Hi , is it possible to transform the following code to math

```
int F( int n )
{
int r=0;
int mid=n/2;
for( int i=0 ; i<n ; i++)
{
if( i<mid) r+=1 ;
if( i==mid) r*=2 ;
if( i>mid) r=pow(r,3) ;
}
return r ;
}
```

and is this correct ? www.dirbax.com/inventions/dimd-dynamic-intelligent-mathematical-design-/practical-example-1.html

thanks
