Answer:

A program in C++ was written to prompts the user to enter the area of the flat cardboard.

Explanation:

Solution:

The C++ code:

#include <iostream>

#include <iomanip>

#include <cmath>

using namespace std;

double min(double,double);

void max(double,double,double&,double&);

int main()

{double area,length,width=.001,vol,height,maxLen,mWidth,maxHeight,maxVolume=-1;

cout<<setprecision(3)<<fixed<<showpoint;

cout<<"Enter the area of the flat cardboard: ";

cin>>area;

while(width<=area)

{length=area/width;

max(length,width,vol,height);

if(vol>maxVolume)

{maxLen=length;

mWidth=width;

maxHeight=height;

maxVolume=vol;

}

width+=.001;

}

cout<<"dimensions of card to maximize the cardboard box which has a volume "

<<maxVolume<<endl;

cout<<"Length: "<<maxLen<<"\nWidth: "<<maxLen<<endl;

cout<<"dimensions of the cardboard box\n";

cout<<"Length: "<<maxLen-2*maxHeight<<"\nWidth: "

<<mWidth-2*maxHeight<<"\nHeight: "<<maxHeight<<endl;

return 0;

}

void max(double l,double w,double& max, double& maxside)

{double vol,ht;

maxside=min(l,w);

ht=.001;

max=-1;

while(maxside>ht*2)

{vol=(l-ht*2)*(w-ht*2)*ht;

if(vol>max)

{max=vol;

maxside=ht;

}

ht+=.001;

}

}

double min(double l,double w)

{if(l<w)

return l;

return w;

}

Note:  Kindly find the output code below

/*

Output for the code:

Enter the area of the flat cardboard: 23

dimensions of card to maximize the cardboard box which has a volume 0.023

Length: 4.796

Width: 4.796

dimensions of the cardboard box

Length: 4.794

Width: 4.794

Height: 0.001

*/

Answer:

t

Explanation:

Answer:

The program is written using PYTHON SCRIPT below;

N=int(input(" Enter number of Rows you want:"))

M=[] # this for storing the matrix

for i in range(N):

l=list(map(int,input("Enter the "+str(i+1)+" Row :").split()))

M.append(l)

print("The 2D Matrix is:\n")

for i in range(N):

print(end="\t")

print(M[i])

W=[] # to store the first non zero elemnt index

T=[] # to store that value is positive or negative

L=len(M[0])

for i in range(N):

for j in range(L):

if (M[i][j]==0):

continue

else:

W.append(j) # If the value is non zero append that postion to position list(W)

if(M[i][j]>0): #For checking it is positive or negative

T.append(+1)

else:

T.append(-1)

break

print()

print("The first Non Zero element List [W] : ",end="")

print(W)

print("Positive or Negative List [T] : ",end="")

print(T)

Explanation:

In order for the program to determine a set of test cases it takes in input of 2D matrix in an N numbet of rows.

It goes ahead to program and find the column index of the first non-zero value for each row in the matrix A, and also determines if that non-zero value is positive or negative. The If - Else conditions are met accordingly in running the program.

Answer:

The reason is due to proprietary design of the Operating System (OS) which require a virtualization software to blanket or "disguise" the hardware (processor) borderlines of the computer onto which it is to be installed.

Explanation:

An Apple system that has the RISC processor and system architecture which has an operating system made entirely for the Apple system architecture

If the above Apple OS is to be installed on a windows computer, then the procedure to setup up the OS has to be the same as that used when on an Apple system, hence, due to the different processors and components of both systems, a virtualization will be be needed to be provided by a Virtual box, Parallels desktop or other virtualization software.

Answer:

The final tables in 3NF are as follows.

Project( ProjectNbr, ProjectName)

Employee( EmployeeNbr, EmployeeName, JobClass)

Job( JobClass, HourlyRate)

ProjectBilling( ProjectNbr, EmployeeNbr, HoursBilled)

Explanation:

The given table is given below.

ProjectBilling( ProjectNbr, ProjectName, EmployeeNbr, EmployeeName, JobClass, HourlyRate, HoursBilled)  

ProjectNbr -> ProjectName

EmployeeNbr -> EmployeeName  

JobClass -> HourlyRate

ProjectNbr, EmployeeNbr -> HoursBilled

1NF

1. All the fields in the given table contain only a single value. The table is in 1NF.

2NF

2. New tables are formed based on the given functional dependencies.

Project( ProjectNbr, ProjectName)

Employee( EmployeeNbr, EmployeeName)

Job( JobClass, HourlyRate)

ProjectBilling( ProjectNbr, EmployeeNbr, HoursBilled)

3. Every table is assigned a primary key which are as follows.

ProjectNbr is the primary key for Project table.

EmployeeNbr is the primary key for Project table.

JobClass is the primary key for Project table.

(ProjectNbr, EmployeeNbr) is the composite primary key for the ProjectBilling table.

4. The tables which are related to each other are linked via primary key and foreign key.

5. In the ProjectBilling table, the composite primary key, ProjectNbr, EmployeeNbr is composed of the primary keys of the Project and Employee tables, i.e., ProjectNbr and EmployeeNbr respectively.

6. Job table is related to Employee table. Hence, primary key of Job table, JobClass, is introduced as foreign key in Employee table.

Employee( EmployeeNbr, EmployeeName, JobClass)

7. Partial dependency arises when composite primary key exists and non-prime attributes (columns other than the primary key) depend on a part of the primary key, i.e., partial primary key.

In the ProjectBilling table, no partial dependency exists.

8. All the tables are in 2NF as given below.

Project( ProjectNbr, ProjectName)

Employee( EmployeeNbr, EmployeeName, JobClass)

Job( JobClass, HourlyRate)

ProjectBilling( ProjectNbr, EmployeeNbr, HoursBilled)

3NF

9. All the tables are in 2NF.

10. In every table, all non-prime attribute depend only on the primary key.

11. No transitive dependency exists, i.e., all non-prime attributes do not depend on other non-prime attributes.

12. Hence, all the conditions are satisfied and the tables are in 3NF.

Answer:

False.

Explanation:

The correct option is false that is to say the arrangement is not true. So, let us check one or two things about the RSA System.

The RSA system simply refer to as a cryptosystem that was first established in the year 1973 but was later developed in the year 1977 by Ron Rivest, Adi Shamir and Leonard Adleman.

The main use of the RSA system is for encryption of messages. It is known as a public key cryptography algorithm.

The way the algorithm should have been arranged is;

(1). Randomly select two large prime numbers p and q, which always must bekept secret.

(2). Determine the product n = pq, known as public modulus.

(3). Select an integer number E, known as the public exponent, such that (p 1)and E have no common divisors, and (q 1) and E have no commondivisors.

(4). Determine the private exponent, D, such that (ED 1) is exactly divisible by both (p 1) and (q 1). In other words, given E, we choose D such that the integer remainder when ED is divided by (p1)(q 1) is 1.

(5). Release publicly the public key, which is the pair of numbers n and E, K =(n, E). Keep secret the private key, K = (n, D).

Therefore, The way it should have been arranged in the question should have been;

(1) , (4), (2), (3 ) and ( 5).

Answer:

see explaination

Explanation:

The data is collected in a comma-separated values (CSV) format that always includes the following fields:

? date: string

? time: string

? client_ip: string

? server_ip: string

? url_stem: string

? url_query: string

? client_bytes: integer

? server_bytes: integer

What should you do?

a. Load the data as lines of text into an RDD, then split the text based on a comma-delimiter and load the RDD into DataFrame.

# import the module csv

import csv

import pandas as pd

# open the csv file

with open(r"C:\Users\uname\Downloads\abc.csv") as csv_file:

# read the csv file

csv_reader = csv.reader(csv_file, delimiter=',')

# now we can use this csv files into the pandas

df = pd.DataFrame([csv_reader], index=None)

df.head()

b. Define a schema for the data, then read the data from the CSV file into a DataFrame using the schema.

from pyspark.sql.types import *

from pyspark.sql import SparkSession

newschema = StructType([

StructField("date", DateType(),true),

StructField("time", DateType(),true),

StructField("client_ip", StringType(),true),

StructField("server_ip", StringType(),true),

StructField("url_stem", StringType(),true),

StructField("url_query", StringType(),true),

StructField("client_bytes", IntegerType(),true),

StructField("server_bytes", IntegerType(),true])

c. Read the data from the CSV file into a DataFrame, infering the schema.

abc_DF = spark.read.load('C:\Users\uname\Downloads\new_abc.csv', format="csv", header="true", sep=' ', schema=newSchema)

d. Convert the data to tab-delimited format, then read the data from the text file into a DataFrame, infering the schema.

Import pandas as pd

Df2 = pd.read_csv(‘new_abc.csv’,delimiter="\t")

print('Contents of Dataframe : ')

print(Df2)

import java.util.Scanner;

public class StudentScores

{

public static void main(String[] args) {

 Scanner scnr = new Scanner(System.in);

 final int NUM_POINTS = 4;

 int[] dataPoints = new int[NUM_POINTS];

 int controlValue;

 int i;

 controlValue = scnr.nextInt();

 for (i = 0; i < dataPoints.length; ++i) {

     dataPoints[i] = scnr.nextInt();

 }

 for (i = 0; i < dataPoints.length; ++i) {

     System.out.print(dataPoints[i] + " ");

 }

 System.out.println();

 for (i = 0; i < dataPoints.length; ++i) {

     if(dataPoints[i] < controlValue){

         dataPoints[i] = dataPoints[i] * 2;          

     }

     System.out.print(dataPoints[i] + " ");

Explanation:

*Added parts highligted.

After getting the control value and values for the array, you printed them.

Create a for loop that iterates through the dataPoints. Inside the loop, check if a value in dataPoints is smaller than the contorolValue. If it is, multiply that value with 2 and assign it to the dataPoints array. Print the elements of the dataPoints

           System.out.print(dataPoints[i] + " ");

       }

       System.out.println(); } }

Explanation:

See the additional code to accomplish the task in bold

The trick is using an if statement inside of a for loop that checks the condition (dataPoints[i]<controlValue) If true, it multiplies the element by 2

Answer:

We made use of the dynamic programming method to solve a linear-time algorithm which is given below in the explanation section.

Explanation:

Solution

(1) By making use of the  dynamic programming, we can solve the problem in linear time.

Now,

We consider a linear number of sub-problems, each of which can be solved using previously solved sub-problems in constant time, this giving a running time of O(n)

Let G[t] represent the sum of a maximum sum contiguous sub-sequence ending exactly at index t

Thus, given that:

G[t+1] = max{G[t] + A[t+1] ,A[t+1] } (for all   1<=t<= n-1)

Then,

G[0] = A[0].

Using the above recurrence relation, we can compute the sum of the optimal sub sequence for array A, which would just be the maximum over G[i] for 0 <= i<= n-1.

However, we are required to output the starting and ending indices of an optimal sub-sequence, we would use another array V where V[i] would store the starting index for a maximum sum contiguous sub sequence ending at index i.

Now the algorithm would be:

Create arrays G and V each of size n.

G[0] = A[0];

V[0] = 0;

max = G[0];

max_start = 0, max_end = 0;

For i going from 1 to n-1:

// We know that G[i] = max { G[i-1] + A[i], A[i] .

If ( G[i-1] > 0)

G[i] = G[i-1] + A[i];

V[i] = V[i-1];

Else

G[i] = A[i];

V[i] = i;

If ( G[i] > max)

max_start = V[i];

max_end = i;

max = G[i];

EndFor.

Output max_start and max_end.

The above algorithm takes O(n) time .
