When I run this code :
import java.util.*;
public class Main {
public static void main(String args[]) {
System.out.println(“Enter the number of rows”);
Scanner sc=new Scanner(System.in);
int N=sc.nextInt();
for(int j = N ; j >= 1 ; j--){
for(int i = j-1 ; i >0 ; i--) {
System.out.print(" ");
}
for(int k = j; k < j+N;k++){
if(j==1 || j== N)
System.out.print("*");
else{
if( k == j || k==j+N-1){
System.out.print("*");
if(k < j+N-1){for(int l = j+1 ; l < j+N-1 ; l++){
System.out.print(" ");
}
}
}
}
}
System.out.println();
}
}
}
in my IDE it works fine but on the website ,its showing me the following error: Exception in thread “main” java.util.NoSuchElementException
