题目:
输入一个链表的头节点,从尾到头反过来返回每个节点的值(用数组返回)。
示例 1:
输入:head = [1,3,2]
输出:[2,3,1]
限制:
0 <= 链表长度 <= 10000
题目的理解:
要注意的是值顺序的翻转,不是指列表。
python实现
# Definition for singly-linked list.
# class ListNode:
# def __init__(self, x):
# self.val = x
# self.next = None
class Solution:
def reversePrint(self, head: ListNode) -> List[int]:
if head is None:
return list()
current = head
numbs = list()
while current.next is not None:
numbs.append(current.val)
current = current.next
numbs.append(current.val)
numbs.reverse()
return numbs
提交
成功// END 算法题 刷的有点慢啊
