import java.util.Scanner;

class Main {
public static void main(String[] args) {
  
// declaring variables
int N;
Scanner sc = new Scanner(System.in);
  
// taking user input
System.out.print("Enter value of N: ");
N = sc.nextInt();
char symbol = '*';
  
System.out.println("My Checkboard\n");
  
// for n lines
for(int i=0; i<N; i++)
{
// for 2n symbols in 1 line
for(int j=0; j<2*N; j++)
{
// PRINTING symbol
System.out.print(symbol);
  
// modifying symbol to have alternate * and space
if(symbol == '*')
symbol = ' ';
else
symbol = '*';
}
// since we want differnt symbol in the next line, modifying symbol to have alternate * and space
if(symbol == '*')
symbol = ' ';
else
symbol = '*';
System.out.println();
}
  
}
}

/*SAMPLE OUTPUT
