Lintcode: Merge Sorted Array II Merge two given sorted integer array A and B into anewsorted integer array. Example A=[1,2,3,4] B=[2,4,5,6]return[1,2,2,3,4,4,5,6] Challenge How can you optimize your algorithmifone array is very large and the other is very small?
先复习下原本我们在MergeSort里面怎么利用一个新建的数量来merge two array: 代码如下: 1publicint[] mergeTwoList(int[] A,int[] B) { 2int[] C =newint[A.length + B.length]; 3intk = 0; 4inti = 0; 5intj = 0; 6while(i < A.length && j < B.length) { 7if(A[i] < B[j]) ...
The final sorted array should not be returned by the function, but instead bestored inside the arraynums1. To accommodate this,nums1has a length ofm + n, where the firstmelements denote the elements that should be merged, and the lastnelements are set to0and should be ignored.nums2has ...

Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. Note: You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2.The number of elements initialized in nums1and nums2 are m...
Leetcode每日一题:88.merge-sorted-array(合并两个有序数组),思路:最容易想到的就是归并排序的归并策略了,时间复杂度O(m+n),空间复杂度O(n);但是官网给出了另一个难以想到的妙招,就是反向归并,因为nums1最后面的n个元素是空的,所以从后端开始归并,每次选择较大的放
In this tutorial, we’re going to learn how to merge two sorted arrays into a single sorted array. 2. Problem Let’s understand the problem. We have two sorted arrays and we would like to merge them into one. 3. Algorithm When we analyze the problem,it’s quite easy to observe that...
Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. The number of elements initialized in nums1 and nums2 are m and n respectively. You may assume that nums1 has a size equal to m + n such that it has enough space to hold additional element...
