Hello Devs

I want to print a pyramid like shown below

        *
      * * *
    * * * * *
  * * * * * * *
* * * * * * * * *



Now , consider the code

C#
class StarPyramid
{
    public static void main(String arr[])
    {
    int n=6;
    for(int i=0;i<n;i++)
    {
        for(int j=n;j>=i;j--)
        {
            System.out.print(" ");
        }
        
        for(int k=0;k<i;k++)System.out.print("#");
        //If i use the loop mentioned below , then i get asymmetrical pyramid
        //for(int m=0;m<i;m++)System.out.print("#");        
        
        
        System.out.println(" ");
    }
        
    }
}


What I have tried:

Thanks in advance !!

You should learn to use the debugger as soon as possible. Rather than guessing what your code is doing, It is time to see your code executing and ensuring that it does what you expect.

The debugger allow you to follow the execution line by line, inspect variables and you will see that there is a point where it stop doing what you expect.

The debugger is here to show you what your code is doing and your task is to compare with what it should do.
When the code don't do what is expected, you are close to a bug.

Advice: tale a sheet of paper and try to do it by hand, your program should use the same procedure.
Make a table with 3 columns "Line #", "#spaces" and "# stars" and fill it
