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

import java.util.Scanner;

class Main {
  public static void main(String args[]) {
	  	Scanner scanner = new Scanner(System.in);
	  	boolean J = true;
	  	int i,j;
	  	
	  	while(J) {
	  		
		  	int  w = scanner.nextInt();			//入力
		  	int  h = scanner.nextInt();
		  	
		  	if( h == 0 && w == 0 )
		  		break;
	  		
		  	for(i = 1; i <= h ; i ++){
		  		for(j = 1; j <= w ; j++){
		  			if(j == w) {
		  				if(i == h)
		  					System.out.println("# ");
