ENIAC: Electronic Numerical Integrator and Computer.

ABACUS: Abundant Beads, Addition and Calculation Utility System.

EDVAC: Electronic Discrete Variable Automatic Computer

EDSAC: Electronic Delay Storage Automatic Computer

full meaning of ENDVAC

Answers

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:

Here is the full meaning

Implement the function permutations() that takes a list lst as input and returns a list of all permutations of lst (so the returned value is a list of lists). Do this recursively as follows: If the input list lst is of size 1 or 0, just return a list containing list lst. Otherwise, make a recursive call on the sublist l[1:] to obtain the list of all permutations of all elements of lst except the first element l[0]. Then, for each such permutation (i.e., list) perm, generate permutations of lst by inserting lst[0] into all possible positions of perm.

>>> permutations([1, 2])

[[1, 2], [2, 1]]

>>> permutations([1, 2, 3])

[[1, 2, 3], [2, 1, 3], [2, 3, 1], [1, 3, 2], [3, 1, 2], [3, 2, 1]]

>>> permutations([1, 2, 3, 4])

[[1, 2, 3, 4], [2, 1, 3, 4], [2, 3, 1, 4], [2, 3, 4, 1],

[1, 3, 2, 4], [3, 1, 2, 4], [3, 2, 1, 4], [3, 2, 4, 1],

[1, 3, 4, 2], [3, 1, 4, 2], [3, 4, 1, 2], [3, 4, 2, 1],

[1, 2, 4, 3], [2, 1, 4, 3], [2, 4, 1, 3], [2, 4, 3, 1],

[1, 4, 2, 3], [4, 1, 2, 3], [4, 2, 1, 3], [4, 2, 3, 1],

[1, 4, 3, 2], [4, 1, 3, 2], [4, 3, 1, 2], [4, 3, 2, 1]]

Answers

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.

What is Polymorphism in java programing?​

Answers

Answer:

Polymorphism means "many forms".

Explanation:

Polymorphism means "many forms", and it occurs when we have many classes that are related to each other by inheritance. Like we specified in the previous chapter; Inheritance lets us inherit attributes and methods from another class. Polymorphism uses those methods to perform different tasks.

Write code to take two words from the user. The program should convert these to lower case, then compare them: printing a positive number if string1 appears after string2 alphabetically, a negative number if string1 appears before string2 alphabetically and zero if the two strings are identical. Make sure your program does not produce any additional numerical output other than this number or it may not be graded correctly.

Answers

Answer:

Use compareTo.

Explanation:

import java.util.Scanner;

public class U2_L3_Activity_Three{

 public static void main(String[] args){

   Scanner scan = new Scanner(System.in);

   System.out.println("Enter first word: ");

   String word1 = scan.nextLine();

   System.out.println("Enter second word: ");

   String word2 = scan.nextLine();

//I had to make the string all lowercase or all uppercase for when I did this

   word1 = word1.toLowerCase();

   word2 = word2.toLowerCase();

   System.out.println("Result: " + word1.compareTo(word2));

 }

}

Following are the program to converting string value into lowercase and compare with an input string value.

Program Explanation:

Import package.Defining a class Dat.Inside the class defining the main method, and in the method, two string variable "string1, string2" is declared.After input, the value a "toLowerCase" method is used that converts string value into lower case.  After converting value into the lower case a "compareTo" method is used that compares value and prints its value.

Program:

import java.util.*;//import package for input  

public class Dat //defining a Dat

{

public static void main(String[] ax)//main method

{

String string1 ,string2; //defining String variable

Scanner sc = new Scanner(System.in);//creating Scanner class object to input value

System.out.println("Enter values: ");//print message

string1= sc.next();//input value

string2= sc.next();//input value

string1= string1.toLowerCase();//convert string value into LowerCase  

string2 = string2.toLowerCase();//convert string value into LowerCase

System.out.println("Result: " + string1.compareTo(string2));//using compareTo method

}

}

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.

What author’s worried tone indicate about rain?

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.

Explanation:

Hello! So I have been practising some coding, however, there seems to be an error in my code. I have been trying to figure out what is wrong, however, I just can't seem to find it. There is no syntax error but, there seems to be a problem with my input. I am currently using repl.it and I am making a calculator. I would input something like "multiply" however, the calculator would only square. I have tried changing the variables but it just keeps coming back to the first "if" statement. I would appreciate some help.

Answers

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.

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):

The return statement in Java is:

return ('”‘ (~[“] | ” [”e‘])*);

Write a print statement that uses an f-string to output $5,242.83

Answers

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))

In Linux, users are internally represented using a unique number called user ID or uid.

a. True
b. False

Answers

Answer:

a. True

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.

Q3: Create a class called Employee that includes three instance variables—a first name (typeString), a last name (type String) and a monthly salary (double). Provide a constructor that initializesthe three instance variables. Provide a set and a get method for each instance variable. If the monthly salary is not positive, do not set its value. {Do not write a full program, only a class}

Answers

Answer:

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

}

void setfirst_name (String f_name)//defining set method to store first_name

{

first_name = f_name; //holding the value of first_name

}  

public String getfirst_name ()//defining get method to return first_name

{

return first_name;//return first_name

}  

public void setlast_name (String l_name)//defining set method to store last_name

{

last_name = l_name; // holding the value of the last_name

}

public String getlast_name ()//defining get method to return last_name

{

return last_name;//return last_name

}  

public void setmonthly_salary(double m_salary)//defining set method to store monthly_salary

{

monthly_salary = m_salary; // holding the value of the monthly_salary

}

public double getmonthly_salary ()//defining get method to return monthly_salary

{

return monthly_salary;//return monthly_salary  

}

}

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.  

   

You are asked to write a program that prompts the user for the size of two integer arrays, user input for the size must not exceed 50, you must validate this. We will use these arrays to represent our sets. These arrays will be randomly populated in the range that is 1 through double the size of the array. So if the array is of size 20, you will randomly populate it with values in the range 1-40 inclusive.

Answers

Answer:

In Java:

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]+" ");

 }
