单链表排序的python实现

# 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 node
# @return ListNode类
#
class Solution:
    def sortInList(self , head: ListNode) -> ListNode:
        # write code here
        mylist = []
        while head:
            mylist.append(head.val)
            head = head.next
        mylist.sort()
        cur = ListNode(-1)
        dummy = cur
        for i in mylist:
            cur.next = ListNode(i)
            cur = cur.next
        return dummy.next
