I would like to know if there is a method in Ruby that splits an Array of String in smallest pieces. Consider:
我想知道Ruby中是否有一个方法可以将字符串数组分割成最小的部分。考虑:
['Cheese crayon', 'horse', 'elephant a b c']
(“奶酪蜡笔”、“马”、“大象b c”)
Is there a method that turns this into:
有没有一种方法可以把这变成:
['Cheese', 'crayon', 'horse', 'elephant', 'a', 'b', 'c']
[“奶酪”,“蜡笔”,“马”,“象”,“,“b”,“c”)

p ['Cheese crayon', 'horse', 'elephant a b c'].flat_map(&:split)
# => ["Cheese", "crayon", "horse", "elephant", "a", "b", "c"]

None that I know of. But you can split each string individually and then flatten the results into a single array:
我不知道。但是你可以将每个字符串单独分开，然后将结果平摊到一个数组中:
p ['Cheese crayon', 'horse', 'elephant a b c'].map(&:split).flatten

You can do it this way:
你可以这样做:
array.map { |s| s.split(/\s+/) }.flatten
This splits your string by any number of whitespace characters. As far as I know, it's the default behavior of split without any arguments, so you can shorten it to:
这将字符串分割为任意数量的空格字符。据我所知，这是分割的默认行为，没有任何参数，所以可以缩短为:
array.map(&:split).flatten

['Cheese crayon', 'horse', 'elephant a b c'].join(' ').split
# => ["Cheese", "crayon", "horse", "elephant", "a", "b", "c"]
