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.

Some popular examples of today's interpreters are:

Explanation:

An interpreter executes the commands directly in an object code or a machine code, written in a program or a scripting language.

The Interpreter can be referred to as system software that can read and execute the programme instead of interpreting programmes. This interpretation includes high-level source code, pre-compiled programmes and scripts.

It is important to note that the interpreter translates programme by programme line, meaning that one statement is translated on one go. This feature makes it easy for programmers to check any line on debugging but slows the whole programme running time.

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.

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.

Answer:

4. A. Pliers

5. C. Electrical Tape

6.  B. Cutter

Explanation:

Answer:

Step 1 : Start

Step 2 : Set target= 0

Step 3 : Use a While loop

Step 4 : input donation

Step 5 : Sum - - > target += donation

Step 6 :, check loop condition

Step 7 : End

Explanation:

Algorithm is a sequence of written instructions or steps which we want the computer to in other to solve a particular problem :

Counter is set at 0

Total amount is initially set to := 0

Using a while loop ;

While target amout is less than 200 ; user inputs the amout to donate and it is added to target amount. This loop continues until target amount is greater than 200. Then the loop terminates.

Answer:

A lower bound on the optimal integer value.

Explanation:

The question is poorly typed.  The original question requires the optimal solution of the objective function of a minimization problem

I will answer this question base on the above illustration.

When an objective function is to be minimized, it means that the objective function will take the feasible solution with the least value.

The least value are often referred to as the lower bound.

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.

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)

The DoubleDecimalTest class is as follows:

using System;

class DoubleDecimalTest {

 static void Main() {

     double doubleNum = 173737388856632566321737373676D;  

    decimal decimalNum = 173737388856632566321737373676M;

   Console.WriteLine(doubleNum);

   Console.WriteLine(decimalNum);  } }

Explanation:

Required

Program to test double and decimal variables in C#

This declares and initializes double variable doubleNum

     double doubleNum = 173737388856632566321737373676D;

This declares and initializes double variable decimalNum (using the same value as doubleNum)

     decimal decimalNum = 173737388856632566321737373676M;

This prints doubleNum

   Console.WriteLine(doubleNum);

This prints decimalNum

   Console.WriteLine(decimalNum);

Unless the decimal variable is commented out or the value is reduced to a reasonable range, the program will not compile without error.

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.

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)

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
