Array Pyramid

[zameel amjed]

Is that possible to get Output of a pyrmid using following Array elements? :rolleyes

String x[] ={"[*]","[]","^"};



output -
^
[][]
[*][*][*]

[Joanne Neal]

Yes. But nobody's going to give you the code until you show us what you have tried so far. ShowSomeEffort

[ankittt agarwala]

ya try it out seems possible and then tell the error if you encounter any

[Campbell Ritchie]

Welcome to the Ranch

Yes, it is possible, but I suggest you try this first, to get the print-out you want. I think that will be easier.

String x[] ={"^","[]","[*]"};

[zameel amjed]

Solved!

class A{
public static void main(String...args){
	String x[]={"^","[]","[*]"};	
	System.out.println(x[0]);
		for(int i=x.length;i<9;i++){
			for(;i<5;	i++){
				System.out.print(x[1]);
				for(;i==4;i++){
				System.out.println();
				}
			}
		System.out.print(x[2]);
		}
	}
}

Is any other methods using less FOR LOOPs..?

Thanks Ritchie

[Campbell Ritchie]

Yes. That looks a complicated solution.

[Campbell Ritchie]

What you want is to count up to three, and for each of those numbers print out the array member that many times. So you need two loops nested inside each other, if you use the array I showed you earlier. It is a bit more complicated because arrays start at no 0.

[][]
[*][*][*]

That's not a pyramid

     /\
    [][]
[*][*][*]

That's a pyramid :P

[Campbell Ritchie]

You will need to print some spaces before your Strings. Maybe 3 spaces first time, then two, then one.

[zameel amjed]

Came up with a better solution...
Used 2x spaces to arrange the pyramid in good shape....

class A{
public static void main(String...args){
	String x[]={"^","[]","[*]"};	
		for(int i=0;i<x.length;i++)
		{
			for(int j=x.length;j>i;j--){
			System.out.print("  ");
			}			
			for(int k=-1;k<i;k++){
			System.out.print(x[i]);
			}			
		System.out.println();
		}
	}
}
