We need a linked list to hold information about penguins in a zoo. You will need the following integers for your IntNode (see below). I have included sample values for one of the penguins: penguin ID: 45821 penguin weight (kg): 11 penguin height (cm): 90 We now need to track the number of penguins in the zoo. I would like to propose a better way to track the size of the list. Rather than traversing the list every time you need to know its size, why not keep a variable called listSize that increments every time you add a node to the list and decrements anytime you remove an item from the list? public class penguinList { //nested class IntNode goes here private IntNode first; private int listSize; //...the methods of penguinList class go here } Now, you just need to increment the listSize instance variable in every method that adds a node to the list. If you have any methods that removes a node from the list, decrement the listSize instance variable in those methods instead.…

Without using the java collections interface (i.e. do not import java.util.List, LinkedList, etc. ) Write a java program that inserts a new String element (String newItem) into a linked list before another specified item (String itemToInsertBefore). For example if items "A", "B", "C" and "D" are in a linked list in that order and the below method is called, insertBefore("E", "C"), then "E" would be inserted before "C", making the final list to be "A", "B", "E", "C" and "D" with no nulls or blank elements or any elements missing or anything. It should work for all lenghths of linkedlists of Strings. public Boolean insertBefore(String newItem, String itemToInsertBefore) { // returns true if done successfully, else returns false if itemToInsertBefore cannot be found or some other error }
Given the source code of linked List, answer the below questions(image): A. Fill out the method printList that print all the values of the linkedList: Draw the linked list. public void printList() { } // End of print method B. Write the lines to insert 10 at the end of the linked list. You must draw the final linked List. Notice that you can’t use second or third nodes. Feel free to define a new node. Assume you have only a head node C. Write the lines to delete node 2. You must draw the final linked list. Notice that you can’t use second or third node. Feel free to define a new node. Assume you have only a head node
Consider a linked list (SLL or DLL your choice) in which, to delete anelement from the list, we simply mark that node for the deletion.Whenever the number of deleted nodes in the list exceeds the number ofnon-deleted nodes, we simply delete all nodes which were marked fordeletion. Implement the following operations for such a linked list.1. addFirst2. addLast3. delFirst4. delLast5. Delete (mark for deletion) an ith node in the list.6. display all non-deleted nodes in the list7. Size : number of non-deleted nodes in the list.8. Recall the last deleted node in the list.
Implement an instance method, called getFirstHalf, that belongs to yourThingLinkedBag. The method returns as output a linked list that includes allvalues in the first half of the bag's linked list. For example, for the following bag3-->5-->8-->9. the method returns 3-->5.If the bag includes an odd number of nodes, then the middle element belongs tothe first half and is included in the output.Make sure to include the methodheader. The bag should remain unchanged (i.e., do not remove the returnedvalues from the bag).
Create a new concrete class that implements MyMap using open addressing with linear probing. For simplicity, use f(key) = key % size as the hash function, where size is the hash-table size. Initially, the hash-table size is 4. The table size is doubled whenever the load factor exceeds the threshold (0.5).

Store a dictionary of a limited set of words as a hash table. Implement a spell check program that, given an input text file, will check for the spelling using the hash table-based dictionary and in the case of misspelled words will correct the same.
Your task is to: Implement the LinkedList interface ( fill out the implementation shell). Put your implementation through its paces by exercising each of the methods in the test harness. Create a client ( a class with a main ) ‘StagBusClient’ which builds a bus route by performing the following operations on your linked list: - Create (insert) 4 stations - List the stations - Check if a station is in the list (print result). Check for a station that exists, and one that doesn’t - Remove a station. List the stations - Add a station before another station. List the stations - Add a station after another station. Print the stations LinkedList.java package linkedList; public interface LinkedList { public Boolean isItemInList(String thisItem); // true if it is, false if not public Boolean addItem(String thisItem); // true if added, false if it was already there, or an error public Integer itemCount(); public void listItems(); public Boolean deleteItem(String thisItem); // true if deleted,…
Draw a diagram of the hashtable of size 23 that would result from inserting these Strings in the following order: A, W, X, Y, CM, CK, BD, H, MOB, BD. Manually compute the number of collisisons that should result. JAVA
One way to potentially reduce the complexity of computing the hash code for Strings is to compute it only once—when the String is created.Future hashCode calls would return the precomputed value. Because the value of a String never changes, this has the potential to be useful. How would you rate the efficacy of such a method?
