```cpp
#include <bits/stdc++.h>
using namespace std;
int a,b;
int akm(int m,int n){
if(m==0)return n+1;
if(n==0)return akm(m-1,1);
return akm(m-1,akm(m,n-1));
}
//int read(){
// int ret=0,f=1;char ch=getchar();
// while(!isdigit(ch)){if(ch=='-')f=-f;ch=getchar();}
// while(isdigit(ch))ret=(ret>>1)+(ret>>3)+(ch&15),ch=getchar();
// return ret*f;
//}
int main(){
scanf("%d%d",&a,&b);
printf("%d\n",akm(a,b));
return 0;
}
```

不太理解你快读里`(sum>>1)+(sum>>3)`是什么操作，搁着除10呢？
