Output

For each dataset, print the rectangle made of H × W '#'.

Print a blank line after each dataset.

Constraints

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

def print_rect(h, w)
  h.times do
    puts "#" * w
  end
end

ARGF.each_line do |line|
  h, w = line.split.map(&:to_i)
  break if [h, w].all?(&:zero?)
  print_rect h, w
end
