Create a class named CarRental that contains fields that hold a renter's name, zip code, size of the car rented, daily rental fee, length of rental in days, and total rental fee. The class contains a constructor that requires all the rental data except the daily rate and total fee, which are calculated bades on the sice of the car; economy at $29.99 per day, midsize at 38.99$ per day, or full size at 43.50 per day. The class also includes a display() method that displays all the rental data. Create a subclass named LuxuryCarRental. This class sets the rental fee at $79.99 per day and prompts the user to respond to the option of including a chauffer at $200 more per day. Override the parent class display() method to include chauffer fee information. Write an application named UseCarRental that prompts the user for the data needed for a rental and creates an object of the correct type. Display the total rental fee. Save the files as CarRental.java, LuxaryCarRental.java, and UseCarRental.java.

The Adjacent Coins Problem Published on 2017-08-30 Consider N coins aligned in a row. Each coin is showing either heads or tails. The adjacency of these coins is the number of adjacent pairs of coins with the same side facing up. Write a program that given a non-empty zero-indexed array A consisting of N integers representing the coins, returns the maximum possible adjacency that can be obtained by reversing exactly one coin (that is, one of the coins must be reversed). Consecutive elements of array A represent consecutive coins in the row. Array A contains only 0s and/or 1s:
Answers
Answer:
Here is the JAVA code:
public class Main{
public static int solution(int[] A) { //method that takes non-empty array A consisting of 0s and 1s
int N = A.length; // number of 0s and 1s in array A
int r = 0; //result of adjacency
for (int i = 0; i < N - 1; i++; ) { // iterates through A
if (A[i] == A[i + 1]) //if i-th element of A is equal to (i+1)th element
r = r + 1; } //add 1 to the count of r
if (r == N-1) //for test cases like {1,1}
{return r-1; }
int max = 0; //to store maximum possible adjacency
for (int i = 0; i <N; i++) { //iterates through array
int c = 0;
if (i > 0) { //starts from 1 and covering the last
if (A[i-1] != A[i]) //checks if i-1 element of A is not equal to ith element of A
c = c + 1; //adds 1 to counter variable
else
c = c - 1; } //decrements c by 1
if (i < N - 1) {//starting with 0
if (A[i] != A[i + 1]) //checks if ith element of A is not equal to i+1th element of A
c = c + 1; //adds 1 to counter variable
else
c = c - 1; } //decrements c by 1
max = Math.max(max,c); } //finds the maximum of max and c
return r + max; } //returns result + maximum result
public static void main(String[] args) {
int[] A = {1, 1, 0, 1, 0, 0}; //sample array to test the method
System.out.println(solution(A));} } //calls the method passing array to it
Explanation:
The program works as follows:
A[] = {1, 1, 0, 1, 0, 0}
N = A.length
N = 6
The A has the following elements:
A[0] = 1
A[1] = 1
A[2] = 0
A[3] = 1
A[4] = 0
A[5] = 0
Program iterates through array A using for loop. Loop variable i is initialized to 0
if condition if (A[i] == A[i + 1]) checks
if (A[0] == A[0 + 1])
A[0] = 1
A[0 + 1] = A[1] = 1
They both are 1 so they are equal
r = r + 1;
Since the above if condition is true so 1 is added to the value of r Hence
r = 1
At each iteration of the loop the if condition checks whether the adjacent elements of A are equal. If true then r is incremented to 1 otherwise not.
So after all the iterations value of r = 2
if (r == N-1) evaluates to false because r=2 and N-1 = 5
So program moves to the statement:
for (int i = 0; i <N; i++)
This loop iterates through the array A
if (i > 0) condition checks if value of i is greater than 0. This evaluates to false and program control moves to statement:
if (i < N - 1) which makes if(0<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[0] != A[0 + 1]) -> if (A[0] != A[1])
We know that
A[0] = 1
A[1] = 1
So this evaluates to false and else part is executed:
value of c is decremented to 1. So c=-1
max = Math.max(max,c) statement returns the max of max and c
max = 0
c = -1
So max = 0
value of i is incremented to 1 so i = 1
At next step:
if (i < N - 1) which makes if(1<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[1] != A[1 + 1]) -> if (A[1] != A[2])
A[1] = 1
A[2] = 0
So the statement evaluates to true and following statement is executed
c = c + 1; The value of c is incremented to 1. So
c = -1 + 1
Hence
Hence c= 0, max = 0 and i = 2
next step:
if (i < N - 1) which makes if(2<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[2] != A[2 + 1]) -> if (A[2] != A[3])
A[2] = 0
A[3] = 1
So the statement evaluates to true and following statement is executed
c = c + 1; The value of c is incremented to 1. So
c = 0 + 1
c = 1
Hence
The statement max = Math.max(max,c) returns the max of max and c
max = 0
c = 1
So max = 1
Hence c= 1, max = 1 and i = 3
next step:
if (i < N - 1) which makes if(3<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[3] != A[3 + 1]) -> if (A[3] != A[4])
A[3] = 1
A[4] = 0
So the statement evaluates to true and following statement is executed
c = c + 1; The value of c is incremented to 1. So
c = 1 + 1
c = 2
Hence
The statement max = Math.max(max,c) returns the max of max and c
max = 1
c = 2
So max = 2
Hence c= 2, max = 2 i = 4
next step:
if (i < N - 1) which makes if(4<5) This evaluates to true and program control moves to statement
if (A[i] != A[i + 1]) which means:
if (A[4] != A[4+ 1]) -> if (A[4] != A[5])
A[4] = 0
A[5] = 0
So this evaluates to false and else part is executed:
value of c is decremented to 1. So c=1
max = Math.max(max,c) statement returns the max of max and c
max = 2
c = 1
So max = 2
value of i is incremented to 1 so i = 5
next step:
if (i < N - 1) which makes if(5<5) This evaluates to false
if (i > 0) evaluates to true so following statement executes:
if (A[i-1] != A[i])
if (A[5-1] != A[5])
if (A[4] != A[5])
A[4] = 0
A[5] = 0
This statement evaluates to false so else part executes and value of c is decremented to 1
Hence
max = 2
c = 0
So max = 2
value of i is incremented to 1 so i = 6
The loop breaks because i <N evaluates to false.
Program control moves to the statement:
return r + max;
r = 2
max = 2
r + max = 2+2 = 4
So the output of the above program is:
4

Describe how asymmetric encryption is used to send a message from User A to User B that assures data confidentiality, authentication, and integrity. Be specific as to the keys used and how they achieve the three goals.
Answers
Answer:
Find the explanation below.
Explanation:
Asymmetric encryption is a system of communication in technology between two parties where keys which are variable values coined by an algorithm are used to encrypt and decrypt the messages between the sender and receiver. The two types of keys used in this process are the public and private keys. The public keys can be used by anyone to encrypt messages which are then sent to the receiver who decrypts the message using his private keys. The private keys on the other hand are only shared by the person who first set up the key. In sending messages this way, the receiver's public key is gotten from a public directory, and the message encrypted by the sender. The receiver can then decrypt the message using his private keys. But if the message is encrypted using a private key, it is decrypted by the receiver with a public key.
The one-way nature of this style of communication ensures data integrity and confidentiality since users are not required to disclose their keys and only the two parties can access the message. The two end users also preserve the right to authenticate the keys. The transport layer security protocol makes use of asymmetric encryption.

In the above code, the "f1 and f2" variable is used for input value from the user end, in which it stores the file names. In the next step, the "file1 and file2" variable is declared that uses the open method to open the file. In the next line, the"d1 and d2" variable is declared for reads file by using the "readlines" method. Then, if block is used that uses the "d1 and d2" variable to match the file value if it matches it will print "yes", otherwise a for loop is declared, that prints files mismatch values.Answer:
first = input("enter first file name: ")
second = input("enter second file name: ")
file_one = open(first, 'r')
file_two = open(second, 'r')

b)
Account account = new Account(firstName, age);
c)
account.Age = newAge;
d)
int count = Account.Count;
Explanation:
a)
new is the keyword which is used to create an object.
Account is the class name.
account is the name of an object of class Account.
account object is created to access the class Account.
Account() is the constructor of Account class. This is the default constructor and it has no parameters. Constructor has the same name as class. When a account object is created, constructor Account will be invoked.
b)
Account is the class name.
account is the name of an object of class Account.
Account() is the constructor of Account class. This is the parameterized constructor and it has two parameters i.e. firstName and age. Constructor has the same name as class. When a account object is created, constructor Account will be invoked.
c)
account.Age = newAge;
Here account is the object name. The Age property to access and update the private field of the Account class is set to the variable named newAge.
d)
This int count = Account.Count; statement gets the value of a public static field named Count that’s defined in the Account class, and stores the value in a new int variable named count.

The web development team is having difficulty connecting by ssh to your local web server, and you notice the proper rule is missing from the firewall. What port number would you open on your webserver?
a. Port 21
b. Port 22
c .Port 25
d. Port 80
e. Port 443
Answers
Answer:
Option b (Port 22) seems to the appropriate choice.
Explanation:
Below seem to be some measure you should take to correct this mistake.
Verify whether Droplet's host IP address seems to be right. Verify existing connection supports communication over all the utilized SSH port. Any access points can be able to block port 22 and sometimes customized SSH. For illustration, you could do this by checking different hosts who used the same port, using only a recognized working SSH connection. These could help you identify unless the current problem is not particular to clients' Droplet. Authenticate the Droplet configuration settings. Verify that they're not being configured to DROP 's preferred policy, and do not apply the port to require connectivity.The SSH server also operates on port 22, by default.
Other choices don't apply to the specified scenario. So that the argument presented above will be appropriate.
The port number would you open on your webserver is Port 22
For better understanding let's explain SSH means.
Service Name and Transport Protocol Port Number Registry. where the service name is Secure Shell (SSH) Protocol and it has the port number of 22 therefore this mean that SSH will only work with port 22 using it for other port will only result in difficulty in connection. SSH has other names like Secure Shell or Secure Socket Shell. it is known as a network protocol that helps its users with system administrator.From the above we can therefore say that the answer The port number would you open on your webserver is Port 22, is correct

A TCP entity opens a connection and uses slow start. Approximately how many round-trip times are required before TCP can send N segments
Answers
Answer:
Round trip times required = log2N
Explanation:
The round-trip times required before TCP can send N segments using a slow start is log2N. we can arrive at this by looking at the mode of operation of TCP which is at the 1st time of using a TCP it starts the congestion window as 1 then it sends an initial segment. When the acknowledgement of the initial segment arrives, TCP increases the congestion window to 2 and then sends 2 segments, When the 2 acknowledgements of the segments sent out arrives, they each increase the congestion window by one, thereby increasing the congestion window to 4 . therefore it takes log2N round trips before TCP can send N segments

Answer:
a) An ARRAY ( 3 )
B) relatively INSENSITIVE ( 7 )
c) a HYBRID ( 4 )
Explanation:
They both used an array based implementation in the standard form and are both relatively insensitive to the order of the data. The main similarity is that each one creates an environment in which a hybrid strategy works more efficiently.

5.15 LAB: Count input length without spaces, periods, or commas Given a line of text as input, output the number of characters excluding spaces, periods, or commas. Ex: If the input is:
Answers
Answer:
Following are the code to this question:
userVal = input()#defining a variable userVal for input the value
x= 0#defining variable x that holds a value 0
for j in userVal:#defining for loop to count input value in number
if not(j in " .,"):#defining if block that checks there is no spaces,periods,and commas in the value
x += 1#increment the value of x by 1
print(x)#Print x variable value
Output:
Hello, My name is Alex.
17
Explanation:
In the above-given code, a variable "userVal" is defined that uses the input method for input the value from the user end, in the next line, an integer variable "x" is defined, hold value, that is 0, in this variable, we count all values.
In the next line, for loop is defined that counts string value in number and inside the loop an if block is defined, that uses the not method to remove spaces, periods, and commas from the value and increment the value of x by 1. In the last step, the print method is used, which prints the calculated value of the "x" variable.
Answer:
Explanation:#include <iostream>
#include<string>
using namespace std;
int main()
{
string str;
cout<<"Enter String \n";
getline(cin,str);/* getLine() function get the complete lines, however, if you are getting string without this function, you may lose date after space*/
//cin>>str;
int count = 0;// count the number of characeter
for (int i = 1; i <= str.size(); i++)//go through one by one character
{
if ((str[i]!=32)&&(str[i]!=44)&&(str[i]!=46))//do not count period, comma or space
{
++ count;//count the number of character
}
}
cout << "Number of characters are = "; //display
cout << count;// total number of character in string.
return 0;
}
}

What is project planning?The discipline of project planning focuses on how to complete a project within a predetermined timeframe, often with predetermined stages and resources. According to one method of project planning, the first stage is to set definable goals. scheduling the deliverables definition.
A project plan is made in order to effectively provide a result for the internal or external client. Project deliverables include, for instance, software products, design documentation, and other assets listed in the project plan. Deliverables for projects are frequently asked for as software products.
A project plan is a group of official documents that describe the execution and control phases of the project. The strategy considers risk management, resource management, and communications in addition to scope, cost, and schedule baselines.

The sternum or breastbone is a long flat bone located in the central part of the chest.
In the middle of the chest, there is a long, flat bone known as the sternum or breastbone. It forms the front of the rib cage and is joined to the ribs by cartilage, assisting in the protection of the heart, lungs, and major blood arteries from harm. It is one of the longest and largest flat bones in the body, somewhat resembling a necktie. The manubrium, body, and xiphoid process are its three regions.
Therefore, the sternum or breastbone is a long flat bone located in the central part of the chest.

Declare a struct named PatientData that contains two integer data members named heightInches and weightPounds. Sample output for the given program:Patient data: 63 in, 115 lbs#include using namespace std;/* Your solution goes here */int main() {PatientData lunaLovegood;lunaLovegood.heightInches = 63;lunaLovegood.weightPounds = 115;cout << "Patient data: "<< lunaLovegood.heightInches << " in, "<< lunaLovegood.weightPounds << " lbs" << endl;return 0;}
Answers
Answer:
struct PatientData{
int heightInches, weightPounds;
};
Explanation:
In order to declare the required struct in the question, you need to type the keyword struct, then the name of the struct - PatientData, opening curly brace, data members - int heightInches, weightPounds;, closing curly brace and a semicolon at the end.
Note that since the object - lunaLovegood, is declared in the main function, we do not need to declare it in the struct. However, if it was not declared in the main, then we would need to write lunaLovegood between the closing curly brace and the semicolon.

Describe and compare imperative (C), functional (SML) and logic (Prolog) programming paradigms.
Answers
Answer:
Answered below
Explanation:
Imperative programming paradigm is a paradigm in which the programmer tells the machine how to change its state. It is divided into procedural programming, where programs are grouped as procedures, and object-oriented, where programs are grouped together with the properties they operate on.
Imperative paradigm is efficient, familiar and popular compared to others.
Functional programming paradigm implements all instructions as functions, in a mathematical sense. They take on an argument and return a single solution. The advantage of this, compared to other paradigms, is its abstraction and independence.
Logical programming, like functional programming, incorporates a declarative approach to problem solving. All known facts are first established before queries are made. Advantage of this paradigm is that programming steps are kept to a minimum.
