LeetCode每日一题：归并两个有序数组

问题描述

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

问题分析

其实考察的是归并排序，但是更加简便的方法就是两个数组合在一处再排序，虽然能AC，但不符合算法的要求

代码非正确方法实现

public void merge(int A[], int m, int B[], int n) {
        for (int i = 0; i < n; i++) {
            A[i + m] = B[i];
        }
        Arrays.sort(A);
    }
