{
        int i,j;
        for(i=0,j=0;i<321;i++)
                if(i%111==0) j++;
        if (j==3) return true; else return false;

        for (i=1;i<100;i++) a[i]=sqrt(a[i-1]);
        if (a[77]>a[66]) return true; else return
false;
}

int main()
{
        if ( f1() > 0 ) return true;
        else return false;
}
