Problem:
Print a Rectangle

Draw a rectangle which has a height of H cm and a width of W cm. Draw a 1-cm square by single '#'.

Input

The input consists of multiple datasets. Each dataset consists of two integers H and W separated by a single space.

The input ends with two 0 (when both H and W are zero).

Output

For each dataset, print the rectangle made of H × W '#'.

Print a blank line after each dataset.

Constraints

1 ≤ H ≤ 300

1 ≤ W ≤ 300

Sample Input

3 4
5 6
2 2
0 0

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

import java.util.ArrayList;
import java.util.Scanner;

public class Main {

	public static void main(String[] args){
		ArrayList<String> ary = new ArrayList<String>();
		int x,y;
		String tmp;
		int cnt = 0;
		Scanner sc = new Scanner(System.in);

		x = sc.nextInt();
		y = sc.nextInt();
		tmp = ArrayAdder(x,y);
		ary.add(tmp);
		cnt++;

		while(!tmp.equals("end")){
			sc.hasNext();
			x = sc.nextInt();
			y = sc.nextInt();
			tmp = ArrayAdder(x,y);
			ary.add(tmp);
			cnt++;
		}

		for(int i=0;i<cnt-1;i++){
			System.out.println(ary.get(i));
		}
		sc.close();
	}

	public static String ArrayAdder(int x,int y){
		String result = "";
		if(x==0 && y==0){
