## LeetCode 21 合并链表 ## 引用官方代码,定义结点类 class ListNode: def __init__(self, x): self.val = x self.next = None 将数组转换为链表,也可以理解为链表的创建(官网不给出): ## 将给出的数组,转换为链表 def linkedlist(list): head = ListNode(list[0]) ## 列表的第一个元素。这里...

list1 和 list2 均为非降序链表 样例 思路:模拟 由于两个链表已经是升序的,所以可以按题意直接模拟处理。 当list1 和 list2 均还有结点时,取它们中较小的头结点放入结果链表中,然后不断循环。 最后当其中一个链表为空时,将另一个链表剩余的部分全部插入结果链表尾部即可。 进阶: LeetCode 23: 合并 k 个...
