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.

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.

Answer:

a)

Account account = new Account();

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.

Explanation:

because they need to protect the organization's information

Answer:

Here is the Python and C++ program.

Python program:

gallons_paint=0.0  #declare and initialize gallons_paint  

wall_area = float(input())  #prompts user to enter wall area

gallons_paint = wall_area / 350  #formula to compute gallons of paint needed to cover the given square feet of walls

print(gallons_paint) #display the result

C++ program:

#include <iostream> //to use input output functions

using namespace std; //to identify objects like cin cout

int main(){ //start of main() function body

   float wall_area,gallons_paint=0; //declare variables

   cin>>wall_area; //reads input wall area from user

   gallons_paint=wall_area/350; //formula to compute gallons of paint needed to cover the given square feet of walls

   cout<<gallons_paint;} //print the result

Explanation:

The program prompts the user to enter the area of wall and stores the input value in wall_area

Suppose the user enters 250 as wall area

The the formula gallons_paint=wall_area/350; works as follows:

gallons_paint = wall_area/350;

                         = 250/350

                         = 0.71428

gallons_paint  = 0.71428

So the output is:

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

Here are the methods:

a) count

def count(object, list):  

   counter = 0

   for i in list:

       if i == object:

           counter = counter + 1

   return counter

b) in : return True if the item is in the list

def include(object, list):  

   for i in list:

       if i == object:

           return True

   return False

c)  reverse

def reverse(list):

   first = 0            

   last = len(list)-1    

   while first<last:

       list[first] , list[last] = list[last] , list[first]

       first = first + 1

       last = last - 1

   return list

d) index: return -1 if the item is not in the list  

def index(object, list):

   for x in range(len(list)):

       if list[x] == object:

           return x

   return -1

e)  insert

def insert(object, index, list):

   return list[:index] + [object] + list[index:]

Explanation:

a)

The method count takes object and a list as parameters and returns the number of times that object appears in the list.

counter variable is used to count the number of times object appears in list.

Suppose

list = [1,1,2,1,3,4,4,5,6]

object = 1

The for loop i.e. for i in list iterates through each item in the list

if condition if i == object inside for loop checks if the item of list at i-th position is equal to the object.  So for the above example, this condition checks if 1 is present in the list. If this condition evaluates to true then the value of counter is incremented to 1 otherwise the loop keeps iterating through the list searching for the occurrence of object (1) in the list.

After the complete list is moved through, the return counter statement returns the number of times object (i.e. 1 in the example) occurred in the list ( i.e. [1,1,2,1,3,4,4,5,6]  ) As 1 appears thrice in the list so the output is 3.

b)  

The method include takes two parameters i.e. object and list as parameters and returns True if the object is present in the list otherwise returns False. Here i have not named the function as in because in is a reserved keyword in Python so i used include as method name.

For example if list = [1,2,3,4] and object = 3

for loop for i in list iterates through each item of the list and the if condition if i == object checks if the item at i-th position of the list is equal to the specified object. This means for the above example the loop iterates through each number in the list and checks if the number at i-th position in the list is equal to 3 (object). When this if condition evaluates to true, the method returns True as output otherwise returns False in output ( if 3 is not found in the list). As object 3 is present in the list so the output is True.

c) reverse method takes a list as parameter and returns the list in reverse order.

Suppose list = [1,2,3,4,5,6]

The function has two variables i.e. first that is the first item of the list and last which is the last item of the list. Value of first is initialized to 0 and value of last is initialized to len(list)-1 where len(list) = 6 and 6-1=5 so last=5 for the above example. These are basically used as index variables to point to the first and last items of list.

The while loop executes until the value of first exceeds that of last.

Inside the while loop the statement list[first] , list[last] = list[last] , list[first]  interchanges the values of elements of the list which are positioned at first and last. After each interchange the first is incremented to 1 and last is decremented to 1.

For example at first iteration:

first = 0

last = 5

list[0] , list[5] = list[5] , list[0]

This means in the list [1,2,3,4,5,6] The first element 1 is interchanged with last element 6. Then the value of first is incremented and first = 1, last = 4 to point at the elements 2 and 5 of the list and then exchanges them too.

This process goes on until while condition evaluates to false. When the loop breaks  statement return list returns the reversed list.

d) The method index takes object and list as parameters and returns the index of the object/item if it is found in the list otherwise returns -1

For example list = [1,2,4,5,6] and object = 3

for loop i.e.  for x in range(len(list)):  moves through each item of the list until the end of the list is reached. if statement  if list[x] == object:  checks if the x-th index of the list is equal to the object. If it is true returns the index position of the list where the object is found otherwise returns -1. For the above examples 3 is not in the list so the output is -1  

e) insert

The insert function takes as argument the object to be inserted, the index where the object is to be inserted and the list in which the object is to be inserted.

For example list = [0, 1, 2, 4, 5, 6] and object = 3 and index = 3

3 is to be inserted in list  [1,2,4,5] at index position 3 of the list. The statement:

return list[:index] + [object] + list[index:]

list[:index] is a sub list that contains items from start to the index position. For above example:

list[:index] = [0, 1, 2]

list[index:] is a sub list that contains items from index position to end of the list.

list[index:] = [4, 5, 6]

[object] = [3]

So above statement becomes:

[0, 1, 2] + [3] + [4, 5, 6]

So the output is:

[0, 1, 2, 3, 4, 5, 6]
