将子阵列整齐 [英] placing sub arrays in neat rows

问题描述

我目前工作的一个大阵的名称上：

  large_array =鲍勃，乔尔，约翰，史密斯，凯文，将要，斯坦利，乔治]＃，然后让上
 

我将它分成子阵列，像这样：

  large_array.each_sli​​ce（2）.to_a＃=＆GT; [鲍勃，乔尔]，[约翰，史密斯]，[凯文，将要]，[斯坦利，乔治]]
 

我的问题是如何使子阵列在彼此的顶部整齐地排出现这样的：

  [鲍勃，乔尔]
[约翰，史密斯]
[凯文，将要]
[斯坦利，乔治]
 

解决方案

  large_array.each_sli​​ce（2）{| A |把a.inspect}
＃[鲍勃，乔尔]
＃[约翰，史密斯]
＃[凯文，将要]
＃[斯坦利，乔治]
＃=＆GT;零
 

I am currently working on a large array of names:

large_array = ["Bob","Joel","John","Smith","Kevin","Will","Stanley","George"] #and so on

I split it into sub arrays like so:

large_array.each_slice(2).to_a #=> [["Bob", "Joel"],["John,"Smith"],["Kevin", "Will"],["Stanley","George"]]

My question is how do I make the sub arrays appear neatly on top of each other in rows like this:

["Bob", "Joel"]
["John,"Smith"]
["Kevin","Will"]
["Stanley","George"]

解决方案

large_array.each_slice(2) {|a| puts a.inspect}
# ["Bob", "Joel"]
# ["John", "Smith"]
# ["Kevin", "Will"]
# ["Stanley", "George"]
# => nil
