# 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
# @return int整型一维数组

class Solution:
    def listnodeToVector(self, head: ListNode) -> List[int]:
        # write code here
        r = []
        while head:
            r.append(head.val)
            head = head.next
