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 head ListNode类 the head
# @return bool布尔型
#
class Solution:
def isPail(self , head: ListNode) -> bool:
lst = []
cur = head
while cur:
lst.append(cur.val)
cur = cur.next
lst1 = lst[::-1]
if lst1 == lst:
return True
else:
return False
