import java.util.*;
public class Main
{
        public static void main(String[] args) {
            //Scanner Object for input
                Scanner sc=new Scanner(System.in);
                int n;
                //take user input
                System.out.print("Enter the number: ");
                n=sc.nextInt();
                System.out.print("*  |");
                for(int i=1;i<=n;i++){
                    System.out.printf("%4d",i);
                }
                System.out.println();
                System.out.print("----");
                for(int i=1;i<=n;i++){
                    System.out.print("----");
                }
                //nested loop to print the table
                System.out.println();
                for(int i=1;i<=n;i++){
                    System.out.printf(" %d |", i);
                    for(int j=1;j<=n;j++){
                        System.out.printf("%4d",i*j);
                    }
                     System.out.println();
                }
        }
