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: Accepted)

import java.io.*;
public class Main {
	public static void main(String[] args){
		BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
		try{
        	while(true) {
        		String line = reader.readLine();
        		String[] num = line.split(" ", -1);
        		int H = Integer.parseInt(num[0]);
        		int W = Integer.parseInt(num[1]);
        		if (H == 0 && W == 0) {
        			break;
        		} else {
        			for (int i = 0; i < H; i++) {
        				for (int j = 0; j < W; j++) {
        					System.out.print("#");
        				}
        				System.out.println();
        			}
        			System.out.println();
        		}
        	}
        } catch (IOException e) {
          System.out.println(e);
        } catch (NumberFormatException e) {
