leetcode|88. Merge Sorted Array

问题描述:

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.

Example:

Input:
nums1 = [1,2,3,0,0,0], m = 3
nums2 = [2,5,6],       n = 3

Output: [1,2,2,3,5,6]

问题解析:

对于nums1来说,目标是有效数字长度,可能nums.size()!=m哦

直接用了内置函数……这样会不会不太好

//6ms
class Solution {
public:
    void merge(vector<int>& nums1, int m, vector<int>& nums2, int n) {
        for(int i=0;i<n;i++){
            nums1[nums1.size()-n+i]=nums2[i];
        }
        sort(nums1.begin(),nums1.end());
        
    }
};
