如何将链表作为函数参数发送

# 定义链表节点
class ListNode:
    def __init__(self, val=0, next=None):
        self.val = val
        self.next = next

# 创建链表
def createLinkedList(nums):
    head = ListNode()
    curr = head
    for num in nums:
        curr.next = ListNode(num)
        curr = curr.next
    return head.next

# 遍历链表
def traverseLinkedList(head):
    curr = head
    while curr:
        print(curr.val)
        curr = curr.next

# 在链表尾部插入节点
def insertNodeAtTail(head, val):
    curr = head
    while curr.next:
        curr = curr.next
    curr.next = ListNode(val)

# 将链表作为参数发送的函数
def processLinkedList(head):
    # 在这里进行链表操作，可以根据具体需求进行修改
    traverseLinkedList(head)

# 示例用法
nums = [1, 2, 3, 4, 5]
linked_list = createLinkedList(nums)
insertNodeAtTail(linked_list, 6)
processLinkedList(linked_list)
