{
    public static void main(String args[])
    {
        int i,j,a=2;
        for(i=1;i<=5;i++) // Loop for No. of rows
        {
            for(j=1;j<=i;j++) //Loop for  No. of columns
            {
                if(i==5)
                {
                    a=1;
                    System.out.print(a+"\t");
                }
                else
                {
                    System.out.print(a+"\t");
                }
            }
            System.out.println();
            a++;
        }
    }// end of main method
}// end of class


Pattern 2 :-

            System.out.println();
            a++;
        }
    } // end of main method
} // end of class
