Solution in JAVA (judge verdict: WA: Presentation Error)

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO ?????????????????????????????????????????????
		int H,W;
		
		Scanner scan = new Scanner(System.in);
		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.printf("#");
				}
				System.out.printf("\n");
				
			}
			
		}
