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.*;
class Main{
     public static void main(String[] args){
         Scanner sc=new Scanner(System.in);
         while(true){
         int H = sc.nextInt();
         int W = sc.nextInt();
         if(H==0 && W==0)  break; 
         int i,j;
         for(i=0;i<H;i++)
         {
             for(j=0;j<W;j++)
             {
                 System.out.print("#");
             }
             System.out.println();
         }
         System.out.println();
