**PYTHON 3** Write a LinkedList class that has recursive implementations of the add, display, and remove methods described in the lesson. It should also have recursive implementations of the contains, insert, and reverse methods described in the exercises. You may use default arguments and/or helper functions. class Node: """ Represents a node in a linked list """ def __init__(self, data): self.data = data self.next = None class LinkedList: """ A linked list implementation of the List ADT """ def __init__(self): self.head = None def add(self, val): """ Adds a node containing val to the linked list """ if self.head is None: # If the list is empty self.head = Node(val) else: current = self.head while current.next is not None: current = current.next current.next = Node(val) def display(self): """ Prints out the values in the linked list """ current = self.head while current is not None: print(current.data, end=" ") current = current.next print() def remove(self, val): """ Removes the node containing val from the linked list """ if self.head is None: # If the list is empty return if self.head.data == val: # If the node to remove is the head self.head = self.head.next else: current = self.head while current is not None and current.data != val: previous = current current = current.next if current is not None: # If we found the value in the list previous.next = current.next def is_empty(self): """ Returns True if the linked list is empty, returns False otherwise """
