# Create ASCII Box

Write a function `create_box` that takes three inputs: `height` (rows), `width` (columns), and a character `char` and creates a `height` × `width` box using the character `char`.

For this exercise, it's recommended to use a nested for-loop. There are other ways of solving it (which might be a good starting point), but try reaching the nested for-loop solution.

``````>>> create_box(3, 4, '*')
'****
****
****'
>>> create_box(2, 2, '@')
'@@
@@'
``````

IMPORTANT: You need to `return` your box, not just print it.

### Test Cases

test a 1x1 box -

``````box_1x1_expected = """
@
""".lstrip()

def test_a_1x1_box():
assert create_box(1, 1, '@') == box_1x1_expected
``````

test a 5x8 box -

``````box_5x8_expected = """
xxxxxxxx
xxxxxxxx
xxxxxxxx
xxxxxxxx
xxxxxxxx
""".lstrip()

def test_a_5x8_box():
assert create_box(5, 8, 'x') == box_5x8_expected
``````

test a 3x4 box -

``````box_3x4_expected = """
****
****
****
""".lstrip()

def test_a_3x4_box():
assert create_box(3, 4, '*') == box_3x4_expected
``````
def create_box(height, width, char): pass
