1. Merging Two ArrayLists Retaining All Elements This approach retains all the elements from both lists, including duplicate elements. The size of the merged list will be arithmetic sum of the sizes of both lists. 1.1. UsingList.addAll() TheaddAll()method is the simplest way toappend all ...
In the above methods, we reverse the sections of the input array in-place, multiple times, to get the required result. For reversing the sections, we used the two-pointer approach where swapping of elements was done at both ends of the array section. Specifically, we first reverse all the...
Given two sorted integer arrays A and B, merge B into A as one sorted array. Note: You may assume that A has enough space (size that is greater or equal tom+n) to hold additional elements from B. The number of elements initialized in A and B aremandnrespectively. 题解: 这道题是...
Each element in the result should appear as many times as it shows in both arrays. The result can be in any order.Follow up:What if the given array is already sorted? How would you optimize your algorithm? What if nums1's size is small compared to nums2's size? Which algorithm is ...
示例: 输入: numbers = [2, 7, 11, 15], target = 9 输出: [1,2] 解释: 2 与 7 之和等于目标数 9 。因此 index1 = 1, index2 = 2 。
```java class Solution { public int[] resultArray(int[] nums) { ArrayList<Integer>arr1=new ArrayList<>(); ArrayList<Integer>arr2=new ArrayList<>(); arr1.add(nums[0]); arr2.add(nums[1]); int i=2; while (i<nums.length) { ...
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....
1、Each element in the result must be unique. 2、The result can be in any order. 要完成的函数: vector<int> intersection(vector<int>& nums1, vector<int>& nums2) 说明: 1、给定两个vector,求其交集。交集是一个集合,所以不能出现重复元素,集合不要求顺序。 2、最直接的思路是模仿人类思维,设...
2.1. Plain Java If two arraylists are not equal and we want to findwhat additional elements are in the first list compared to the second list, use theremoveAll()method. It removes all elements of the second list from the first list and leaves only additional elements in the first list. ...
