Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;
public class Main{
	public static void main(String[] args){
		int a,b,W,H;
		Scanner br=new Scanner(System.in);
		while(true){
			H=br.nextInt();
			W=br.nextInt();
			if(H==0 && W==0){
				break;
				}else{
					for(a=1;a<=H;a++){
						for(b=1;b<=W;b++){
							System.out.print("#");
							}
						System.out.println();
						}
					System.out.println();
					}
			}
		}
