最大与字符串

Question

我做提取最小的字有一个字符串作为"Frederik will not come office tomorrow.So please you have to do his tasks".我想最小和最大长度字作为散列如下：

{2=>["So", "to", "do"], 8=>["Frederik", "tomorrow"]} 

那么这将是这样做最短的方法吗？

Answer 1

尝试以下：

w = "Frederik will not come office tomorrow.So please you have to do his tasks" 
p Hash[w.scan(/\w+/).group_by(&:length).minmax] 

#=>{2=>["So", "to", "do"], 8=>["Frederik", "tomorrow"]}
