import java.io.PrintStream;

public class opp1 {

private static PrintStream out;

public static void main(String[] args) {

// TODO Auto-generated method stub

char c1 ='\u2764';

for(float y =(float)2.5;y>-2.5;y -=0.07) {

for(float x=(float) -2.5;x<2.5;x+=0.05) {

float a = x*x+y*y-1;

if((a*a*a-x*x*y*y*y)<=0.0) {

System.out.print("\u2764");

}

else

System.out.print(" ");

}

System.out.println( );

}

}

}
