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

import java.util.Scanner;
public class Main {
   public static void main(String[] args){
     Scanner scanner = new Scanner(System.in);
     for(int i=1;i>0; i++){
          int H = scanner.nextInt();
          int W = scanner.nextInt();
          if(H==0&&W==0)break;
          for(int j=1;j<=H; j++){
              for(int k=1;k<=W; k++){
              System.out.print("#");
              }
              System.out.println(" ");
          }
          System.out.println(" ");
