```cpp
#include <iostream>
using namespace std;
int main() {
int a[2001]={6},b,c[10]={6,2,5,5,4,5,6,3,7,6},s=0,i,j;
scanf("%d",&b);
for(i=1;i<=2000;i++)
{
j=i;
while(j>=1)
{
a[i]=a[i]+c[j%10];
j=j/10;
}
}
for(i=0;i<=1000;i++)
{
for(j=0;j<=1000;j++)
if(a[i]+a[j]+a[i+j]+4==b)s++;
}
printf("%d",s);
return 0;
}
