ruby - Rails 3-从阵列A移除属于阵列B的项目

我开始使用数组，但是我坚持使用看起来但非常简单的东西...
我正在尝试从另一个数组中删除属于一个数组的x个元素。
我已经看过了，但是....阻止了:
Deleting items from an array requires multiple passes to remove them all

a = ["1","2","3","4","5","6"]
b = ["1","3"]
c = a.reject { |i| i =~ /b/ }

好吧，我在这里很多，谢谢!

最佳答案

a = ["1","2","3","4","5","6"]
b = ["1","3"]
c = a - b

和...一样

c = a.reject{ |e| b.include? e }
