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: Accepted)

i = list(map(int, input().split()))

H = i[0]
W = i[1]

while H != 0 or W != 0 :
    for i in range(H) :
        for j in range(W) :
            print('#', end='')
        if W != 0 :
            print()
    print()
    i = list(map(int, input().split()))

    H = i[0]
    W = i[1]
