Write a Java program to merge the two sorted linked lists. Sample Solution: Java Code: importjava.util.*publicclassSolution{publicstaticvoidmain(String[]args){// Create two sorted linked listsListNodelist1=newListNode(1);list1.next=newListNode(3);list1.next.next=newListNode(7);list1.next.n...
class Solution { public ListNode mergeTwoLists(ListNode l1, ListNode l2) { if (l1 == null){ return l2; } else if (l2 == null){ return l1; } else if (l1.val < l2.val){ l1.next = mergeTwoLists(l1.next, l2); return l1; } else{ l2.next = mergeTwoLists(l1, l2.next); ...
Using the main() method, we demonstrate the use of mergeLists() by passing two lists of integers (numbers1 and numbers2) and two lists of strings (words1 and words2). We merge the elements of each pair of lists and print the merged lists.Flowchart:For more Practice: Solve these Relate...
public ListNode mergeTwoLists(ListNode list1, ListNode list2) { if (list1 == null) return list2; if (list2 == null) return list1; if (list1.val <= list2.val) { list1.next = mergeTwoLists(list1.next,list2); return list1; } else { list2.next = mergeTwoLists(list1,list2....
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&& ...
题目描述: 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. 解题思路: 题目的意思是将两个有序链表合成一个有序链表。 逐个比较加入到新的链表即可。
public ListNode mergeTwoLists(ListNode l1, ListNode l2) { // 创建一个dummy头,从后面开始接 ListNode dummy = new ListNode(0); ListNode curr = dummy; // 依次比较拼接 while(l1 != null && l2 != null){ if(l1.val <= l2.val){
应该通过将前两个列表的节点拼接在一起来创建新列表。 Java解决方案 解决问题的关键是定义一个假冒的头部。然后比较每个列表中的前几个元素。将较小的一个添加到合并列表中。最后,当其中一个为空时,只需将其追加到合并列表中即可,因为它已经排序。 public ListNode mergeTwoLists(ListNode l1, ListNode l2) { ...
Leetcode第21题 Merge Two Sort Lists 【题目】将两个升序链表合并为一个新的升序链表并返回。新链表是通过拼接给定的两个链表的所有节点组成的。 示例: 输入:1->2->4, 1->3->4 输出:1->1->2->3->4->4 【解法一】 //迭代法 class Solution { public ListNode mergeTwoLists(ListNode l1, ListNo...
In these examples, we combined the lists, but in the final list, we had duplicate elements. This may not be the desired output in many cases. Next, we will learn to merge the lists, excluding duplicates. 2. Merging Two ArrayLists excluding Duplicate Elements ...
