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

Solution in PHP (judge verdict: Accepted)

<?php

do {
    fscanf(STDIN, "%d %d", $input['height'], $input['width']);
    $inputs[] = $input;
} while ($input['height'] != 0 && $input['width'] != 0);

foreach($inputs as $input) {
    $result[] = Rectangle::printRectangle($input['height'], $input['width']);
}

echo implode(PHP_EOL.PHP_EOL, $result);

class Rectangle {

    public static function printRectangle($height, $width)
    {
        $rectangle = [];

        for ($i = 0; $i < $height; $i++) {
            $rectangle[] = str_repeat('#', $width);
        }
        return implode(PHP_EOL, $rectangle);
    }
}
