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

Solution in PHP (judge verdict: WA: Presentation Error)

<?php
while(true)
   {
       $stdin = trim(fgets(STDIN));
       if ($stdin === '0 0')
       {
         $height = 0;
         $width = 0;

         for ($i=0; $i < count($stdins); $i++) {
             $hw = explode(" ",$stdins[$i]);
             $height = $hw[0];
             $width = $hw[1];
            //  echo 'height:'.$height .'width:'.$width ."\n";
             for ($j=0; $j < $width ; $j++) {
               for ($k=0; $k < $height; $k++) {
                 echo "#";
               }
               echo "\n";
           }
           echo "\n\n";
         }
           return;
       }
       $stdins[] = $stdin;
   }
