# class ListNode: # def __init__(self, x): # self.val = x # self.next = None # # 代码中的类名、方法名、参数名已经指定,请勿修改,直接返回方法规定的值即可 # # # @param listNode ListNode类 # @return int整型一维数组 # class Solution: def printListFromTailToHead(self , listNode: ListNode) -> List[int]: # write code here ret=[] if not listNode: return ret ret.append(listNode.val) while listNode.next: listNode=listNode.next ret.append(listNode.val) ret.reverse() return ret先遍历进list,再reverse翻转
