The DeckOfCards class manages a deck of 52 Card objects. It provides methods to shuffle, deal a card, report the number of cards left, and display the deck.

To implement the DeckOfCards class, we can utilize the Card class you created in Assignment 4 and add methods to manage a deck of cards. The UML Class diagram for DeckOfCards might look like:

+-----------------------------------+

|          DeckOfCards          |

+-----------------------------------+

| - cards: List<Card>           |

+-----------------------------------+

| + DeckOfCards()              |

| + shuffle()                         |

| + dealCard(): Card           |

| + cardsLeft(): int               |

| + toString(): String            |

+-----------------------------------+

The DeckOfCards class contains a List of Card objects, representing the deck. The constructor initializes the deck, and the shuffle method randomizes the order of cards. The dealCard method returns the top card and reduces the count of remaining cards. The cardsLeft method returns the count of remaining cards, and toString provides a string representation of the deck.

Here's a simplified implementation in Java:

import java.util.ArrayList;

import java.util.Collections;

import java.util.List;

public class DeckOfCards {

   private List<Card> cards;

   public DeckOfCards() {

       cards = new ArrayList<>();

       for (int suit = 1; suit <= 4; suit++) {

           for (int faceValue = 1; faceValue <= 13; faceValue++) {

               cards.add(new Card(suit, faceValue));

           }

       }

   }

   public void shuffle() {

       Collections.shuffle(cards);

   }

   public Card dealCard() {

       if (cards.isEmpty()) {

           return null; // Deck is empty

       }

       return cards.remove(0);

   }

   public int cardsLeft() {

       return cards.size();

   }

   public String toString() {

       StringBuilder deckString = new StringBuilder();

       for (Card card : cards) {

           deckString.append(card.toString()).append("\n");

       }

       return deckString.toString();

   }

}

For the driver class, you can create an instance of DeckOfCards, print the initial deck, shuffle it, and then deal and print each card from the shuffled deck.

The question probable maybe:

In Assignment 4, you created a Card class that represents a standard playing card. Use this to design and implement a class called DeckOfCards that stores 52 objects of the Card class. Include methods to shuffle the deck, deal a card, and report the number of cards left in the deck, and a toString to show the contents of the deck. The shuffle methods should assume a full deck. Document your design with a UML Class diagram. Create a separate driver class that first outputs the populated deck to prove it is complete, shuffles the deck, and then deals each card from a shuffled deck, displaying each card as it is dealt.

Hint: The constructor for DeckOfCards should have nested for loops for the face values (1 to 13) within the suit values (1 to 4). The shuffle method does not have to simulate how a deck is physically shuffled; you can achieve the same effect by repeatedly swapping pairs of cards chosen at random.

       // Recall function 9 time with (n-1) digits

       for (int i = start; i <= 9; i++)

       {

           // append current digit to number

           String str = out + Integer.toString(i);

           // recurse for next digit

           findStrictlyIncreasingNum(i + 1, str, n - 1);

       }

   }

   // Driver code for above function

   public static void main(String args[])

   {   //User Input

       Scanner sc = new Scanner( System.in);

}

//End of Code

Answer:

=(I8+F5)/16

Explanation:

In cell I9, we type the following

=(I8+F5)/16

I8 is the boxed set net weight

F5 is the packing weight

The question asked us to add and divide by 16

We use the addition operator '+' instead of built-in "SUM" function as required by the question.

So, we add I8 and F5 and then divide by 16 in cell I9.

Answer:

number = int(input("Enter a number: "))

product = 1

while number > 0:

   digit = number % 10

   number -= digit

   number /= 10

   product *= digit

print(int(product))

Explanation:

*The code is in Python

Ask the user for an integer

Initialize the product variable that will hold the multiplication of the digits

Initialize a while loop that iterates until number is greater than 0

To find the digit of a number, use number modulo 10. Then subtract the result from the number and divide the new number by 10.

Multiply each digit and hold the value in the product

When the loop is done, print the product

Where:

From the question, the cells to compare are:

So, the IF function that compares both cells is:

[tex]\mathbf{=IF(A4 > A3, "yes", "no")}[/tex]

The above formula checks if A4 is greater than A3.

The question requires that the cells are referenced using absolute cell referencing.

This means that, we make use of the dollar sign ($), when writing the cells.

Final answer:

To encrypt the plaintext message, Bob uses Alice's public key and a random element. The ciphertext is obtained by multiplying the plaintext message with the public key. To decrypt the ciphertext, Alice uses her private key by multiplying the ciphertext with the private key polynomial and reducing modulo p.

Explanation:

To encrypt the plaintext message, Bob needs to use Alice's public key along with a random element. The ciphertext is obtained by multiplying the plaintext message with the public key. In this case, the plaintext message m(x)= 1+ X − X2 − X3 − X6 and the random element r(x) = −1 + X2 − X5 + X6. By multiplying these polynomials, Bob obtains the ciphertext c(x)= -1 - X - X^2 + 4X^3 + 8X^4 - 5X^5 - 30X^6 + 5X^7 - 6X^9 - 3X^10 + 8X^11 + 13X^12 + 2X^13 - 6X^14 + 26X^15 - 16X^16.

To decrypt the ciphertext, Alice uses her private key. She multiplies the ciphertext with her private key polynomial and reduces modulo p, resulting in the decrypted message. The private key polynomial for Alice is f(x) = −1 + X − X2 + X4 + X6. By multiplying the ciphertext c(x) with the private key polynomial f(x) modulo 3, the decrypted message is obtained: d(x)= 1+ X − X2 − X3 − X6.

Replace/* Your code goes here */ with

for(int count = 0; count<4; count++)

{

if(keysList[count] > 40)

{

cout<<itemsList[count]<<" ";

}

}

Explanation;

The solution provides used an iteration to loop from the first toll the last.

The index of an array starts at 0

The index of the last element is calculated as total element - 1

Since the count of the array is 4, the last index is 4 - 1 = 3.

In the solution provides, a count integer variable is declared to iterate through the keysList array

Each element of keysList array is tested to know if it's greater than 40.

If yes the corresponding element in itemsList is printed followed by a space

Else

Nothing is done

The codes segment goes thus

for(int count = 0; count<4; count++)

{

if(keysList[count] > 40)

{

cout<<itemsList[count]<<" ";

}

}

The program which displays the number of positive and negative values inputted. The program written in python 3 goes thus :

#initialize a variable to hold the number of negative values

sum = 0

#initialize a variable to hold the sum of all values

while True :

#A while loop is initiated

val = int(input("Enter integer values except 0 : "))

#prompts user for inputs

if val == 0 :

#checks if inputted value is 0

 break

#if True end the program

else :

#otherwise

 sum +=val

#add the value to the sum variable

 if val > 0 :

#checks if value is greater than 0

  pos_val += 1

#if true increase positive value counts by 1

 else :

  neg_val += 1

#if otherwise, increase negative value counts by 1

freq = float(pos_val + neg_val )

#calculates total number of values

print('The number of positive values is = ', pos_val)

#display number of positive values

print('The number of negative values is = ', neg_val)

Exposure of kids to unwanted pages, poor power system and refusal to backup works are some of the risk analysts

Explanation:

RISK ANALYSIS

1. Kids access to unwanted pages and sites if online are a big risk to private information and exposure to threat from hackers and information scammers

2. Poor power system results in an abrupt shutdown of system which is not encouraged. This is commonly responsible for system breakdown and other malfunctioning of the system

3. Lack of backup structure when not put in place are a very good avenue to home network risk which could have a very harmful effect to the home network activities.

DISASTER RECOVERY PLANS

1. Establish a system recovery and restore plans that could help you roll back actions when there is a system error that prevents the network from booting or starting up.

2. Establish a system restriction plan on your home network when kids and children are involved in it usage else vital information and configurations could be hampered. Focus in this context should also be geared towards website control system and constant system monitoring structure.

3. Power backup plans must include setting up a steady power source which should serve as alternatives to inconsistent power outage, irregular power supply and possible related issues. Such power structure should be able to mitigate for any network activities that requires a long time to backup

4. Other home network activities that requires consistent and constant backup should be done through external storage devices and through on line drives in order to ensure that document are not lost when emergency breakdown occurs.

MIPS designs are used in SGI's computer product line; in many embedded systems; on Windows CE devices; Cisco routers; and video consoles such as the Nintendo 64 or the Sony PlayStation, PlayStation 2 and PlayStation Portable. Most recently, NASA used one of them on the New Horizons probe1.

Explanation:

The earliest MIPS architectures were 32-bit fsfs (generally 32-bit wide data paths and registers), although later versions were implemented in 64-bit. There are five backward compatible revisions of the MIPS instruction set, called MIPS I, MIPS II, MIPS III, MIPS IV, and MIPS 32/64. In the last of these, MIPS 32/64 Release 2, a record control set is defined to major. Also several "extensions" are available, such as the MIPS-3D, consisting of a simple set of floating point SIMD instructions dedicated to common 3D tasks, the MDMX (MaDMaX) made up of a more extensive set of integer SIMD instructions that use 64-bit floating-point registers, MIPS16 which adds compression to the instruction flow to make programs take up less space (presumably in response to the Thumb compression technology of the ARM architecture) or the recent MIPS MT that adds multithreading functionalities similar to the HyperThreading technology of Intel Pentium 4 processors

Explanation:

In our grammar for arithmetic expression, the start symbol is <expression>, so our initial string is:

<expression >

Using rule 5 we can choose to replace the nonterminal, producing the string:

<expression >*<expression >

We now have two nonterminals, to replace, we can apply rule three to the first nonterminal, producing the string:

<expression >+<expression>*<expression>

We can apply rule two to the remaining nonterminal, we get:

(number)+number*number

This is a valid arithmetic expression as generated by grammar.

Given a grammar G with start symbol S, if there is some sequence of production that when applied to the initial string S, result in the string s, then s is in L (G). the language of the grammar.

cab = Taxicab(5,-8)

cab.move_x(3)

cab.move_y(-4)

cab.move_x(-1)

print(cab.odometer) # will print 8 3+4+1 = 8

Final answer:

The Taxicab class in Python should have private data members for x-coordinate, y-coordinate, and the odometer. It includes an initializer, get methods for each data member, and methods to move the taxicab horizontally and vertically, updating the odometer with each movement.

Explanation:

The student's question pertains to writing a Python class named Taxicab which models a taxicab's movements and odometer readings. To implement this, you would define the class with private data members for the x-coordinate, y-coordinate, and odometer reading. The odometer should track the total distance driven rather than the Euclidean distance from the start point. The class should have an init method to initialize these values, where the x and y coordinates are set by provided parameters and the odometer starts at zero. Additionally, there should be get methods for each of these private data members to allow access to their values. Movement methods move_x and move_y should be implemented to handle horizontal and vertical movements, respectively, and the odometer should be updated accordingly based on the magnitude of the movement.

Answer:

a) Number of available devices = 2

b) Remaining need for job 1 = 2

Remaining need for job 2 = 7

Remaining need for job 3 = 3

Remaining need for job 4 = 2

c) The system is safe

Explanation:

a) Calculate the number of available devices

Number of available devices = (Maximum number of devices) - (Total number of devices allocated)

Maximum number of devices  = 18

Total number of allocated devices = (6 + 2 + 5 + 3)

Total number of allocated devices = 16

Number of available devices = 18 - 16

Number of available devices = 2

b) Determine the remaining needs for each job in each system

Remaining needs = (Maximum Required - Number of devices allocated)

For Job 1

Remaining need = 8 - 6 = 2

For Job 2

Remaining need = 9 - 2 = 7

For Job 3

Remaining need = 8 - 5 = 3

For Job 4

Remaining need = 5 - 3 = 2

c) Determine whether the system is safe or unsafe

For the system to be safe, Need ≤ Available

Where New Available = Available + Allocation

For Job 1

Need = 2

Available devices = 2

2 ≤ 2   (Job 1 is safe)

New available = 2 + 6 = 8

For Job 2

Need = 7

Available devices = 8

7 ≤ 8   (Job 2 is safe)

New available = 2 + 8 = 10

For Job 3

Need = 3

Available devices = 10

3 ≤ 10   (Job 3 is safe)

New available = 5 + 10 = 15

For Job 4

Need = 2

Available devices = 15

2 ≤ 15   (Job 2 is safe)

New available = 3 + 15 = 18

Since all the jobs are safe, the system is safe

Answer: A. Uses third-party CA's to validate a users identity.

Explanation:

A digital certificate is a binding electronic document used in the exchange of messages between a sender and receiver across the internet. It is useful in validating the identities of all users so that none can deny either sending or receiving a message. It also offers some protection to the data sent and received.

Certification Authorities are recognized bodies who have the responsibility of ensuring the true identities of users. After achieving this they then issue a certificate that can serve as a guarantee. A public key is present in the certificate which only the true users can access.

These Certification Authorities would then confirm that the key and digital signature matches the identities of the users.

Answer:

uses third-party CAs to validate a user's identity.

Explanation:

Digital certificate is an electronic file which can be used to verify the identity of a party on the Internet. A digital certificate can be likened to an electronic passport of the internet.

It is issued by an organization called a certificate authority (CA).

A digital certificate system uses a trusted third party (certification authority), to validate a user's identity.

Explanation:

Given that:

Consider the MIPS assembly language code segment given below.

I1: addi $s3, $s2, 5

I2: sub $s1, $s3, $s4

I3: add $s3, $s3, $s1

I4: Iw $s2, 0($s3)

I5: sub $s2, $s2, $s4

I6: sw $s2, 200($s3)

I7: add $s2, $s2, $s4

(a) Identify the data dependency in the following code:

RAW - Read after write: This dependency occurs when instruction I2 tries to read register before instruction I1 writes it.

WAW - Write after write: This dependency occurs when instruction I2 tries to write register before instruction I1 writes it

• Read after write (RAW)

I1: addi $s3, $s2, 5

I2: sub $s1, $s3, $s4

• Read after write (RAW)

I2: sub $s1, $s3, $s4

I3: add $s3, $s3, $s1

• Write after write (WAW)

I4: lw $s2, 0($s3)

I5: sub $s2, $s2, $s4

• Read after write (RAW)

I5: sub $s2, $s2, $s4

I6: sw $s2, 200($s3)

(b) Data hazards which can be solved by forwarding:

(1) Read after write (RAW)

I1: addi $s3, $s2, 5

I2: sub $s1, $s3, $s4

addi $s3, $s2,5 IF ID EXE MEM WB

sub $51, $s3, $s4 IF ID EXE MEM WB

(2) Read after write (RAW)

I2: sub $s1, $s3, $s4

I3: add $s3, $s3, $s1

sub $51, $s3. $54 IF | ID EXE |MEM WB

add $s3, $s3, $s1 IF | ID EXE | MEM | WB

(3) Read after write (RAW)

I5: sub $s2, $s2, $s4

I6: sw $s2, 200($s3)

sub $52, $s2, $54 IF ID |EXE MEM | WB

sw $52, 200($s3) IF ID EXE MEM WB

(c) Data hazards which can lead to pipeline stall:

• Write after write (WAW)

I4: lw $s2, 0($s3)

I5: sub $s2, $s2, $s4

lw $s2, 0($s3) IF ID EXE MEM WB

sub $s2, $s2, $s4 IF ID Stall EXE | MEM | WB

Answer:

See explaination for the details.

Explanation:

PC can be any valid value that is divisible by 4. In that case, lets pick 20000.

We can pick any instruction dat writes to a register. Lets pick addi.

The destination register number must be odd so that it has good value of 1. The opposite of the stock-add-value we want to test for. Lets go ahead and pick register 9.

Make register 9 have a value of 20 and register 9 jas a value of 25 prior to the add instruction.

addi. $9, zero, 22

When the value read from register 8 after the add instruction is 22, we know that we have found the fault.

Final answer:

A test to determine a stuck-at-0 fault in a CPU involves preloading specific values into the PC, registers, and instruction memory, executing an instruction, and checking if the expected values are reflected post-execution. A failure to update a signal from 0 suggests a stuck-at-0 fault. This test is part of the broader endeavor of programming and diagnostics within computer engineering.

Explanation:

To design a test that determines if there is a stuck-at-0 fault on a signal within a Central Processing Unit (CPU), one could start by setting the Program Counter (PC), registers, and memory to specific non-zero values, execute an instruction that would change the state of the signal in question, and then verify if the expected changes occur.

For instance, if testing a register expected to be set to a value of 1 by an instruction, you might initialize the instruction memory with an instruction like 'SET REGISTER' to the non-zero value, and the register itself with 0. Once the instruction executes, if the register does not reflect the value that was written to it, this suggests a possible stuck-at-0 fault. This kind of fault means that no matter what value is intended for that signal, it always reads as 0, which indicates a malfunctioning component inside the CPU.

Answer:

def select_short_strings(string_list):

   new_list = []

   for s in string_list:

       if len(s) < 20:

           new_list.append(s)

   return new_list

lst = ["apple", "I am learning Python and it is fun!", "I love programming, it is easy", "orange"]

print(select_short_strings(lst))

Explanation:

- Create a function called select_short_strings that takes one argument string_list

Inside the function:

- Initialize an empty list to hold the strings that are less than 20

- Inside the loop, check the strings inside string_list has a length that is smaller than 20. If found one, put it to the new_list.

- When the loop is done, return the new_list

- Create a list to check and call the function

Answer:

# the solution function is defined

# it takes a list as parameter

def solution(string_list):

# an empty new list is initialized

new_list = []

# a loop that loop through the splitted_list

# it checks if the length of each string is less than 20

# if it is less than 20

# it is attached to the new list

for each_string in string_list:

if(len(each_string) < 20):

new_list.append(each_string)

# the new list is printed

print(new_list)

# the function is called with a sample list

solution(["The", "player", "determined", "never", "compromised"])

Explanation:

The program is written in Python and it is well commented.

A diver's score in diving is calculated by taking the middle five scores from judges, summing them up, multiplying by the dive's degree of difficulty, and then multiplying by 0.6. A computer program designed to calculate these scores would need to incorporate methods for each step of this process.

The sport of diving involves judges awarding scores to divers based on their performance. To calculate a diver's score, a computer program must follow these steps:

This scoring system ensures that outliers do not disproportionately affect the diver's score and that the degree of difficulty is appropriately factored into the final score, producing a fair assessment of the performance. The computer program must include methods to perform each of these tasks, ensuring accurate point tallies and final calculations for each dive.

Answer:

import java.util.Scanner;

public class StrictlyIdentical

{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 int[] list1 = new int[5];

 int[] list2 = new int[5];

 System.out.println("Enter the numbers for list1: ");

 for (int i=0; i<5; i++) {

        list1[i] = input.nextInt();

    }

    System.out.println("Enter the numbers for list2: ");

    for (int i=0; i<5; i++) {

        list2[i] = input.nextInt();

    }

 if (equals(list1, list2))

     System.out.println("the lists are strictly identical.");

 else

     System.out.println("the two lists are not strictly identical.");

}

public static boolean equals(int[] array1, int[] array2) {

    boolean isIdentical = true;

    for (int i=0; i<5; i++) {

        if (array1[i] != array2[i])

            isIdentical = false;

    }

    return isIdentical;

}

}

Explanation:

Create a function called equals that takes two parameters, array1, and array2

Initialize the isIdentical as true, this will be our control variable to change its value if two arrays are not identical

Create a for loop that iterates through the arrays. If corresponding elements of the arrays are not equal, set isIdentical as false.

When the loop is done, return the isIdentical

Inside the main:

Declare two arrays

Ask the user to enter numbers for the arrays using for loop

Check if two arrays are identical using the equal function. Print the appropriate message
