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

import java.util.Scanner;
public class Main{
    public static void main(String[] args){
        Scanner in = new Scanner(System.in);
        int H,W;
         
        H = in.nextInt();
        W = in.nextInt();
         
        while(H!=0 || W!=0){
            
            char[][] sharps = new char[H][W];
            for(int i=0; i<H; i++){
                for(int j=0; j<W; j++){
                    sharps[i][j] = '#';
                }
            }
