We can render an ASCII art pyramid with N levels by printing N rows of asterisks, where the top row has a single asterisk in the center and each successive row has two additional asterisks on either side.

Here's what that looks like when N is equal to 3.

  *  
 *** 
*****

And here's what it looks like when N is equal to 5.

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

Can you write a program that generates this pyramid with a N value of 10?

• [execution time limit] 3 seconds (java)
• [memory limit] 2g

class Solution {

    public static void main(String[] args) {

        int N = 10; // Number of levels in the pyramid

        for (int i = 1; i <= N; i++) {

            int spaces = N - i;

            int stars = 2 * i - 1;

            // Print spaces

            for (int j = 0; j < spaces; j++) {

                System.out.print(" ");

            }

            // Print stars

            for (int j = 0; j < stars; j++) {

                System.out.print("*");

            }

            // New line after each level

            System.out.println();

        }

    }

}
