def rearrange arr,from,to
  sidx = arr.index from
  eidx = arr.index to
  arr[sidx] = arr[sidx+1..eidx]
end

arr= ["Red","Green","Blue","Yellow","Cyan","Magenta","Orange","Purple","Pink","White","Black"]
start = "Yellow"
stop = "Orange"

rearrange arr,start,stop
puts arr.inspect
#=> ["Red",["Cyan","Orange"],"Black"]

我需要在我的开始使用正则表达式并停止搜索,例如

开始=“/大喊/”

停止=“/ Ora /”

有没有一种简单的方法在Ruby中做到这一点？
