如何扁平化一个数组的数组 – 但不是所有的方式

什么是转换这个最好的方法

[[["Club three Team one", 7800], ["Club three Team two", 7801]], [], [["Club four Team one", 7807], ["Club four Team two", 7808]], []] 

成

 [["Club three Team one", 7800], ["Club three Team two", 7801], ["Club four Team one", 7807], ["Club four Team two", 7808]] 

在ruby？ 拼合转换这一路下来

 ["Club three Team one", 7303, "Club three Team two", 7304, "Club four Team one", 7310, "Club four Team two", 7311]

使用flatten(1) http://apidock.com/ruby/Array/flatten

 your_array = [[["Club three Team one", 7800], ["Club three Team two", 7801]], [], [["Club four Team one", 7807], ["Club four Team two", 7808]], []] your_array.flatten(1) #=> [["Club three Team one", 7800], ["Club three Team two", 7801], ["Club four Team one", 7807], ["Club four Team two", 7808]]
