来自两个不同大小数组的 Ruby 数组？

Question

我有两个 Ruby 数组，分别是 days 和 trips，以及星期几:

days = ["Monday", "Tuesday", "Wednesday","Thursday","Friday","Saturday","Sunday"]

还有这里的公交时刻表:

trips = [
  "2.35pm","4.50pm","7.00pm",
  "2.35pm","4.50pm","7.00pm",
  "2.35pm","4.50pm","7.00pm",
  "2.35pm","4.50pm","7.00pm",
  "2.35pm","4.50pm","7.00pm",
  "2.35pm","4.50pm","7.00pm",
  "2.35pm","4.50pm","7.00pm"
]

我试图达到的结果是这样的:

Bus-times = [
  "Monday","2.35pm","4.50pm","7.00pm",
  "Tuesday","2.35pm","4.50pm","7.00pm",
  "Wednesday","2.35pm","4.50pm","7.00pm",
  "Thusday","2.35pm","4.50pm","7.00pm",
  "Friday","2.35pm","4.50pm","7.00pm",
  "Saturday","2.35pm","4.50pm","7.00pm",
  "Sunday""2.35pm","4.50pm","7.00pm"
]

我看过交错，如果我不编写自己的函数，zip 只会返回第一个结果。我还有哪些其他选择？

Answer 1

bus_times = days.zip(trips.each_slice(3)).flatten

或者如果你想将它们保存为数组的数组:

bus_times = days.zip(trips.each_slice(3)).map(&:flatten)
