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 Ruby (judge verdict: Accepted)

#encoding:utf-8
rectangle = []
while true
 length_width = gets.split
 if length_width == ["0","0"]
  break
 end
 rectangle.push length_width
end

i = 0 #rectangleの要素のインデックス

while i < rectangle.length
 j = 0 #縦の繰り返し回数をカウント
 while j < rectangle[i][0].to_i
  puts "#"*rectangle[i][1].to_i
  j += 1
 end
 puts
 i += 1
end
