Here my test case 2 is failed why?

#1

import java.util.*;
public class Main {
public static void main(String args[]) {
// Your Code Here
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();

	int nst = n;
	int row = 1;
	while(row<=n){
		int cst=1;
		while(cst<=nst){
			
			if(row==n-1||row==2) {
				if(cst==n/2+1) {
					
					System.out.print("    ");
					
				}
				else {
					System.out.print("*   ");
				}
			}
			
			else if(row==n/2+1) {
				if(cst==1||cst==nst) {
					System.out.print("*   ");
				}
				else {
					System.out.print("    ");
				}
			}
			
			else {
				System.out.print("*   ");
			}
			
			
			cst++;
			
			}
		System.out.println();
		row++;
	}
}

Hi, you have designed your code specifically for n=5(sample test case).
you need to generalize your code instead of hardcoding it for n=5.
you can try to solve it in two phases.

  1. generate first half part(till n/2 rows)
    you can see that there is " " growing from the middle of column. your condition can be something like if cst is between n/2-rowno to n/2+rowno (you need to fit accurate maths in it), then print " ", otherwise “*”.
  2. then try to generate other half part(row n/2 to n):
    in this case no of " " are contracting. its more like rowno-n/2 to rowno+n/2 condition.

Think about it and try to implement it yourself.
Thanks.
