合并c中的两个排序数组

Question

Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. my solution is not working can anyone help

enter code here 
void merge(int* nums1, int m, int* nums2, int n) {
int i=0,j=0,k=0;
while(i<m&&j<n)
{
    if(nums1[i]<nums2[j])
    {
        nums1[k]=nums1[i];
        i++;
        k++;
    }
    else if (nums1[i]>nums2[j])
    {
        nums1[k]=nums2[j];
        k++;
        j++;
    }
    else
    {nums1[k]=nums1[i];
        k++;i++;j++;}
}

while(i!=m)
{  
    nums1[k]=nums1[i];
      k++,i++;


}
while(j!=n)
{
    nums1[k]=nums2[j];
      k++,j++;

}

return nums1;

}

compiler is saying output is wrong.. its a question on leetcode

Answer 1

The question is that number in nums2 will replace nums1's number when nums2' number is larger, and this will modify numbers in nums1. You can use another buffer to store the result instead of using nums1, or merge them from the end of both.
