```cpp
#include <bits/stdc++.h>
using namespace std;
int main()
{
long long a,b,c=0,d[10000],e[10000],ans=2,an = 2;
cin >>a>>b;
for(int i = 1;i <= a;i++){
d[i]=i;
}
for(int i = 1;i <= a;i++){
if(d[i]>9){//从这开始有问题 不需要分两种情况讨论
while(ans > 1){
ans = d[i]/10;
an = d[i]%10;
if(ans == b){//这里对同一个数会反复判断
c++;
}
if(an == b){
c++;
}
}
ans = 2;
}
else{//这里可以去掉
if(d[i]==b){
c++;
}
}
}
cout<<c;
return 0;
}
```

//AC代码
```cpp
#include <bits/stdc++.h>
using namespace std;
int main()
{
long long a,b,c=0,d[10000],ans,an;
cin >>a>>b;
for(int i = 1;i <= a;i++){
d[i]=i;
}
for(int i = 1;i <= a;i++){
ans=i;
while(ans!=0){
an =ans%10;
ans=ans/10;
if(an == b){
c++;
}
}
}
cout<<c;
return 0;
}
```
