   Problem Number: 03
   Problem Title : Print arrow head of goven size
   
   Theory : 

    	Consider following facts 

	1. The statement   
		System.out.println(); 
	   will move the cursor to a new line

	2. The statement   
		System.out.println("*"); 
	   will print a * on current cursor position

  	3. If we execute Stetement 
		System.out.println("*"); 
	   x times Then x number of * will appear on current curser position
	   Let's combile fact 1 and 2 , to print x times * on a new line, following statement is to be written
		
     		{
			System.out.println();
			for( i = 1 ; i <= x ; i = i + 1) System.out.print("*");
		}

	4.  Now our program is easy
	    To print arrow head of size s
            4a. To print upper head
                   ---  *
		    ^	**
	            |	***
		    s	****
	            |	*****
                    |   ******
	           ---  *******
                call above body (fact 3) with value ox x in increasing order satrting fron 1 upto s

	    4b. to print bottom part
		   ---  ******
		    ^	*****
	            |	****
		   s-1	***
	            |	**
	           ---  *
                call above body (fact 3) with value ox x in decreasing order order satrting fron s-1 to 1
