改进mergeTwoLists方法,以在开始时检查空链表。 class ListNode: def __init__(self, x): self.val = x self.next = None # 改进后的将给出的数组转换为链表的函数 def linkedlist(list): if not list: # 检查列表是否为空 return None # 空列表返回None head
Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. Example: Input:1->2->4, 1->3->4Output:1->1->2->3->4->4 因为没有空间要求,所以想到ListNode*head = new ListNode(INT_MIN);重新定义一...

Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. 题目:合并两个单链表 思路:先比较两个各链表第一个节点,大的那个节点先设为合并的链表第一个节点,这样就找到了要合成的链表的节点了。
LeetCode-Merge Two Sorted Lists Description: Merge two sorted linked lists and return it as a new list. The new list should be made by splicing together the nodes of the first two lists. Example: Input: 1->2->4, 1->3->4 Output: 1->1->2->3->4->4...

解题思路: 最容易想到的思路,边遍历边比较大小,将较小的值依次放到新建的结果链表中 # Definition for singly-linked list.# class ListNode:# def __init__(self, x):# self.val = x# self.next = NoneclassSolution:defmergeTwoLists(self,l1:ListNode,l2:ListNode)->ListNode:ifl1==None:returnl2ifl2...
