【Ruby】配列の要素を半角スペース区切りで出力する

Last updated at Posted at 2016-05-01

条件

  • 配列の要素を半角スペース区切りで出力する
  • 末尾の要素は半角スペースでなく改行で出力する

1次元配列の場合

array = ["red", "blue", "white"]
puts array.join(' ')

多次元配列の場合

array = ["red", ["blue", "gold", ["green", "pink"]], ["white", "brown"]]
puts array.join(' ')

Rubyは1次元配列でも多次元配列でも同様に書けるので素敵。
