标签:链表 lis 有序链表 sel tco python code 输出 val
将两个有序链表合并为一个新的有序链表并返回。新链表是通过拼接给定的两个链表的所有节点组成的。
示例:
输入:1->2->4, 1->3->4 输出:1->1->2->3->4->4
# Definition for singly-linked list. class ListNode: def __init__(self, x): self.val = x self.next = None class Solution: def mergeTwoLists(self, l1, l2): """ :type l1: ListNode :type l2: ListNode :rtype: ListNode """ rnode = ListNode(0) cur = rnode while l1 != None: if l2==None: cur.next = l1 return rnode.next if l1.val >= l2.val: cur.next = l2 cur = cur.next l2 = l2.next else: cur.next = l1 cur = cur.next l1 = l1.next if l2: cur.next = l2 return rnode.next
