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 = ListNode(list[0]) cur = head for...
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. 这道题目题意是要将两个有序的链表合并为一个有序链表。为了编程方便,在程序中引入dummy节点。具体程序如下: 1/**2* Definition for singly-linked list...
You are given the heads of two sorted linked lists list1 and list2. Merge the two lists in a onesortedlist. The list should be made by splicing together the nodes of the first two lists. Returnthe head of the mergedlinked list. Example 1: Input: list1 = [1,2,4], list2 = [1,...
Merge two sorted linked lists and return it as a new sorted list. The new list should be made by splicing(拼接) together the nodes of the first two lists. The sorted list is in ascending order. typedef struct _ListNode { int val; struct _ListNode *next;...
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. 思路: easy 。 算法: AI检测代码解析 1. public ListNode mergeTwoLists(ListNode l1, ListNode l2) { ...
Merge two sorted linked lists andreturnit as anewlist. Thenewlist 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 1. 2. 3. 4. 5. 6.
Your algorithm should run in linear time on the length of the output list. 2【题目】数据结构有序链表问题。Write a function to merge two sorted linked lists. T he input lists have their elements in sorted order, from lowest to highest. T he outputlist should also be sorted from lowest ...
LinkList——Merge Two Sorted Lists 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...
21. Merge Two Sorted Lists 题目要求: 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. 归并两个已经排序好的链表,归并好了仍然是有序链表。
