4.20 LAB: Vampire Party Introduction This lab is related to one of your choices for the final project which is about 2d list manipulation. This lab will let you practice with large- scale coding projects that typically contain many functions. Lab Description Consider a city, represented by a 2D list. Each cell contains either 1 or 0 that represents either a vampire or a human. At night, vampires will infect adjacent humans (located up/down/left/right). You want to know what the city will look like after one night. To do that you will implement two functions vampirize() and next day(). Important Notes: • A city is a 2D list of integers that represents the city. A human is represented with 0 A vampire is represented with 1 • The 2D list must have a height and width of at least 1. • The city (2D list) can be different sizes so don't hard code the shape. Instead, use len () to get the number of rows or columns. • Assume that the 2D list represents a matrix- that is, every row has the same number of columns but the number of rows and columns could be different. So, the matrix looks like a rectangle, not necessarily a square A vampire infected that night is not yet contagious. This means that infected humans cannot infect adjacent humans until the next night • You may import the copy module to do a deep copy of a 2d list. No other imports are allowed.

Create a Point classCreate a Point class as we did in the class. We'll use this to create Point objects that hold x,y coordinates of locations where we'll want to draw. Draw DotsWrite a drawDots(points) function that takes a list points as input and draws a dot on the drawing window for each Point. For example, you should be able to call your function as follows: >>> p = Point(10, 20) >>> q = Point(20, 30) >>> points = [p, q] >>> drawDots(points)

11. Given the following list, trace the given code and draw the list afterward. SHOW YOUR WORK. head "chair" "table" "door" "sofa" "wall" "window" "floor" LLNode Ruli int temp; head; head.getLink (); while (q != null) { RitetInfo () ; RisetInfo (g.getInfo()); AetInfo (temp); LgetLink (); Aetlink (RgetLink()); a = temp = d AigetLink () ; if (p != null) RigetLink (); g = }

For any element in keysList with a value greater than 50, print the corresponding value in itemsList, followed by a comma (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20,30, 1 #include 2 3 int main(void) { const int SIZE_LIST = 4; int keysList[SIZE_LIST]; int itemsList[SIZE_LIST]; int i; 4 6 7 8 scanf("%d", &keysList[0]); scanf ("%d", &keysList[1]); scanf("%d", &keysList[2]); scanf("%d", &keysList[3]); 10 11 12 13 scanf ("%d", &itemsList[0]); scanf ("%d", &itemsList[1]); scanf("%d", &itemsList[2]); scanf ("%d", &itemsList[3]); 14 15 16 17 18 19 /* Your code goes here */ 20 21 printf("\n"); 22 23 return 0; 24 }

• Do not add statements that call print, input , or open , or add an import statement. • Do not use any break or continue statements. We are imposing this restriction (and we have not even taught you these statements) because they are very easy to abuse, resulting in terrible, hard to read code. • Do not modify or add to the import statements provided in the starter code. import math from typing import List, TextIO # For simplicity, we'll use "Station" in our type contracts to indicate that # we mean a list containing station data. # You can read "Station" in a type contract as: List[int, str, float, float, int, int, int] 23 # where the values at each index represent the station data as described in the # handout on Quercus. # A set of constants, each representing a list index for station information. ID - 0 NAME - 1 LATITUDE - 2 LONGITUDE - 3 CAPACITY - 4 BIKES_AVAILABLE - 5 DOCKS_AVAILABLE - 6 NO_KIOSK - 'SMART" # For use in the get_lat_lon_distance helper function EARTH RADIUS -…

Data structure & Algrothium java program Create the three following classes: 1. class containing two strings attributes first name and last name.2. class containing the name object and an ArrayList of string to store the list gifts. This class would extend the attached NicePersonInterface.java3. class containing one ArrayList of Names to store the naughty names. Another ArrayList of NicePerson to store the nice names and gifts. Add atleast 4 names in each list and display all information.

Redesign LaptopList class from previous project public class LaptopList {       private class LaptopNode  //inner class     {         public String brand;         public double price;         public LaptopNode next;           public LaptopNode(String brand, double price)         {                // add your code         }         public String toString()         {             // add your code         }     }       private LaptopNode head; // head of the linked list       public LaptopList(String fname) throws IOException     {         File file = new File(fname);         Scanner scan = new Scanner(file);         head = null;         while(scan.hasNextLine())         {             // scan data             // create LaptopNode             // call addToHead and addToTail alternatively          }     }       private void addToHead(LaptopNode node)     {             // add your code     }       private void addToTail(LaptopNode node)     {             // add your code     }       private…

PYTHON LAB: Inserting an integer in descending order (doubly-linked list) Given main.py and an IntNode class, complete the IntList class (a linked list of IntNodes) by writing the insert_in_descending_order() method to insert new IntNodes into the IntList in descending order. Ex. If the input is: 3 4 2 5 1 6 7 9 8 the output is: 9 8 7 6 5 4 3 2 1   _____________________________________________________________________________________   Main.py: from IntNode import IntNode from IntList import IntList   if __name__ == "__main__":     int_list = IntList()         input_line = input()     input_strings = input_line.split(' ')         for num_string in input_strings:         # Convert from string to integer         num = int(num_string)           # Insert into linked list in descending order         new_node = IntNode(num)         int_list.insert_in_descending_order(new_node)             int_list.print_int_list() IntNode.py class IntNode:     def __init__(self, initial_data, next = None,…

Main difference between an array and an ArrayList is that an ArrayList can store more data types an ArrayList can store more elements an ArrayList executes faster for retrieval and insertion an ArrayList takes care of the memory management automatically an ArrayList uses positions and an array uses indices

Make a class named ClassList that stores an arraylist of strings and create an add method that adds Strings to the arraylist
