# [Leetcode] Merge Sorted Array

Source: Internet
Author: User

Given sorted integer Arrays nums1 and nums2, merge nums2 into nums1 as one sorted Array.

Note:
Assume that nums1 have enough space (size that's greater or equal to m + n) to hold add Itional elements from nums2. The number of elements initialized in nums1 and nums2 is m and n respectively.

This problem seems to have nothing to say. relatively simple.

This question is the simplest from the end. Because this is equivalent to inserting a sorted array into another sorted array with extra space.

However, be aware of the special case, the code is written when there is extra space in the sorted array has been sorted after the completion of another array of the element of the sort.

The code is as follows. ~

`public class Solution {public    void merge (int[] nums1, int m, int[] nums2, int n) {        int a=m-1;        int b=n-1;        int start=m+n-1;        while (a>=0&&b>=0) {            if (Nums1[a]>nums2[b]) {                nums1[start--]=nums1[a--];            } else{                nums1[start--]=nums2[b--];            }        }        if (a<=0) {            while (b>=0) {                nums1[start--]=nums2[b--];            }        }    }`
