In python, how do you move the pointer of a doubly linked list to the last node? Also in python, how do you move the current pointer "n" elements ahead (circularly)

def go_last(self):
# moves 'current' pointer to the last node

def skip(self,n:int):
# moves 'current' pointer n elements ahead (circularly)

Write a Matlab script which creates two vectors from the table below; pne vector for the element names and a second for element atomic numbers. Print the statement "[element name] has an odd atomic number: [element atomic number]." for each element with an odd atomic number.

• Use a for loop.
• Use a if statement.
• Print one statement per line.
• Use the mod function when testing for odd atomic numbers.

In C# please

Exercise #4:

Create a two (2) instances of the “Dog” class in your “Main” method. One will be created using the default constructor and the other should be made using the overloaded constructor. That means that you should pass the overloaded constructor arguments that come from user input.

Print out each of the dog’s three attributes using the accessors. Then call the “UpdateBark” method for both and print out their fields again, but this time through the “ToString” method.

Example (blue is default dog’s attributes, green is the user’s dog’s):

Creating a default dog…

Finished creating a default dog!

Default dog bark sound is Yelp!

Default dog size is 20 inches.

Default dog’s cuteness is cute dog.

Continued on third page…

Please enter the sound of your dog’s bark: “MOOOOOO!”

Please enter the size of your dog: “10”

Please enter the cuteness of your dog: “ugly dog.”

Your dog bark sound is MOOOOOO!

Your dog size is 10 inches.

Your dog’s cuteness is ugly dog.

Both dogs are doing a scary bark! Their cuteness has been affected!

Default dog bark sound is Yelp!

Default dog size is 20 inches.

Default dog’s cuteness is average.

Your dog bark sound is MOOOOOO!

Your dog size is 10 inches.

Your dog’s cuteness is average.

You mission is create a C# program with the following. 1. At the top center of the page is a title which displays your name - use a label. a. adjust the font size from the default to a bigger size. b. adjust the font color to a different color than the default c. name the label using a naming convention shown in the chapter. Use this same format for all of your objects. 2. Below the title, centered, place a picture of yourself using the picturebox tool explained in the chapter. a. name the picture box with a meaningful name using the naming convention you used in #1. b. size the picture to fit evenly under your title. c. make sure the picture is properly saved in the right location within the C# application or it won't be copied when you submit the assignment. Do not code a complete location like c:/myfiles .... I won't have the same folders as you. It has to reside in the proper images folder which is located with your other program files. 3. Create TWO buttons on the same line (row) as each other. They should be evenly spaced apart from each other..Same space between the left edge, center, and right edge. a. Give each button a meaningful name using the naming convention you used for #1. b. The left button should display (within the button itself), the words - my favorite quote. c. The right button should display (within the button itself), the words - what I do for fun. 4. Double click the left button. You should now be in the code area for the click event for this button. a. Create the code (only takes one line) to display your favorite quote when the button is clicked. 5. Double click the right button. You should now be in the code area for the click event for this button. a. Create the code (only takes one line) to display a statement about what you do for fun. 6. Place another button below the two buttons, centered under the picture. a. Name the button with a meaningful name using the naming convention you used in #1. b. The words inside the button will be - close program c. Double click the button to enter code under the button. d. Enter a line of code which will display something funny about the person leaving your program. e. Enter a second line of code which closes the program. Test, Test, Test! Make sure it works. I will be testing your program!

Q: Assistance in understanding and solving this example from Data Structure & Algorithms (Computer Science) with the steps of the solution to better understand, thanks.

##Using R studio language and code to use provided below, thanks.

In this assignment, we will implement a function to evaluate an arithmetic expression. You will use two stacks to keep track of things. The function is named ‘evaluate’, it takes a string as input parameter, and returns an integer. The input string represents an arithmetic expression, with each character in the string being a token, while the returned value should be the value of the expression.

Examples:

• evaluate ('1+2*3') ➔ 7

• evaluate ('1*2+3') ➔ 5

##This is the code provided to use

Python's list."""

please good answer

two techniques for implementing a top-down parser: a recursive descent parser and a table-driven parser.

a.What are the advantages of writing a recursive descent parser instead of a table-driven parser?

b.What are the disadvantages of recursive descent?

please provide the reason why you are choosing an option to be right. its for my understanding . and also why other options are not right

expecting an early response.will rate your answer. thankyou

Car class Question

Design a class named car that has the following fields: YearModel: The yearModel field is an integer that holds the car's year model. Make: The make field references a string that holds the make of the car. Speed: The speed field is an integer that holds the car's current speed. In addition, the class should have the following constructor and other methods: Constructor: The constructor should accept the. car's year model and make as arguments. The values should be assigned to the object's yearModel and make fields. The constructor should also assign 0 to the speed field. Accessors: Design appropriate accessor methods to get the values stored in an object's yearModel, make, and speed fields. Accelerate: The accelerate method should add 5 to the speed field each time it is called. Brake: The brake method should subtract 5 from the speed field each time it is called. Next, design a program that creates a car object, and then cals the accelerate method fibe times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method 5 times. After each call to the brake method, get the current speed of the car and display it..........

Thanks for the help guys pseudocode and flowchart please

c++

1. write a c++ function that received two doubles that represent the sides of a triangle and an integer that represents the number of triangles of that size. calculate the area of all these triangles. remember area of a triangle is ahalf base times width. and return this value as a double.

Write a Java program to convert octal (integer) numbers into their decimal number equivalents (exactly the opposite of what you have done in Assignment 4). Make sure that you create a new Project and Java class file for this assignment. Your file should be named “Main.java”. You can read about octal-to-decimal number conversions on wikepedia

Assignment 4 is at the bottom

Objective

Your program should prompt the user to enter a number of no greater than 8 digits. If the user enters a number greater than 8 digits or a value less than 0, it should re-prompt the user to enter a number again*. You do not need to check if the digits are valid octal numbers (0-7), as this is guaranteed.

Instructions

• Note that the conversion logic should be in a separate method (not the main() method).
• main() method will take the input from the user and pass it to the conversion() method.
• The conversion() method will convert the input octal to decimal and print the output.
  • No return value is required.
  • a sample structure is shown below.

• Use a sentinel while loop to solve the problem.
• Ideally, you should copy your assignment 4 code here and modify it to serve the new purpose. This will save you time.

• USE ONLY INTEGER VARIABLES FOR INPUTS AND OUTPUTS.
• USE ONLY THE TECHNIQUES TAUGHT IN CLASS

main(){

int oct = user input;

conversion(oct);

}

void conversion(int o){

// logic goes here.

print(decimal);

}

Goals

• more experience in WHILE loop.
• experience in Java Methods
• logical thinking

Sample Runs

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 77777777

16777215

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 775002

260610

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 0

0

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 55

45

Sample Program Run (user input is underlined)

Enter up to an 8-digit octal number and I will convert it for you: 777777777

Enter up to an 8-digit octal number and I will convert it for you: 777777777

Enter up to an 8-digit octal number and I will convert it for you: 700000000

Enter up to an 8-digit octal number and I will convert it for you: 77

63

Assignment 4:

// Main.java : Java program to convert decimal number to octal

import java.util.Scanner;

public class Main {

public static void main(String[] args) {

int inputNum, convertedNum;

Scanner scan = new Scanner(System.in);

// Input of integer number in decimal

System.out.print("Please enter a number between 0 and 2097151 to convert: ");

inputNum = scan.nextInt();

// validate the number

if(inputNum < 0 || inputNum > 2097151)

System.out.println("UNABLE TO CONVERT");

else

{

int weight=0; // weight of the digit, used for converting to octal

convertedNum = 0; // variable to store the number in octal

int temp = inputNum;

int digit;

// loop that continues till we convert the entire number to octal

while(temp > 0)

{

digit = (temp%8); // get the remainder when the number is divided by 8

// multiply the digit with its weight and add it to convertedNum

convertedNum += digit*Math.pow(10, weight);

temp = temp/8; // remove the last digit from the number

weight++; // increment the weight

}

// display the integer in octal

System.out.printf("Your integer number " + inputNum + " is %07d in octal",convertedNum);

}

scan.close();

}
