```c
#include<iostream>
using namespace std;
int fun(int x,int y){
if(y==0) return x;
return fun(x^y,(x&y)<<1);
}
int main(){
int a,b;
cin>>a>>b;
cout<<fun(a,b)<<endl;
return 0;
}

```cpp
#include <cstdio>
using namespace std;
int add(int a, int b)
{
if(b)
{
if(b>0)
{
return add(-~a,~-b);
}
else
{
return add(~-a,-~b);
}
}
else
{
return a;
}
}
int main()
{
int a,b;
scanf("%d%d",&a,&b);
printf("%d",add(a,b));

问dalao,dalao告诉我的做法:```cpp
#include<iostream>
using namespace std;
int main(){
long long a,b;
cin>>a>>b;
b=-b;
cout<<a-b;
return 0;
}
```
