Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.
Note:
Example:
Input: nums1 = [1,2,3,0,0,0], m = 3 nums2 = [2,5,6], n = 3 Output: [1,2,2,3,5,6]
AC code:
class Solution {
public:
void merge(vector<int>& nums1, int m, vector<int>& nums2, int n) {
vector<int> nums3;
for (int i = 0; i < m; ++i)
nums3.push_back(nums1[i]);
for (int i = 0; i < n; ++i)
nums3.push_back(nums2[i]);
sort(nums3.begin(), nums3.end());
nums1 = nums3;
}
};
Runtime: 4 ms, faster than 99.52% of C++ online submissions for Merge Sorted Array.
AC code2:
class Solution {
public:
void merge(int A[], int m, int B[], int n) {
int i=m-1;
int j=n-1;
int k = m+n-1;
while(i >=0 && j>=0)
{
if(A[i] > B[j])
A[k--] = A[i--];
else
A[k--] = B[j--];
}
while(j>=0)
A[k--] = B[j--];
}
};
