    Default JAVA for loop

    hi to all..

    i would like to ask if this algorithm is accepted or is it a cheat? thanks

    here's my code
    import java.util.*;
    public class loop1
    {
    	public static void main (String[]args)
    	{
    		int x,y,limit;
     
    		Scanner input = new Scanner (System.in);
    		System.out.print("enter a limit: ");
    		limit = input.nextInt();
     
    		for(x=1;x<=limit;x++)
    		{
    			for(y=x;y<=limit;y++)
    			{
    				System.out.print(" "+y);
    			}	
     
    			System.out.println();
    		}	
     
    		for(x=limit-1;x>=1;x--)
    		{
    			for(y=x;y<=limit;y++)
    			{
    				System.out.print(" "+y);
    			}	
     
    			System.out.println();
    		}	
    	}
    }

    and the output should be like this

    There are no cheats in programming... only odd hacks, strange (and possibly unstable) solutions, and anomalies.

    From reading your code, it looks like you want to print out a half hour-glass thing of numbers. That looks perfectly good to me.
