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) {
    final int H = sc.nextInt();
    final int W = sc.nextInt();
    if (H == 0 && W == 0) {
     break;
    }
    for (int y = 0; y < H; y++) {
     for (int x = 0; x < W; x++) {
      System.out.println("#");
     }
     System.out.println("\n");
    }
   }
 }
