Merge two given sorted integer array A and B into a new sorted 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 algorithm if one array is very large and the other is very small? 没什么好说的,Arrayl…

两个排好序的数组, A有m个数, 长度够长, B有n个数, 长度为n, 将B放到A里, 不用buffer数组(临时数组), 就用A将两个合在一起, 同时排好序. 方法: 从右边将两个数组里最大的数取出放入A的m+n-1的index处, 从右往左放, 两指针i和j, 直到i和j都等于-1. 注意:时间和空间复杂度: O(m+n) 和 O(1). 空间复杂度即为额外用到的, 这里为0, 即O(1). class Solution { /** * @param A: sorted integer ar…

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 to m + n) to hold additional elements from B. The number of elements initialized in A and B are m …

题目描述 给定两个有序整数数组 nums1 和 nums2,将 nums2 合并到 nums1 中,使得 num1 成为一个有序数组. 说明: 初始化 nums1 和 nums2 的元素数量分别为 m 和 n. 你可以假设 nums1 有足够的空间(空间大小大于或等于 m + n)来保存 nums2 中的元素. 示例: 输入: nums1 = [1,2,3,0,0,0], m = 3 nums2 = [2,5,6], n = 3 输出: [1,2,2,3,5,6] 思路 思路一: 从两个数组中的…
