Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;

public class Main {

	public static void main(String[ ] args) {
		Scanner sc = new Scanner(System.in);

			while(sc.hasNext()) {
				int a = sc.nextInt();
				int b = sc.nextInt();

				if ( (a!=0) && (b!=0) )
				{
					for (int i = 0; i < a; i++) {
						for (int j = 0; j < b; j++) {
							if (j == (b - 1))
								System.out.printf("#\n");
							else
								System.out.printf("#");

						}
					}
				}
				else
					break;
				System.out.println();
			}
	}
