ruby - 以不同的方式遍历多个数组

Question

虽然我正在尝试在 Ruby 中解决这个问题，但我欢迎使用其他语言提出建议，我可以将这些建议带回 Ruby。

我有任何数组:

color = ["red", "green", "blue"]
size = ["small", "medium", "large"]
style = ["loose", "tight"]

我需要为每个 可能的组合创建字符串。例如:

"red small loose", "red small tight", "red medium loose", "red medium tight", "red large loose", "red large tight", "green small loose", etc...

我愿意接受任何建议。

Answer 1

>> color.product(size, style).map { |strings| strings.join(" ") }
#=> ["red small loose", "red small tight", ..., "blue large tight"]
