Solution in JAVA (judge verdict: WA: Presentation Error)

import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
while (true) {
int H = sc.nextInt();
int W= sc.nextInt();
if (H == 0 && W == 0) {
break;
}
for(int i=1; i<=H;i++){
for(int j=1; j<=W;j++)System.out.printf("#");
System.out.printf("\n");
}
}
