Correct question:

What is the missing line?

>>> myDeque = deque('math')

>>> myDeque

deque(['m', 'a', 't'])

Answer:

myDeque.pop()

Explanation:

The double ended queue, deque found in the python collection module is very similar to a python list and can perform operations such as delete items, append and so on.

In the program written above, the missing line is the myDeque.pop() as the pop() method is used to delete items in the created list from the right end of the list. Hence, the 'h' at the right end is deleted and we have the output deque(['m', 'a', 't'])

myDeque.popleft () deletes items from the right.

Answer:

Playfair Cipher.

Explanation:

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

The best known multiple letter encryption cipher is the Playfair Cipher, which treats digrams in the plaintext as single units and translates these units into ciphertext digrams.

In the Playfair Cipher, a 5 × 5 matrix comprising of letters is developed using a keyword and then, the matrix is used to encrypt the plaintext as a pair i.e two letters at a time rather than as a single text.

Answer:

The program is as follows:

import java.util.Scanner;

public class MyClass {

   public static Boolean isSorted(int [] arr){

       Boolean sorted = true;

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

       for(int j = i;j<arr.length;j++){

           if(arr[i]>arr[j]){

               sorted = false;

               break;

           }

       }    

       }

       return sorted;

   }

   public static void main(String args[]) {

       Scanner input = new Scanner(System.in);

       int n;

       System.out.print("Length of array: ");

       n = input.nextInt();

       int[] arr = new int[n];

       System.out.println("Enter array elements:");

       for(int i = 0; i<n;i++){

           arr[i] = input.nextInt();

       }

      Boolean chk = isSorted(arr);

     System.out.print(chk);

   }

}

Explanation:

The method begins here

This line defines a method named isSorted

   public static Boolean isSorted(int [] arr){

This line declares a boolean variable and initializes it to true

       Boolean sorted = true;

The next two iterations iterate through elements of the array

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

       for(int j = i;j<arr.length;j++){

This compares an array element with next elements (to the right)

           if(arr[i]>arr[j]){

If the next element is smaller than the previous array element, then the array is not sorted

               sorted = false; The boolean variable is updated to false

               break; This breaks the loop

           }

       }    

       }

This returns true or false, depending on the order of the array

       return sorted;

   }

The main method begins here

public static void main(String args[]) {

       Scanner input = new Scanner(System.in);

       int n;

This prompts user for length of array

       System.out.print("Length of array: ");

This gets length of array from user

       n = input.nextInt();

This declares an array

       int[] arr = new int[n];

This prompts user for array elements

       System.out.println("Enter array elements:");

The following iteration gets the array elements

       for(int i = 0; i<n;i++){

           arr[i] = input.nextInt();

       }

This calls the isSorted array      

     Boolean chk = isSorted(arr);

This prints true or false, depending if the array is sorted or not

     System.out.print(chk);      

   }

Answer:

The program in recursion is:

def find_max(nums):

    if len(nums) == 0:

         return "None"

    elif len(nums) == 1:

         return nums[0]

    else:

         return max(nums[0],find_max(nums[1:]))

Explanation:

This line defines the function

def find_max(nums):

This checks if the list is empty.

    if len(nums) == 0:

If yes, it returns "None"

         return "None"

If the list has just one element

    elif len(nums) == 1:

It returns the only element as the maximum

         return nums[0]

If the list has numerous elemente

    else:

The maximum is determined recursively

         return max(nums[0],find_max(nums[1:]))

To the (b) part:

This program does not necessarily need to be done recursively because the max built-in function can be used to determine the maximum of the list in just one line of code and it is more efficient.

Required

Which term removes 7:10 from the dictionary

To remove an item from a dictionary in Python, you follow the syntax below:

[dictionary-name].pop(key)

In this case:

The dictionary name is info and the key is 7

So, the term that implements the syntax is: info.pop(7)

After the instruction info.pop(7) is executed, the content of the dictionary becomes: {3: 10.4:23, 11:31}

Explanation:

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

Ethernet ensures that signals on a shared network never interfere with each other and become unreadable through the use of encapsulation and standard encryption protocols.

In Computer Networking, encapsulation can be defined as the process of adding a header to a data unit received by a lower layer protocol from a higher layer protocol during data transmission. This ultimately implies that, the header (segment) of a higher layer protocol such as an application layer, is the data of a lower layer such as a transportation layer in the Transmission Control Protocol and Internet Protocol (TCP/IP).

The TCP/IP model comprises of four (4) layers;

1. Application layer: this is the fourth layer of the TCP/IP model. Here, the data unit is encapsulated into segments and sent to the transport layer.

2. Transport layer (layer 3): it receives the segment and encapsulates it into packets and sends to the internet layer.

3. Internet layer (layer 2): packets are encapsulated into frames.

4. Network layer (layer 1): frames are then converted into bits and sent across the network (LAN).

Hence, the data unit encapsulated inside a packet is known as segment, which is typically referred to as packet segmentation.

Additionally, these data, segments, packets, frames and bits transmitted across various layers are known as protocol data units (PDUs).

Answer:

The program in Python is as follows:

for number in range(6):

    print(number, end=' ')

Explanation:

From the program, the range is 0 to 5.

The following line iterates from 0 to 5 using "number" as its iterating variable

for number in range(6):

This prints each number in the range followed by a blank space

    print(number, end=' ')

The for loop with a range function that prints the following output 0 1 2 3 4 5 is as follows:

for i in range(6):

   print(i)

The code is expected to print the values 0 1 2 3 4 5.

A for loop is used to loop through the range values of 6. The range value of 6

are 0 1 2 3 4 and 5.

The range function is used as required to get the value.

Finally, we print the looped values

The code will output 0 1 2 3 4 5

Answer:

postincrement.

Explanation:

In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.

Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.

For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.

The postincrement operator increases the value of the variable by 1 after the original value is used in the expression in which the variable appears.
