显然你这是暴力

不暴力就不会写了

```c
#include<bits/stdc++.h>
using namespace std;
int main()
{
long long x,y,ans=0;
int left,right;
char num=0;
cin>>x>>y;
for(long long i=x;i<=y;i=i+1)
{
num=char(i);
if(strlen(num)==1) ans=ans+1;
else
{
for(int a=0;a<strlen(num);a=a+1)
{
left=0;
right=0;
for(int m=0;m<(n-0);m=m+1) left=left+int(num[m])*(n-m);
for(int m=n+1;m<strlen(num);m=m+1) right=right+int(num[m])*(m-n);
if(left-right==0)
{
ans=ans+1;
break;
}
}
}
}
cout<<ans;
return 0;
}
```

用了c++出了问题
by lelaimc @ 2024-02-20 14:09:15
编译失败了
