Answer:

def permutations(myList: list)-> list:  

   if len(myList) <= 1:  

       return [myList]  

   perm = []  

   for i in range(len(myList)):  

      item = myList[i]  

      seglists = myList[:i] + myList[i+1:]  

      for num in permutations(seglists):  

          perm.append([item] + num)  

   return perm

data = [1,2,3]  

result = permutations(data)  

print(result)

Explanation:

The program defines a python function that returns the list of permutations. The program checks if the length of the input list is less than or equal to one. The function declaration identifies the input and output as lists.

The for loop iterate through the list and the permutations are saved in an empty list in the next loop statement. At the end of the program, the list of lists is returned.

There Will Come Soft Rains is a warning story about nuclear war and how, in the end, technology won't keep us safe. In response to the atomic bombings of Hiroshima and Nagasaki, Bradbury penned the tale.

Ray Bradbury wrote the classic science fiction short tale “There Will Come Soft Rains” in 1950. The narrative is narrated in a detached, emotionless tone, as though the events that are taking place are a normal part of everyday life.

The story's meaning can be found in the story's complete lack of human beings, not even corpses.

Soft rain rays will appear in the short story. Bradbury creates a disorganized, somewhat post-apocalyptic atmosphere. To better understand the zeitgeist of the world, he employs a variety of literary techniques.

Therefore, It's the worried tone author’s.

Answer:

EDVAC was one of the earliest electronic computers. Unlike its predecessor the ENIAC, it was binary rather than decimal, and was designed to be a stored-program computer. ENIAC inventors John Mauchly and J. Presper Eckert proposed the EDVAC's construction in August 1944.

Explanation:

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

In Linux, users are internally represented using a unique number called user ID or UID. Thus, this unique number serves as an internal identifier in the Linux Kernel and as such determines what system resources may be accessible to each user. Oftentimes, these unique numbers are not put into use but rather a name is linked with the number and are used instead.

Also, users can be organized logically into a group and are represented uniquely with a group ID or GID, which serves as a global identifier for the users.

Use guestNumber1.equals(Fernando) instead of the double equal signs. You cant compare strings with ==

Answer:

You OR expressions are wrong.

Explanation:

Rather than writing:

  if method == "Square" or "square":

You should write:

  if method == "Square" or method == "square":

The expression should evaluate to something that is true or false.

In the above case, the expression is method == "Square" or method == "square" which can are actually two sub-expressions with an or in between them:

subexpr1 or subexpr2

each of the sub-expressions should evaluate to true or false.

method == "Square" is one of those sub-expressions.

That is how an expression is broken down by the compiler.

TIP: If you would add method = method.lower() right after the input, you could simplify all the if statements by removing the uppercase variants.

Answer:

print("${:,.2f}".format(5242.83))

Explanation:

Given

$5,242.83

Required

Use an f string to output the above

The syntax of an f-string to format a number in that regard is: "${:,.2f}".format(number)

$ means that a dollar sign be printed before the required number

., means that the number be separated with commas

2f means that the number be presented in 2 decimal places

So:

"${:,.2f}".format(number) becomes

"${:,.2f}".format(5242.83)

In a print statement, the full instruction is:

print("${:,.2f}".format(5242.83))

Follows are the code to the given question:

public class Employee //defining a class Employee

{

String first_name,last_name;

Double monthly_salary;

Employee(String first_name,String last_name,Double monthly_salary)

{

   this first_name=f_name// initialize value in first_name

   this last_name = l_name; // initialize value in the last_name

    this monthly_salary = m_salary; // initialize value in the monthly_salary

if (monthly_salary < 0.0)//use if to check monthly_salary is positive

           monthly_salary = 0.0;//set value 0

}

Explanation:

In this code, a class "Employee" is declared that defines two string variables  "first_name,last_name", and one double variable "monthly_salary". In the next step, a parameterized constructor is defined that stores the value into the variable, and use if block to check "monthly_salary" is a positive. It also uses the getter and setter method to hold and return its value.

Explanation:

To resolve basic design restrictions, EBNF has also been developed.This principle was its lack of support can identify repeatings easily. It implies that popular BNF models, like the description of a sequence of replicable elements, are complicated and rely on contra intuitive logical math.

To set a list of words divided by commas (e.g. john, coffee, logic) for instance, we would like to say something like "a list is a word accompanied by a few commas or terms." Through EBNF, they may say so. However, there have been no "many" alternatives in the standard BNF format. So, to describe something such as "a list is a term or a number accompanied by a pair with notation and script," you have to say the same thing. Which functions, although it is difficult, as it specifies a variety of lists instead of a specific list.

Essentially, "john, coffee, logic is John's list, accompanied by coffees or, and logic" would be the earlier link.  That's why in Option (a):

import java.util.*;

public class MyClass{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 System.out.print("Length of array 1: ");

 int lent1 = input.nextInt();

 while(lent1 <= 0 || lent1 > 50){

     System.out.print("Length of array 1: ");

     lent1 = input.nextInt();

 }

 int[] array1 = new int[lent1];

 System.out.print("Length of array 2: ");

 int lent2 = input.nextInt();

 while(lent2 <= 0 || lent2 > 50){

     System.out.print("Length of array 2: ");

     lent2 = input.nextInt();

 }

 int[] array2 = new int[lent2];

 for(int i =0;i<lent1;i++){

     array1[i] = (int)(Math.random() * (lent1*2) + 1);

 }

 for(int i =0;i<lent2;i++){

     array2[i] = (int)(Math.random() * (lent2*2) + 1);

 }

 System.out.print("Array 1: ");

 for(int i =0;i<lent1;i++){

     System.out.print(array1[i]+" ");

 }

 System.out.println("Array 2: ");

 for(int i =0;i<lent2;i++){

     System.out.print(array2[i]+" ");

 }

}

}

Explanation:

This prompts the user for length of the first array

 System.out.print("Length of array 1: ");

This declares and gets input for the length of the first array

 int lent1 = input.nextInt();

This validates the length of first array

 while(lent1 <= 0 || lent1 > 50){

     System.out.print("Length of array 1: ");

     lent1 = input.nextInt();  }

This declares the first array

 int[] array1 = new int[lent1];

This prompts the user for length of the second array

 System.out.print("Length of array 2: ");

This declares and gets input for the length of the second array

 int lent2 = input.nextInt();

This validates the length of the second array

 while(lent2 <= 0 || lent2 > 50){

     System.out.print("Length of array 2: ");

     lent2 = input.nextInt();  }

This declares the second array

 int[] array2 = new int[lent2];

The following generates random integers between 1 and lent1*2 to array 1

 for(int i =0;i<lent1;i++){

     array1[i] = (int)(Math.random() * (lent1*2) + 1);  }

The following generates random integers between 1 and lent2*2 to array 2

 for(int i =0;i<lent2;i++){

     array2[i] = (int)(Math.random() * (lent2*2) + 1);  }

This prints the header Array 1

 System.out.print("Array 1: ");

The following iteration prints the content of the first array

for(int i =0;i<lent1;i++){

     System.out.print(array1[i]+" ");

 }

This prints the header Array 2

 System.out.println("Array 2: ");

The following iteration prints the content of the second array

 for(int i =0;i<lent2;i++){

     System.out.print(array2[i]+" ");

 }
