num))
print("Number of Distince: " + str(len(numArray)))
for num in numArray:
print(str(num), end = " ")

how data transform into information?
I have been working on this python program for a hour now, and I am trying to figure out what I an doing wrong in the loop. I have attached the code and screenshot of my work. I need help to figure out how to loop the rest of the years for a calculation. The calculation has looped the same result for all years.
This is the assignment:
In 2017, the tuition for a full time student is $6,450 per semester. The tuition will be going up for the next 7 years at a rate of 3.5% per year. Write your python program using a loop that displays the projected semester tuition for the next 7 years. You should display the actual year (2018, 2019, through 2024) and the tuition amount per semester for that year.
Here is my code:
# declare global constant variables
startingTuition = 6450.00;
starting_tuitionYear = 2018;
ending_tuitionYear = 2025;
increment = 1;
rate = .035;
tuition = 0;
tuitionRate = 0;
#loop for the next 7 years
for year in range(starting_tuitionYear, ending_tuitionYear, increment):
# calculate rate per year
tuitionRate = (rate)*startingTuition;
# add rate per year to the tuition fee
tuition = startingTuition + tuitionRate;
print('Tuition for the year of ' + str(year)+ ' is ' + str(tuition));
Answer:
The correct loop is as follows:
for year in range(starting_tuitionYear, ending_tuitionYear, increment):
tuition = startingTuition + rate * startingTuition
startingTuition = tuition
print('Tuition for the year of ' + str(year)+ ' is ' + str(tuition));
Explanation:
Required
The correction to the attached program
Some variables are not needed; so, I've removed the redundant variables.
The main error in the program is in the loop;
After the tuition for each year has been calculated, the startTuition of the next year must be set to the current tuition

Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or any string with a non-integer character, the output is: no
Answer:
Following are the program to the given question:
def check_digit(number): #defining a method check_digit that takes number variable in parameter
if(numumber.isdigit()): #use if to check value is digit
return "yes"; #use return to return string value "yes"
else: #else block
return "no";#use return to return string value "no"
string=input("Enter the numbers 0-9: ") #defining a variable string that input value from the user
print(check_digit(string)) #use print that call the method and print its return value
Output:
Please find the attached file.
Explanation:
In this code a method "check_digit()", which accepts an argument "number" in its parameter inside the function.
A conditional statement is used if it checks the number used "isdigit()" method that checks value is a digit and return value "yes" and in the else block it will return value "no".
Outside the method, a variable "string" is declared that input the value from the user-end and call the check_digit and print its value.
Security monitoring has detected the presence of a remote access tool classified as commodity malware on an employee workstation. Does this allow you to discount the possibility that an APT is involved in the attack
Answer:
No it doesn't
Explanation:
Targeted malware can be linked to such high resource threats as APT. Little or nothing can be done to stop such advanced persistent threats. It is necessary to carry out an evaluation on other indicators so that you can know the threat that is involved. And also to know if the malware is isolated or greater than that.

Create a static method that: - is called appendPosSum - returns an ArrayList - takes one parameter: an ArrayList of Integers This method should: - Create a new ArrayList of Integers - Add only the positive Integers to the new ArrayList - Sum the positive Integers in the new ArrayList and add the Sum as the last element For example, if the incoming ArrayList contains the Integers (4,-6,3,-8,0,4,3), the ArrayList that gets returned should be (4,3,4,3,14), with 14 being the sum of (4,3,4,3). The original ArrayList should remain unchanged.
Answer:
The method in Java is as follows:
public static ArrayList<Integer> appendPosSum(ArrayList<Integer> nums) {
int sum = 0;
ArrayList<Integer> newArr = new ArrayList<>();
for(int num : nums) {
if(num>0){
sum+=num;
newArr.add(num); } }
newArr.add(sum);
return newArr;
}
Explanation:
This defines the method; it receives an integer arraylist as its parameter; nums
public static ArrayList<Integer> appendPosSum(ArrayList<Integer> nums) {
This initializes sum to 0
int sum = 0;
This declares a new integer arraylist; newArr
ArrayList<Integer> newArr = new ArrayList<>();
This iterates through nums
for(int num : nums) {
If current element is greater than 0
if(num>0){
This sum is taken
sum+=num;
And the element is added to newArr
newArr.add(num); } }
At the end of the iteration; this adds the calculated sum to newArr
newArr.add(sum);
This returns newArr
return newArr;
}

write a program in C# that reads a set of integers and then finds and prints the sum of the even and odd integers?
Answer:
The program in C# is as follows:
using System;
class Prog {
static void Main() {
int n;
Console.WriteLine("Number of integers: ");
n = Convert.ToInt32(Console.ReadLine());
int evensum = 0, oddsum = 0; int inpt;
for(int i = 0;i<n;i++){
inpt = Convert.ToInt32(Console.ReadLine());
if(inpt%2==0){ evensum+=inpt; }
else{ oddsum+=inpt; }
}
Console.WriteLine(evensum);
Console.WriteLine(oddsum);
}
}
Explanation:
This declares n, the number of integer inputs
int n;
This prompts for n
Console.WriteLine("Number of integers: ");
This gets input for n
n = Convert.ToInt32(Console.ReadLine());
This declares and initializes the even and odd sum.
int evensum = 0, oddsum = 0; int inpt;
This iterates through n
for(int i = 0;i<n;i++){
This gets each input
inpt = Convert.ToInt32(Console.ReadLine());
Check for even numbers and add,if even
if(inpt%2==0){ evensum+=inpt; }
Otherwise, add input as odd

What term refers the built-in redundancy of an application's components and the ability of the application to remain operational even if some of its components fail
Answer:
Fault tolerance.
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer on how to perform a specific task and solve a particular problem.
Simply stated, it's a computer program or application that comprises of sets of code for performing specific tasks on the system.
Fault tolerance is an ability of the component of a software application or network to recover after any type of failure. Thus, it is the redundancy of an application's components built-in by default and the ability of this software application to remain functional or operational even if some of its components fail or it encounter some code blocks.
Basically, fault tolerance makes it possible for a software application or program to continue with its normal operations or functions regardless of the presence of hardware or system component failure.
Hence, it is an important requirement for any software application that should be incorporated by software developers during the coding stage of the software development life cycle (SDLC).
