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