import java.util.Scanner;
 
public class Main
{
  public static void main(String args[])
  {
    int rows, i, j;
    Scanner sc = new Scanner(System.in);
 
    System.out.print("Enter the no. of rows: ");
    rows = sc.nextInt();
 
    for (i = 1; i <= rows; i++)
    {
      for (j = i; j <= rows; j++)
        System.out.print(j + " ");
 
      for (j = i - 1; j >= 1; j--)
        System.out.print(j + " ");
 
      System.out.println();
    }
  }
}

Output:

Enter the no. of rows: 5
1 2 3 4 5
2 3 4 5 1
3 4 5 2 1
4 5 3 2 1
5 4 3 2 1
