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: Wrong Answer)

import java.util.*;

public class Main{
	private static final Scanner scan = new Scanner(System.in);

	public static void main(String[] args){
		List<Integer> listH = new ArrayList<Integer>();
		List<Integer> listW = new ArrayList<Integer>();
		for(;;){
			int H = scan.nextInt();
			int W = scan.nextInt();
			if(H == 0 && W == 0){
				break;
			}
			listH.add(H);
			listW.add(W);
		}

		for(int i = 0; i < listH.size(); i++){
			StringBuffer sb = new StringBuffer();
			for(int j = 0; j < listW.get(i); j++){
				sb.append("#");
			}
			sb.append("\n");
			String str = sb.toString();
			System.out.print(str);
		}
		System.out.println("");
	}
}
