使用Scala取消旋转地图/列表/元组

Question

I have something like this:

val m1 = Map(A -> List(("a","b"),("c","d"),("e","f")))

I want the result to be :

(Map(A -> List("a","b")), Map(A -> List ("c","d")), Map(A -> List("e","f")))

could anyone help?

Thanks

It's hard to tell what exactly you are trying to do, but here is a way to convert m1 to the desired structure:

val m1 = Map("A" -> List(("a","b"),("c","d"),("e","f")))
m1.toList.flatMap { case (key, tuple) =>
 tuple.map(v => Map(key -> List(v._1, v._2)))
}
