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. 没事来做做题,该题目是说两个排序好的链表组合起来,依然是排序好的,即链表的值从小到大。 代码: 于是乎,新建一个链表
listnode2.head)#非递归4#newlist_head = s.mergeTwoListsRecursion(listnode1.head, listnode2.head) # 递归5newlist =ListNode_handle(newlist_head) # 递归或者非递归返回的都是表头,所以可以直接用第一个结点来实例化类ListNode_handle

之后同上。。 最后,当j == null时,把i及i之后的节点链表直接加入到返回链表中即可。 Python代码: # Definition for singly-linked list. class ListNode(object): def __init__(self, x): self.val = x self.next = None class Solution(object): def mergeTwoLists(self, l1, l2): """ :type l1...
简单来说就是不停的对半划分,比如k个链表先划分为合并两个k/2个链表的任务,再不停的往下划分,直到划分成只有一个或两个链表的任务,开始合并。举个例子来说比如合并6个链表,那么按照分治法,我们首先分别合并1和4,2和5,3和6。这样下一次只需合并3个链表,我们再合并1和3,最后和2合并就可以了。
Merge Two Sorted List Constarints: The number of nodes in both lists is in the range [0, 50]. -100 <= Node.val <= 100 Both l1 and l2 are sorted in non-decreasing order. 1. 2. 3. 4. Code class Solution { public ListNode mergeTwoLists(ListNode l1, ListNode l2) {...
foreach (int item_odd in y) { my_list.Add(item_odd); } my_list.Sort(); A = my_list; } as you can see its the same procedure. Put the two lists together, sort and output. Hope this helps, R. You problem is a pretty basic Python problem: ...
