#         self.val = x
#         self.next = None

class Solution:
def __init__(self):
self.l = []
# 返回从尾部到头部的列表值序列，例如[1,2,3]
def printListFromTailToHead(self, listNode):
# write code here
if listNode == None:
return ""
if listNode.next != None:
self.printListFromTailToHead(listNode.next)
self.l.append(listNode.val)
return self.l
