next return list ## 合并两个有序链表,迭代法 ## 没考虑空链表的情况 class Solution: def mergeTwoLists(self, head1, head2): ## head1 和 head2 头结点指代两个链表 pre = ListNode(0) ## 额外定义个哑变量作为开头结点 head = pre while head1 and head2: ##
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. » Solve this problem [Thoughts] 简单的实现,也没什么可说的。 [Code] 1:ListNode*mergeTwoLists(ListNode*l1,ListNode*l2){ 2:if(l1==NULL)retur...
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 Solution 1: varmergeTwoLists =function(l1, l2) {if(!l1 && !l2) ...
You are given the heads of two sorted linked lists list1 and list2. Merge the two lists in a one sorted list. The list should be made by splicing together the nodes of the first two lists. Return the head of the merged linked list. Example 1: Input: list1 = [1,2,4], list2 =...
