你如何在Ruby中循环多线字符串？

text = "第一行\n第二行\n第三行"
text.each_line do |line|
  puts line
end

text = "第一行\n第二行\n第三行"
lines = text.split("\n")
lines.each do |line|
  puts line
end

text = "第一行\n第二行\n第三行"
lines = text.lines
lines.each do |line|
  puts line
end

text = "第一行\n第二行\n第三行"
lines = text.each_line.to_a
lines.each do |line|
  puts line
end
