```cpp
const
c:array[0..9] of longint=(6,2,5,5,4,5,6,3,7,6);
var
a,b,n,ans:longint;
function F(x:longint):longint;
begin
F:=0;
repeat
F:=F+c[x mod 10];
x:=x div 10;
until x=0;
end;
begin
//由数据范围估计数字范围
read(n);
n:=n-4;
ans:=0;
for a:=0 to 1000 do
for b:=0 to 1000 do begin
if F(a)+F(b)+F(a+b)=n then inc(ans);
end;
write(ans);
end.
