잘돌아가는데 왜 틀렸다하누,,

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		
	    Scanner sc = new Scanner(System.in);
	    int n  = sc.nextInt();
	    for(int i=1; i<=n; i++) {
	    	for(int j=1; j<=i; j++) System.out.print("*");
	    	for(int k=n-i; k>0; k--) System.out.print(" ");
	    	for(int k=n-i; k>0; k--) System.out.print(" ");
	    	for(int j=1; j<=i; j++) System.out.print("*");
	    	System.out.println();
	    }
	    for(int i=n-1; i>0; i--) {
	    	for(int j=i; j>0; j--) System.out.print("*");
	    	for(int k=1; k<=n-i; k++)System.out.print(" ");
	    	for(int k=1; k<=n-i; k++)System.out.print(" ");
	    	for(int j=i; j>0; j--) System.out.print("*");
	    	System.out.println();
	    }
		sc.close();
	}
}

위아래 각 4파트로 나눠야 돌아가나봄 ㅎㅎ;;

정말 모르겠다 백준의 기준
