Expected Behavior Write a Python method sort) to sort a LinkedList object in descending.order of the attribute_value. The code for the LinkedList class is shown below. You should use the sorting algorithm described here Given a LinkedList object 11ist, the execution of the code 11ist.sort() print (1list) should cause the sorted list to be printed out. The code for the LinkedList class is as follows: class Node: def init (self, value): self. value value selfnext None - # getter for the value attribute def value(selE) return self.value # getter for the-next attribute def next ( self ) return self. next return str (self. _value) -init-(self): def str (self): + ":" class LinkedList def self. head None # add a node to the head of the list def add(self, node): node. nextself. head self. head node # remove a node from the head of the list and return the node def remove(self) assert self. headNone node self. head self. headode. next node. _next None return node
