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.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main{

private static final int BIG_NUM=2000000000;
	public static void main(String[]args){
		BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
		
		int H,W;
		String work[]=new String[2];
		
		while(true){
			try{
				work=br.readLine().split("[\\s]+");
				
				if(work[0].equals("0") && work[1].equals("0")){break;}	//両方とも0だったらループを抜ける.
				
				H=Integer.parseInt(work[0]);
				W=Integer.parseInt(work[1]);
				
				//長方形を描画する
				for(int i=0; i<W; i++) {
					for(int j=0; j<H; j++) {
						System.out.printf("#");
					}
					System.out.printf("%n");
				}
				System.out.printf("%n");
				
			}catch(IOException e){
				e.printStackTrace();
			}
		}
	}
