Merge the linked lists into a single sorted linked list and return it.
Here's your starting point:
class Node(object):
def __init__(self, val, next=None):
self.val = val
self.next = next
def __str__(self):
c = self
answer = ""
while c:
answer += str(c.val) if c.val else ""
c = c.next
return answer
def merge(lists):
# Fill this in.
a = Node(1, Node(3, Node(5)))
b = Node(2, Node(4, Node(6)))
print merge([a, b])
# 123456
