我将如何在 Ruby 中执行此操作?

会回来:

["abc","acb","bca","背","cba",出租车"，]

感谢 Jakub Hampl:

class 字符串def all_possible_permutationsself.chars.to_a.permutation.map(&:join)结尾结尾

解决方案

%w[a b c].permutation.map &:join

How would I do this in Ruby?

p "abc".all_possible_permutations

Would return:

[ "abc", "acb", "bca", "bac", "cba", "cab", ]

Edit

Thanks to Jakub Hampl:

class String def all_possible_permutations self.chars.to_a.permutation.map(&:join) end end

解决方案

%w[a b c].permutation.map &:join
