Explanation:
The following program is written in Java. Since there was not much information provided in the question I created a Vehicle superclass with a couple of subclasses for the different types of vehicles (motorcycle, sedan, truck). Each one having its own unique attributes. The vehicle class also has an attribute for the position of the vehicle in the race.
class Vehicle {
int year, wheels, position;
public Vehicle(int year, int wheels, int position) {
this.year = year;
this.wheels = wheels;
this.position = position;

what is the meaning of antimonographycationalis
Answer:
Although this word was made up in order to be a contender for the longest word in English, it can be broken down into smaller chunks in order to understand it.
Anti- means that you are against something; monopoly means the exclusive control over something; geographic is related to geography; and the remaining part has to do with nationalism.
So this word means something like 'a nationalistic feeling of being against geographic monopoly,' but you can see that it doesn't have much sense.

Given two regular expressions r1 and r2, construct a decision procedure to determine whether the language of r1 is contained in the language r2; that is, the language of r1 is a subset of the language of r2.
Answer:
Test if L(M1-2) is empty.
Construct FA M2-1 from M1 and M2 which recognizes the language L(>M2) - L(>M1).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M2-1) is empty.
Answer yes if and only if both answers were yes.
Explanation:
An algorithm must be guaranteed to halt after a finite number of steps.
Each step of the algorithm must be well specified (deterministic rather than non-deterministic).
Three basic problems:
Given an FA M and an input x, does M accept x?
Is x in L(M)
Given an FA M, is there a string that it accepts?
Is L(M) the empty set?
Given an FA M, is L(M) finite?
Algorithm for determining if M accepts x.
Simply execute M on x.
Output yes if we end up at an accepting state.
This algorithm clearly halts after a finite number of steps, and it is well specified.
This algorithm is also clearly correct.
Testing if L(M) is empty.
Incorrect "Algorithm"
Simulate M on all strings x.
Output yes if and only if all strings are rejected.
The "algorithm" is well specified, and it is also clearly correct.
However, this is not an algorithm because there are an infinite number of strings to simulate M on, and thus it is not guaranteed to halt in a finite amount of time.
COMMENT: Note we use the algorithm for the first problem as a subroutine; you must think in this fashion to solve the problems we will ask.
Correct Algorithm
Simulate M on all strings of length between 0 and n-1 where M has n states.
Output no if and only if all strings are rejected.
Otherwise output yes.
This algorithm clearly halts after a finite number of steps, and it is well specified.
The correctness of the algorithm follows from the fact that if M accepts any strings, it must accept one of length at most n-1.
Suppose this is not true; that is, L(M) is not empty but the shortest string accepted by M has a length of at least n.
Let x be the shortest string accepted by M where |x| > n-1.
Using the Pumping Lemma, we know that there must be a "loop" in x which can be pumped 0 times to create a shorter string in L.
This is a contradiction and the result follows.
COMMENT: There are more efficient algorithms, but we won't get into that.
Testing if L(M) is finite
Incorrect "Algorithm"
Simulate M on all strings x.
Output yes if and only if there are a finite number of yes answers.
This "algorithm" is well specified and correct.
However, this is not an algorithm because there are an infinite number of strings to simulate M on, and thus it is not guaranteed to halt in a finite amount of time.
COMMENT: Note we again use the algorithm for the first problem as a subroutine.
Correct Algorithm
Simulate M on all strings of length between n and 2n-1 where M has n states.
Output yes if and only if no string is accepted.
Otherwise output no.
This algorithm clearly halts after a finite number of steps, and it is well specified.
The correctness of the algorithm follows from the fact that if M accepts an infinite number of strings, it must accept one of length between n and 2n-1.
This builds on the idea that if M accepts an infinite number of strings, there must be a "loop" that can be pumped.
This loop must have length at most n.
When we pump it 0 times, we have a string of length less than n.
When we pump it once, we increase the length of the string by at most n so we cannot exceed 2n-1. The problem is we might not exceed n-1 yet.
The key is we can keep pumping it and at some point, its length must exceed n-1, and in the step it does, it cannot jump past 2n-1 since the size of the loop is at most n.
This proof is not totally correct, but it captures the key idea.
COMMENT: There again are more efficient algorithms, but we won't get into that.
Other problems we can solve using these basic algorithms (and other algorithms we've seen earlier this chapter) as subroutines.
COMMENT: many of these algorithms depend on your understanding of basic set operations such as set complement, set difference, set union, etc.
Given a regular expression r, is Lr finite?
Convert r to an equivalent FA M.
COMMENT: note we use the two algorithms for converting a regular expression to an NFA and then an NFA to an FA.
Test if L(M) is finite.
Output the answer to the above test.
Given two FAs M1 and M2, is L(M1) = L(M2)?
Construct FA M1-2 from M1 and M2 which recognizes the language L(>M1) - L(>M2).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M1-2) is empty.
Construct FA M2-1 from M1 and M2 which recognizes the language L(>M2) - L(>M1).
COMMENT: note we use the algorithm that is instrumental in proving that regular languages are closed with respect to the set difference operator.
Test if L(M2-1) is empty.
Answer yes if and only if both answers were yes.
Unchecked exceptions require you surround the code that might throw such an exception with a try block or you must use a throws statement at the end of the method signature. Failure to do one of these two things will result in a compile error.
a. True
b. False
Answer:
b. False
Explanation:
False, unchecked exceptions do not cause compilation errors and do not require try/catch blocks or throws statements. However, although they are not required it is good programming to include them in order to handle any exceptions that may arise. If you do not include a proper way to handle such an exception the program will still run but may run into an exception during runtime. If this occurs then the entire program will crash because it does not know how to handle the exception since you did not provide instructions for such a scenario.

Write a program that reads integers from the user and stores them in a list. Your
program should continue reading values until the user enters 0. Then it should display
all of the values entered by the user (except for the 0) in order from smallest to largest,
with one value appearing on each line. Use either the sort method or the sorted
function to sort the list.
Answer:
The program in Python is as follows:
numList = []
num = int(input())
while num != 0:
numList.append(num)
num = int(input())
numList.sort()
for num in numList:
print(num)
Explanation:
This initializes the list
numList = []
This gets input from the user
num = int(input())
This loop is repeated until the user enters 0
while num != 0:
This appends the user input to the list
numList.append(num)
This gets another input from the user
num = int(input())
This sorts the list in ascending order
numList.sort()
This iteration prints the list elements, each on a line
for num in numList:
print(num)

A hacker gains access to a web server and reads the credit card numbers stored on that server. Which security principle is violated? Group of answer choices Authenticity Integrity Availability Confidentiality PreviousNext
Answer:
Confidentiality
Explanation:
Cyber security can be defined as a preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cybersecurity, there are certain security standards, frameworks, antivirus utility, and best practices that must be adopted to ensure there's a formidable wall to prevent data corruption by malwares or viruses, protect data and any unauthorized access or usage of the system network.
In this scenario, a hacker gains access to a web server and reads the credit card numbers stored on that server. Thus, the security principle which is violated is confidentiality.
Confidentiality refers to the act of sharing an information that is expected to be kept secret, especially between the parties involved. Thus, a confidential information is a secret information that mustn't be shared with the general public.
This ultimately implies that, confidentiality requires that access to collected data be limited only to authorized staffs or persons.

Develop an algorithm and write a C++ program that finds the number of occurrences of a specified character in the string; make sure you take CString as input and return number of occurrences using call by reference. For example, Write a test program that reads a string and a character and displays the number of occurrences of the character in the string. Here is a sample run of the program:______.
Answer:
The algorithm is as follows:
1. Input sentence
2. Input character
3. Length = len(sentence)
4. count = 0
5. For i = 0 to Length-1
5.1 If sentence[i] == character
5.1.1 count++
6. Print count
7. Stop
The program in C++ is as follows:
#include <iostream>
#include <string.h>
using namespace std;
int main(){
char str[100]; char chr;
cin.getline(str, 100);
cin>>chr;
int count = 0;
for (int i=0;i<strlen(str);i++){
if (str[i] == chr){
count++;} }
cout << count;
return 0;}
Explanation:
I will provide explanation for the c++ program. The explanation can also be extended to the algorithm
This declares the string and the character
char str[100]; char chr;
This gets input for the string variable
cin.getline(str, 100);
This gets input for the character variable
cin>>chr;
This initializes count to 0
int count = 0;
This iterates through the characters of the string
for (int i=0;i<strlen(str);i++){
If the current character equals the search character, count is incremented by 1
if (str[i] == chr){ count++;} }
This prints the count
cout << count;
Several families are planning a shared car trip on scenic drives in New Hampshire's White Mountains. To minimize the possibility of any quarrels, they want to assign individuals to cars so that no two members of a family are in the same car. Explain how to formulate this problem as a network flow problem.
Answer:
Following are the response to the given question:
Explanation:
Build a spring, sink, vertices, and vertices for each car for a household. Every unit in the stream is a human. Attach the source from each vertical of a family with such a capacity line equivalent to the family size; this sets the number of members in each household. Attach every car vertices to the sink with the edge of the car's passenger belt; this assures the correct number of people for every vehicle. Connecting every vertex in your household to any vertex in your vehicle with a capacity 1 border guarantees that one family member joins a single car. The link between both the acceptable allocation of people to vehicles as well as the maximum flow inside the graph seems clear to notice.

Answer:
6 2 and 0
Explanation:
This algorithm doesn't work if the list is not ordered ascending.
In this example it is not, and indeed the item "1" is never found.
first cycle: first=0, last=12 so midpoint=6
second cycle: first=0, last=5 so midpoint=2
last cycle: first=0, last=1 so midpoint=0
then last is assigned -1 so the while statement is no longer true.

Assume the variable sales references a float value. Write a statement that displays the value rounded to two decimal points.Assume the following statement has been executed:
number = 1234567.456
Write a Python statement that displays the value referenced by the number variable formatted as
1,234,567.5
Answer:
The statement is as follows:
print("{0:,.1f}".format(number))
Explanation:
Required
Statement to print 1234567.456 as 1,234,567.5
To do this, we make use of the format keyword, and we set the print format in the process.
To round up number to 1 decimal place, we use the following format:
"{0:,.1f}"
To include comma in the thousand place, we simply include a comma sign before the number of decimal place of the output; i.e. before 1
"{0:,.1f}"
So, the print statement is:
print("{0:,.1f}".format(number))
Write a function addingAllTheWeirdStuff which adds the sum of all the odd numbers in array2 to each element under 10 in array1. Similarly, addingAllTheWeirdStuff should also add the sum of all the even numbers in array2 to those elements over 10 in array1.
Answer:
The function is as follows:
def addingAllTheWeirdStuff(array1,array2):
sumOdd = 0
for i in array2:
if i % 2 == 1:
sumOdd+=i
for i in array1:
if i < 10:
sumOdd+=i
print("Sum:",sumOdd)
sumEven = 0
for i in array1:
if i % 2 == 0:
sumEven+=i
for i in array2:
if i > 10:
sumEven+=i
print("Sum:",sumEven)
Explanation:
This declares the function
def addingAllTheWeirdStuff(array1,array2):
This initializes the sum of odd numbers in array 2 to 0
sumOdd = 0
This iterates through array 2
for i in array2:
This adds up all odd numbers in it
if i % 2 == 1:
sumOdd+=i
This iterates through array 1
for i in array1:
This adds up all elements less than 10 to sumOdd
if i < 10:
sumOdd+=i
This prints the calculated sum
print("Sum:",sumOdd)
This initializes the sum of even numbers in array 1 to 0
sumEven = 0
This iterates through array 1
for i in array1:
This adds up all even numbers in it
if i % 2 == 0:
sumEven+=i
This iterates through array 2
for i in array2:
This adds up all elements greater than 10 to sumEven
if i > 10:
sumEven+=i
This prints the calculated sum
print("Sum:",sumEven)

Write a function called rotateRight that takes a String as its first argument and a positive int as its second argument and rotates the String right by the given number of characters. Any characters that get moved off the right side of the string should wrap around to the left.
Answer:
The function in Python is as follows:
def rotateRight(strng, d):
lent = len(strng)
retString = strng[lent - d : ] + strng[0 : lent - d]
return retString
Explanation:
This defines the function
def rotateRight(strng, d):
This calculates the length of the string
lent = len(strng)
This calculates the return string
retString = strng[lent - d : ] + strng[0 : lent - d]
This returns the return string
return retString
Addition:
The return string is calculated as thus:
This string is split from the index passed to the function to the last element of the string, i.e. from dth to last.
The split string is then concatenated to the beginning of the remaining string
