		Scanner sc = new Scanner(System.in);
			while(sc.hasNext()) {
				int a = sc.nextInt();
				int b = sc.nextInt();
				if(a==0 && b==0) {
					break;
				}
				else {
					for(int i = 0; i < a; i++) {
						for(int j = 0; j < b; j++) {
							System.out.print("#");
						}
						System.out.println();
