## 题目描述

Given two sorted integer arrays A and B, merge B into A as one sorted array.

Note:

You may assume that A has enough space to hold additional elements from B. The number of elements initialized in A and B are m and n respectively.

## 代码

```
class Solution {
public:
void merge(int A[], int m, int B[], int n) {
// IMPORTANT: Please reset any member data you declared, as
// the same Solution instance will be reused for each test case.
int cur = m - 1;
for(int i = 0; i < n; i++)
{
while(cur >= 0 && A[cur] >= B[n-1-i])
A[cur+n-i] = A[cur--];
A[cur+n-i] = B[n-1-i];
}
}
};
```
