The JavaSetsallow only unique elements. When we push both lists in aSetand theSetwill represent a list of all unique elements combined. In our example, we are usingLinkedHashSetbecause it will preserve the element’sorder as well. ArrayList<String>listOne=newArrayList<>(Arrays.asList("a","...
The method creates a newly created mergedList from an ArrayList. It iterates up to the maximum length of the two lists using a for loop. In each iteration, it checks if the index is within the bounds of each list. It adds the corresponding element to the mergedList using the add() me...
不多说,直接上代码了 1publicListNode mergeTwoLists(ListNode l1, ListNode l2) {2ListNode dummyHead =newListNode(-1);3ListNode node =dummyHead;4while(l1 !=null&& l2 !=null) {5if(l1.val <=l2.val) {6node.next =l1;7l1 =l1.next;8}else{9node.next =l2;10l2 =l2.next;11}12node =...
分析:合并两个有序序列,这个归并排序中的一个关键步骤。这里是要合并两个有序的单链表。由于链表的特殊性,在合并时只需要常量的空间复杂度。 编码: publicListNode mergeTwoLists(ListNode l1, ListNode l2) {if(l1 ==null&& l2 ==null)returnnull;if(l1 ==null&& l2 !=null)returnl2;if(l2 ==null&& l...
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 1. 2. 3.
Merge Two Sorted Lists·合并两个有序链表 秦她的菜 吉利 程序员题目描述 英文版描述 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 ...
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. 题目要求我们将两个有序链表合成一个有序的链表。 Example: 输入: 1->2->4, 1->3->4 ...
Sort a linked list in O(n log n) time using constant space complexity. 1.解题思路 题目要求时间复杂度为O(n log n),所以我们就想到用归并排序,自然就想到和上一题的mergeTwoLists。 但要做mergeTwoLists,必须得先将当前的list分割成两个List,所以采用递归实现。
