Solution in JAVA (judge verdict: Accepted)

import java.text.DecimalFormat;
import java.util.Scanner;

public class Main {

	static DecimalFormat df = new DecimalFormat("0.0000000000000000000");

	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 = 0; i < h; i++) {
				for (int j = 0; j < w; j++) {
					System.out.print("#");
				}
				System.out.println();
			}
			System.out.println();
		}

		sc.close();
	}
