## OLD

# DO NOT MODIFY THE CODE BELOW THIS LINE!
_elements_cnt = 0
_elements_cnt = Integer(gets)
_elements_i=0
_elements = Array.new(_elements_cnt)

while (_elements_i < _elements_cnt)
  _elements_item = gets.to_s.strip;
  _elements[_elements_i] = (_elements_item)
  _elements_i+=1
end

res = rearrange(_elements);
for res_i in res do
  puts res_i
end

## REVISED

_elements_cnt = Integer(gets)
_elements = Array.new(_elements_cnt)

_elements_cnt.times do |i|
  _elements[i] = gets.to_s.strip
end

_res = rearrange(_elements)
_res.each do |line|
  puts line
end

## EVEN MORE SHORT

elements = gets.to_i.times.map { gets.to_s.strip }
rearrange(elements).each { |line| puts line }
