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

Solution in Python3 (judge verdict: WA: Presentation Error)

while True:
    rectangle_item = []
    h, w = map(int, input().split())
    if h == 0 and w == 0:
        break
    wide = '#' * w
    for i in range(1, h + 1):
        rectangle_item.append(wide)
    rectangle = '\n'.join(rectangle_item)
    print(rectangle)
