JAVA Code:

public class HelloWorld {

 static int count = 0;

 public static void print(int i, int j) {

  if (i <= 0 || j < 0 ) return;

  System.out.print("X ");

  print(i, j - 1);

  if (j == 0) {

   count++;

   System.out.println();

   print(i - 1, count);





  }

 }

   public static void print2(int i, int j) {

  if (i <= 0 || j < 0 ) return;

System.out.print("X ");

print2(i, j - 1);





  if (j == 0) {



   System.out.println();

   print2(i - 1, i-2);





  }

}





 public static void main(String[] args) {

  //System.out.println("Hello World2");

  print(4, 0);

  System.out.println("---------------------");



  print2(4, 3);

 }
