Describe in pseudo-code an implementation of the methods addLast(e) and addBefore(p,e) realized by using only methods in the set: {isEmpty() - a boolean function that checks if the list is empty, checkPosition (p) - a procedurre that checks / get the position specified by the pointer p. first() - a function that gets and returns the first position of the list, last() - a function that gets and returns the last position of the list, prev(p) - a function that gets and returns a pointers to the previous nodes of the current pointer p. addAfter (p, e) - a procedure that adds the element e to the position specified by a pointer p, addFirst(e) - a procedure that adds the element e to the first position of the list }.

Java Design and draw a method called check() to check if characters in a linked list is a palindrome or not e.g "mom" or "radar" or "racecar. spaces are ignored, we can call the spaces the “separator”. The method should receive the separator as a variable which should be equal to “null” when no separator is used.
In python. Write a LinkedList class that has recursive implementations of the add and remove methods. It should also have recursive implementations of the contains, insert, and reverse methods. The reverse method should not change the data value each node holds - it must rearrange the order of the nodes in the linked list (by changing the next value each node holds). It should have a recursive method named to_plain_list that takes no parameters (unless they have default arguments) and returns a regular Python list that has the same values (from the data attribute of the Node objects), in the same order, as the current state of the linked list. The head data member of the LinkedList class must be private and have a get method defined (named get_head). It should return the first Node in the list (not the value inside it). As in the iterative LinkedList in the exploration, the data members of the Node class don't have to be private. The reason for that is because Node is a trivial class…
Considering a singly linked list of integers implementation, assuming that elements of the list are always in ascending order, write a function (find_median) that finds and returns median value. The function cannot scan the list more than ONCE. class SinglyList: class _Node: def __init__(self, e, next): self._element = e self._next = next def __init__(self): self._head = self._tail = None def find_median(self):
The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
Implements clone which duplicates a list. Pay attention, because if there are sublists, they must be duplicated as well. Understand the implementation of the following function, which recursively displays the ids of each node in a list Develop your solution as follows: First copy the nodes of the current list (self) Create a new list with the copied nodes Loop through the nodes of the new list checking the value field If this field is also a list (use isinstance as in the show_ids function) then it calls clone on that list and substitutes the value. Complete the code: def L4(*args,**kwargs): class L4_class(L): def clone(self): def clone_node(node): return <... YOUR CODE HERE ...> r = <... YOUR CODE HERE...> return r return L4_class(*args,**kwargs)
Implement a member method for the List ADT called removeDuplicates(). The method removes every duplicate from the list such that there is only ONE copy of each element in the list. The method also returns the number of copies it removed. For example, if L = {Joe, Bob, Joe, Ned, Bob, Ron, Ron}, a call to L.removeDuplicates modifies the list such that L = {Joe, Bob, Ned, Ron} and returns 3. import java.util.Iterator;import java.util.NoSuchElementException; public class Mock1ListWrapper { public static interface List<E> extends Iterable<E> { public int size(); public boolean isEmpty(); public boolean isMember(E e); public int firstIndexOf(E e); public int lastIndexOf(E e); public void add(E e); public void add(E e, int position); public E get(int position); public E remove(int position); public E replace(int position, E newElement); public void clear(); public Object[] toArray(); public int removeDuplicates(); } @SuppressWarnings("unchecked") public static…
The for construction is a loops that iteratively processes a given list. Consequently, it works so long even though there are objects to process. What about this claim: true or false?
1. Consider an ADT list of integers. Write a method that computes the maximum of the integers in the list aList. The definition of your method should be indepen- dent of the list's implementation.
Implement a circular singly linked list in C programming language. Create functions for the ff: 1. Transversal 2. Insertion of element (at the beginning, in between nodes, and at the end) 3. Deletion of element 4. Search 5. Sort
1. Implement a List using array: a. Implement ArrayList<T> class of ListADT<T> interface which will define the following methods (i) public T removeLast(); //Removes and returns the last element in the list. (ii) public T removeFirst(); //Removes and returns the first element in the list. (iii) public T remove(T element); //Removes and returns the specified element. (iv) public boolean contains(T target); //Return True if the list contains the target element otherwise False. (v) public String toString(); // Returns a string representation of the list. b. Implement ArrayUnorderedList<T> class which will extends ArrayList<T> by defining the following additional methods (i) public void addToFront(T element); //Adds the specified element to the front of the list. (ii) public void addToRear(T element); //Adds the specified element to the rear of the list. (iii) public void addAfter(T element, T target); //Adds the specified element after the specified target element.…
Given a singly linked list, print reverse of it using a recursive function printLinkedList( node *first ) where first is the pointer pointing to the first data node. For example, if the given linked list is 1->2->3->4, then output should be: 4 3 2 1 (note the whitespace in between each data value)
