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++){
if(i>n/2){
System.out.print(i);
for(int k=1;k<=i-2;k++){
System.out.print(“0”);
}
System.out.print(i);
}
else{
for(int j=1;j<=i;j++){
System.out.print(i);
}
}
//}

Hi Donnaghai

Firstly, please send your code by pasting it in ide.codingblocks.com, saving it and then sending the link here. Secondly, you need to add tab after printing any value, as shown in the sample I/O too.

Made the required changes to your code.

import java.util.*;

public class Heap1 {

public static void main(String args[]) {
	Scanner sc = new Scanner(System.in);
	int n = sc.nextInt();
	for (int i = 1; i <= n; i++) {

		if (i > n / 2) {
			System.out.print(i + " ");
			for (int k = 1; k <= i - 2; k++) {
				System.out.print("0" + " ");
			}
			System.out.print(i);
		} else {
			for (int j = 1; j <= i; j++) {
				System.out.print(i + " ");
			}
		}
		System.out.println();
	}
}
