Solution in JAVA (judge verdict: Accepted)

import java.util.Scanner;
public class Main {

	public static void main(String[] args) {
		Scanner scan = new Scanner(System.in);
		int h,w;
		while(true) {
			h=scan.nextInt();
			w=scan.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();
		}
		scan.close();
	}
