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)

square = []
while True:
    data = [int(e) for e in input().split()]
    if data[0]==0 and data[1]==0:
        break
    square.append(data)
    
for i in range(len(square)):
    for j in range(square[i][0]):
        for k in range(square[i][1]):
            print("#", end="")
        print()
