Python Code:

class Node:
def __init__(self, initial_data):
self.data = initial_data
self.next = None

def __str__(self):
return str(self.data)

class LinkedList:
def __init__(self):
self.head = None
self.tail = None

def append(self, new_node):
if self.head == None:
self.head = new_node
self.tail = new_node
else:
self.tail.next = new_node
self.tail = new_node

def Generate(self,num_nodes):
# Your code goes here

def printList(self):
# Your code goes here


def swap(self):
# Your code goes here


if __name__ == '__main__':
LL = LinkedList()
num_nodes = int(input())
LL.Generate(num_nodes)
LL.swap()
LL.printList()
