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)

if __name__ == '__main__':
	h,w = map(int, input().split())
	while h+w != 0:
		for i in range(h):
			s=""
			for j in range(w):
				s=s+"#"
			print(s)
		print()
		h,w = map(int, input().split())
