最初のソリューション
# -*- coding:utf-8 -*-
# class ListNode:
# def __init__(self, x):
# self.val = x
# self.next = None
class Solution:
# 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
answer = []
head = listNode
while head:
answer.append(head.val)
head = head.next
return answer[::-1]
