Two-dimensional random walk (20 points). A two-dimensional random walk simulates the behavior of a particle moving in a grid of

points. At each step, the random walker moves north, south, east, or west with probability equal to 1/4, independent of previous moves. Write a program RandomWalker.java that takes an int command-line argument n and simulates the motion of a random walk for n steps. Print the location at each step (including the starting point), treating the starting point as the origin (0, 0). Also, print the square of the final squared Euclidean distance from the origin as double. Note: you do not need arrays for this problem, just keep track of the x and y coordinates during the random walk.

Answer:

The following code in the explanation does the job for you. Here I have made use of Random class of Java to generate random numbers.

Explanation:

Code:

import java.util.*;

class RandomWalker {

  public static void main(String args[]){

      int n = Integer.parseInt(args[0]);

      int x = 0;

      int y = 0;

      Random random = new Random();

      for(int i = 0; i < n; i++){

          int tmp = random.nextInt(4);

          if(tmp == 0){

              x++;

          }

          if(tmp == 1){

              y++;

          }

          if(tmp == 2){

              y--;

          }

          if(tmp == 3){

              x--;

          }

          System.out.println("(" + x + "," + y + ")");

      }

      int distance = x*x + y*y;

      System.out.println("Squared Distance = " + distance);

  }

}

Write a class named Taxicab that has three **private** data members: one that holds the current x-coordinate, one that holds the
Licemer1 [7]

Answer:

See explaination

Explanation:

class Taxicab():

def __init__(self, x, y):

self.x_coordinate = x

self.y_coordinate = y

self.odometer = 0

def get_x_coord(self):

return self.x_coordinate

def get_y_coord(self):

return self.y_coordinate

def get_odometer(self):

return self.odometer

def move_x(self, distance):

self.x_coordinate += distance

# add the absolute distance to odometer

self.odometer += abs(distance)

def move_y(self, distance):

self.y_coordinate += distance

# add the absolute distance to odometer

self.odometer += abs(distance)

cab = Taxicab(5,-8)

cab.move_x(3)

cab.move_y(-4)

cab.move_x(-1)

print(cab.odometer) # will print 8 3+4+1 = 8

Regarding the excerpt, what synthesized information helps spread a message to a large audience? Check all that apply

1. taking advantage of technology

2. being good at public speaking

3. appearing on a television program

4. speaking mostly to college students

5. presenting at professional conferences

Answer:

The correct options are 1, 2, 3 and 5

Explanation:

In order to convey the message to a large audience, an individual can adopt certain measures that can ensure efficient spread of message.

Jaylen used technology (Skype) to chat with students nationwide, therefore, option 1 is correct.

Speaking in front of more than a thousand educators at the Florida Teacher Conference clearly suggests that Jaylen is good at public speaking, therefore, option 2 is correct.

Jaylen appeared on numerous TV networks as well as she presented at professional conferences which helps in spreading the message across a large audience, therefore, option 3 and 5 are also correct.

It is not necessary to speak to only college students, she can speak to students of all education levels to spread her message to large audience, therefore, option 4 is not correct.
