Zipが便利すぎたのでメモ

ZipSample.scala

val pp1 = Seq(1, 2) zip Seq(3, 4)
println(pp1)
// List((1,3), (2,4))


case class Image(width: Seq[Int], height: Seq[Int])
val images = Seq(Image(Seq(200, 300), Seq(210, 310)), Image(Seq(400, 500), Seq(510, 610)))

val pp2 = images.flatMap { b => 
   b.width zip b.height
}
println(pp2)
//List((200,210), (300,310), (400,510), (500,610))
