ruby - 如何在 Ruby 中以特定方式组合两个数组数组

Question

假设我有这两个数组:

a = [[1],[2],[3]]
b = [[4],[5],[6]]

有没有一个选项可以让我像这样组合它们:

a.combined_somehow(b) == [[1,4],[2,5],[3,6]]

因为我希望它防止我在内部数组中重复。我的意思是，如果它是:

a = [[1],[2],[3]]
b = [[1],[5],[3]]

输出将是:[[1],[2,5],[3]]

Answer 1

a = [[1],[2],[3]]
b = [[4],[5],[6]]

a.flatten.zip(b.flatten).map(&:uniq) # => [[1, 4], [2, 5], [3, 6]] 

b = [[1],[5],[3]]
a.flatten.zip(b.flatten).map(&:uniq) # => [[1], [2, 5], [3]]
