Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array.
Note:
You may assume that nums1 has enough space (size that is greater or equal to m + n) to hold additional elements from nums2. The number of elements initialized in nums1 and nums2 are m and n respectively.
我们数据结构书上在讲归并排序时，是将数组插入到新的数组中，这个是插到原来的数组中，我们只需要将第二个数组的元素一个一个插进来就好
class Solution {
public:
void merge(vector<int>& nums1, int m, vector<int>& nums2, int n) {
nums1.resize(m + n);
int nums1_postion = 0, nums2_postion = 0, count_nums2 = 0;
for (;nums1_postion<m + n&&nums2_postion < n;++nums1_postion)
{
if (nums1_postion >= m + count_nums2 || (nums1[nums1_postion] > nums2[nums2_postion]))
{
++count_nums2;
int temp = m+count_nums2-1;
for (;temp > nums1_postion;--temp)
{
nums1[temp] = nums1[temp - 1];
}
nums1[nums1_postion] = nums2[nums2_postion++];
}
}
}
};
