Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;
class Main{
 public static void main(String[] args){
  Scanner scan = new Scanner(System.in);
  while(true){
   int h = scan.nextInt();
   int w = scan.nextInt();
   if(h == 0 && w == 0){
    break;
   }
   for(int i = 0; i < h; i++){
    for(int j = 0; j < w; j++){
     System.out.print("#");
    }System.out.println();
   }System.out.println();
  }
 }
