class Node(object):
def __init__(self, val):
self.val = val
self.next = None
self.prev = None
def is_palindrome(node):
# Fill this in.
node = Node('a')
node.next = Node('b')
node.next.prev = node
node.next.next = Node('b')
node.next.next.prev = node.next
node.next.next.next = Node('a')
node.next.next.next.prev = node.next.next
print is_palindrome(node)
# True
