Code working but problem in submission time

#1

my code is working as needed but at submission time only case 1 is correct and other all are wrong

#2

@deepgarg46 There are two changes that you have to make.
i) Where you have given 1 space there should be 2 spaces there.
ii) and whenever you print and you have to print it like System.out.print(ans+" ");
//Spacing has to be exactly like the sample testcase.
Corrected code is below :

import java.util.*;
public class Main {


	public static void main(String[] args) {

		Scanner scn = new Scanner(System.in);

		int n = scn.nextInt();
		int nst = 1;
		int nsp = n - 1;
		int nsp2 = -1;
		int row = 1;
		while (row <= n) {

			int csp = 1;
			while (csp <= nsp) {
				System.out.print("  ");
				csp++;

			}
			
			int ans = 0;
			int cst = 1;
			while (cst <= nst) {
				ans=cst;

				
				cst++;

			}
			cst = 1;
			while(ans>=cst) {
				System.out.print(ans+" ");
				ans--;
			}

			csp = 1;
			while (csp <= nsp2) {

				System.out.print("  ");
				csp++;
			}
			cst = 1;
			while (cst <= nst) {
				if (row == 1 || row == n) {

					cst++;
				} else {
					System.out.print(cst+" ");
					cst++;
				}

			}
			System.out.println();
			if (row <= n / 2) {
				nst++;
				nsp -= 2;
				nsp2 += 2;
			} else {
				nst--;
				nsp += 2;
				nsp2 -= 2;
			}

			row++;

		}

	}
}
