Leetcode-88. Merge Sorted Array
地址:https://leetcode.com/problems/merge-sorted-array/
描述:
Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.
Note:
- The number of elements initialized in nums1 and nums2 are m and n respectively.
- You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2.
实例:
Input: nums1 = [1,2,3,0,0,0], m = 3 nums2 = [2,5,6], n = 3 Output: [1,2,2,3,5,6]
方法:
public int[] merge_4(int[] nums1, int m, int[] nums2, int n){ while(n>0){ nums1[m+n-1]=(m==0||nums2[n-1]>nums1[m-1])?nums2[--n]:nums1[--m];} return nums1; }
