````cpp`
你的代码

@[NoaHD](/space/show?uid=88463) 发代码请在代码前后各空一行加上三个"`"符号，或者使用工具栏的"插入代码"按钮

```cpp
include<iostream>
using namespace std;
int f2(int n)
{
if(n==1) return n;
return n*f2(n-1);
}
int f(int n)
{
int result=0; int count = n; while(count>0)
{
result = f2(count)+result;
--count;
}
return result;
}
int main()
{
int n;
cin>>n;
cout<<f(n);
}
```
